The majority of specimens were collected from the +type +locality, at the mouth of outlet of Indaw Inn into +Ayeyarwady +River. At the time of collection (June–July, beginning of floods) all sampling sites were along edges of floodplain lakes, backwaters and the +Ayeyarwady +proper, with murky water and mud bottom. At three sites, + +P. castor + +and + +P. pollux + +were collected together. The species were not identified in the field and no habitat preference could be noted. At two sites, + +P. castor + +was more abundant ( +Fig. 10A +), and at the third site ( +Fig. 10B +) + +P. pollux + +was more abundant. At the time of collection, this last site was a small ponded stream, separated from a lake, but which floods would soon connect; the stream was flowing from an area shaded by trees and bushes and the water was slightly clearer. This suggests that + +P. pollux + +might prefer clearer water and shade. + + + + +Etymology. +Castor, the mortal twin half-brother of Pollux in Greek mythology, who gave the name of a star of the constellation and astrological sign of Gemini (twins).

The new species differs from + +A. singuladentis + +in some significant ways. The aperture is kidney-shaped (vs. circular in + +A. singuladentis + +); apertural teeth consist of parietal and palatal teeth (vs. only parietal tooth in + +A. singuladentis + +), and the whorl number ranges from 4–4.5 (vs. +3.5 in + +A. singuladentis + +) ( +Table 3 +). The apertural teeth of + +A. pallgergelyi + +consist of parietal and palatal teeth, and share this characteristic with only + +A. dominikae + +, + +A. huoyani + +, and + +A. tamlod + +. This new species can be distinguished from these three species by having teleoconch sculpture irregular growth lines crossed with fine spiral threads and the umbilicus deep and relatively narrow. In contrast, the other species have spiral threads and narrow umbilicus. + + + + +Fig. 2.

Kidman-Cox +, + +1 August 1972 + +, presented by Reptile Section. + + + + + +Diagnosis. +Carapace wider than long, relatively high, dorsal surface of carapace convex; epigastric cristae rugose, not sharp, anterior of postorbital cristae; postorbital cristae sharp, sloping posteriorly from front; median lobe of posterior margin of epistome acutely triangular ( +Fig. 4A–C +). P2–P5 merus relatively long, dactylus of P5 long. Press-button of male pleonal locking mechanism on median part of sternite 5 ( +Fig. 5A +). Male pleon distinctly triangular ( +Fig. 5F, G +). G1 gently sinuous; subterminal segment relatively long, with basal part broad, forming subrectangular structure, distal part slender; terminal segment strongly sinuous, curved, distal part bifurcated, subdistal projection as long as distal projection, lobiform with rounded tip, laterally flattened ( +Figs. 5B–E +, +6E–G +). Female unknown. + + +Females and variation. +Only known from the +holotype +male. + + + + +Etymology. +The species is named after Alice +Georgie +Cruickshank “Bunty” Grandison, a well-respected, pioneering female herpetologist and museum curator (see information on collectors). + + + + +Remarks. +The bifurcated distal part of the G1 of + +I +. +buntyae + +, +new species +, is diagnostic and places this species in a group with four other species sharing this character: + +I +. +griswoldi + +(Mount Kinabalu, Sabah), + +I +. +collinsi + +(Gunung Mulu and +Brunei +), + +I +. +nimboni + +(southern and central +Sarawak +), and + +I +. +grusophallus + +(southern +Sarawak +). Although +Ng & SH Tan (1998) +recognised + +I +. +stuebingi +Ng, 1995b + +, as a distinct species, it has been subsequently shown that the +holotype +is just a subadult specimen of + +I +. +nimboni + +and the two names are now regarded as synonyms (cf. +Ng, 2004: 324 +; +Ng et al., 2008: 163 +). + + +The G1 subdistal process of + +I +. +grusophallus + +is the most distinctive, being prominently elongate and more than twice the length of the distal part (cf. +Ng & Yang, 1986 +: fig. 1H–K; +Ng, 1987b +: fig. 3G, H; +Ng & SH Tan, 1998 +: fig. 6A–D; Grinang et al., 2014: fig. 5A, B, D, E, H–K, M–P, R–T). The G1 of + +I. griswoldi + +is the shortest proportionately among all the members of this group of species, with the subdistal process short and almost rounded in appearance ( +Chace, 1938 +: pl. 1f–h; +Bott, 1969 +: fig. 2; +Bott, 1970 +: pl. 41, fig. 78; +Ng & SH Tan, 1998 +: fig. 5M–P). The general features of the G1 of + +I. buntyae + +most closely resemble those of + +I. collinsi + +and + +I. nimboni + +. Compared to + +I. buntyae + +, the G1 terminal article of + +I. collinsi + +is gently sinuous and the subdistal process is subcylindrical in shape and distinctly longer than the distal process and positioned at a right angle with respect to the main stem of the terminal article ( +Fig. 7D, E, F, G, I, J, K, L +; +Holthuis, 1979 +: fig. 4b; +Ng, 1987b +: fig. 3F; +Ng & SH Tan, 1998 +: fig. 5A–D (vs. terminal article strongly sinuous with the subdistal process laterally flattened and slightly longer than the distal process in + +I. buntyae + +; +Figs. 5B–E +, +6E–G +). In + +I. nimboni + +, the G1 terminal segment is similar to that of + +I. collinsi + +, being gently sinuous to almost straight but the subdistal process is conical in shape, subequal to the distal process in length and positioned at a more acute angle ( +Ng, 1987b +: fig. 2H–J; +Ng & SH Tan, 1998 +: fig. 10I–L). + + +Ng & Goh (1987: 328 +, pl. 3C, D) reported a female specimen from near Gomantong in eastern +Sabah +which could not be identified to the species level. This site is some +42 km +to the southeast of Ulu Dusun.

(2014) confirmed that the species was from the Pulong Tai National Park area on the eastern drainage of the Baram River. The locality data for the new species, + +I. feeae + +, +new species +, is not detailed, but as it is a different species, it was likely to have been collected from the western catchment of the Baram River which drains from a different mountain range. More collections in that area will need to be made to confirm this supposition. + + +Not unexpectedly, the species closest to + +I. feeae + +, +new species +, is + +I. borneense + +, which occurs in the eastern drainage of Baram River (Grinang et al., 2014). The G1 of + +I. feeae + +, however, differs markedly from that of + +I. borneense + +in having the G1 subterminal segment proportionately longer, the terminal segment more strongly curved and sinuous, and the distal part of the terminal segment more elongate with the distal margin distinctly sinuous ( +Figs. 3D–G +, +6A–C +) (cf. +Ng & SH Tan, 1998 +: fig. 1M–P; Grinang et al., 2014: figs. 3A–D, E, G–I, J, L–M).

Lim +, + +18 August 1993 + + +. + + + + +Remarks. +Some additional comments on the bottle of specimens associated with NHM registration number “ +1898.11.28 +” are necessary. The outside jar label actually only provides the following information in ink: “1898.11, Penang, S.S. Flower Esq” and is headed in pencil by “ + +Potamon + +”. This documentation is in the handwriting of curator Jeffrey Bell (see +Ingle, 1991 +). In the Zoological Accessions, Crustacea Register, there is, however, no entry for just “1898.11”. Instead, it appears to be “ +1898.11.28 +”, a registration number that is repeated, once in black ink and below in red. The entry associated with this is confusing, because it states “1–4, + +Anchistes inermis + +(in + +Pinna + +), Kosichang, Gulf of +Siam +, Pres Capt. S.S. Flower.” This too is in the handwriting of curator Jeffrey Bell and the locality is different than that on the jar. Inserted after this in black ink is “(L.A. Borradaile det 1/15)”, followed in red ink by, “Bottle found with incomplete Reg. No. as given in red WTC (William Thomas Calman) 21.1.15.” Above + +“ +inermis + +” is an arrow followed by, “= +custus +Forsk.” This suggests that Calman had a problem finding this specimen of + +Anchistus inermis + +(Miers, 1884; probably under + +Harpilius + +) for Borradaile to examine on a Museum visit dated +21 January 1915 +, when the identification of the specimen was redetermined as “ +Anchistes custus +Forskål, 1775” while Borradaile was working on his Pontoniidae revision ( +Borradaile, 1898 +). The registration number on this jar label is 1898.11.28.1–4 and +four specimens +are preserved. There is also another indication arising from (L.A. Borradaile det 1/15), “ + +Metapenaeus + +n. sp. +Redet. Burkenroad 1938”, but no trace of this taxon has to date been found. Also, squeezed in above +Anchistes +is, “1 + +Upogebia +See + +1977.178.” In the Zoological Accessions, Crustacea Register, the entry for accessions number 1977.178 reads, “ + +Upogebia carinicauda +(Stimpson) + +, Kosichang, Gulf of +Siam +, coll. + pres. S.S. Flower, det. N. Ngoc-Ho”. These data sets suggest the original marine and freshwater crustacean specimens collected by Flower were not well labelled or were mixed up by later workers. + + +Moreover, while the external label on the bottle says “1898.11, +Penang +, S.S. Flower Esq”, there is a field note inside the jar that on one side is written “7 crabs” and on the other side “ +PENANG +. 2000’ +March 1898 +. S.S. Flower.” There were four crab specimens inside, which are presently identified as + +Stoliczia stoliczkana + +. This species was described by +Wood-Mason (1871) +from +Penang +and is now regarded as an endemic species on the island occurring in many fast-flowing forest and hill streams (see +Ng, 1988 +, 1992). The + +S +. +stoliczkana + +species-group has been revised by Ng (1992). There is one small juvenile specimen (ex. NHM +1898.11.28 +, now re-registered as NHM 2022.157) collected by Capt. S.S. Flower, which was difficult to identify with certainty. It, however, agrees well with many smaller ZRC specimens from various +Penang +sites that were examined for this study. Furthermore, this is the only known + +Stoliczia +species + +on +Penang +. The absence of a flagellum on the exopod of the third maxilliped is a character present even in small + +S. stoliczkana + +specimens. The other three of the seven crabs inside the bottle collected by S.S. Flower from +Penang +in +March 1898 +are presently referred to + +Geosesarma penangense +(Nobili, 1903) + +and are now re-registered as NHM 2022.912–914. + + + + \ No newline at end of file diff --git a/data/03/C3/55/03C35504FF9FFFDB5461FE040BFDFC10.xml b/data/03/C3/55/03C35504FF9FFFDB5461FE040BFDFC10.xml new file mode 100644 index 00000000000..1413d98b47f --- /dev/null +++ b/data/03/C3/55/03C35504FF9FFFDB5461FE040BFDFC10.xml @@ -0,0 +1,139 @@ + + + +Historical notes on various collectors of unidentified freshwater crabs (Crustacea: Decapoda: Brachyura) from the Malay Peninsula and Borneo, with descriptions of two new species of Isolapotamon Bott, 1968 Potamidae) + + + +Author + +Ng, Peter K.

The species epithet, + +sakon + +, is used as a noun in apposition. + + + + +Remarks. +In the sole specimen of + +Setosamon sakon + +, +new species +, the third maxilliped apparently lacks the distinctive long and coarse setae found in other + +Setosamon +species. + +Nonetheless, numerous large, deep pits that mark the attachment points of these coarse setae are scattered across the surfaces of ischium, merus, and exopod ( +Fig. 3E +), suggesting the presence of setae in the intact specimen in life. We presume that the setae were artificially detached at some point post-mortem, perhaps due to old age or improper preservation and/or handling. Furthermore, + +Setosamon sakon + +, +new species +, also displays these other characters that warrant its inclusion in the genus, namely, the almost confluent epigastric cristae and postorbital cristae; smooth dorsal carapace surface except for the slightly rugose branchial region; long third maxilliped exopod flagellum, exceeding width of merus; broadly triangular male pleon barely reaching imaginary line joining posterior edge of cheliped coxa; ambulatory legs carpi, propodi, and dactyli lined with coarse setae; and relatively short, subcylindrical G1 terminal segment, with distinct dorsal groove for the G2, broad, rounded tip, with well developed, swollen, broad dorsal flap ( +Figs. 1A–D, F +, +2A +, +3B, E +, +4B +). + + + +Setosamon sakon + +most closely resembles + +S. ubon +( +Ng & Naiyanetr, 1993 +) + +in its slightly serrated carapace anterolateral margins, slightly inflated branchial regions, and the dorsal and subdistal position of the opening of the G1 terminal segment ( +Figs. 1A–D +, +2A, B +; +Ng & Naiyanetr, 1993 +: fig. 40D). There are, however, some significant differences in the G1 structure that separate the two species, namely, the G1 terminal segment is less strongly bent outwards (versus more strongly bent outwards in + +S. ubon + +); and the G1 terminal segment dorsal flap extends along the entire length of the terminal segment, with the flap’s apex in the median portion (versus dorsal flap extending distal two-thirds length of terminal segment, with flap apex skewed towards distal portion, at the distal third in + +S. ubon + +) ( +Fig. 1A–D +; +Ng & Naiyanetr, 1993 +: fig. 40B–E). + + + +Setosamon sakon + +can be easily distinguished from + +S. somchaii +( +Ng & Naiyanetr, 1993 +) + +by the weakly serrated carapace anterolateral margin (versus carapace anterolateral margin almost entire); G1 more stout, less sinuous (versus G1 appearing more slender, sinuous); and G1 terminal segment with dorsal subdistal opening, dorsal flap with broadly convex apex (versus G1 terminal segment lacking dorsal subdistal opening, dorsal flap with broad bluntly angular apex) ( +Figs. 1A–D +, +2B +, +3A +; +Ng & Naiyanetr, 1993 +: figs. 7A, B, 41B–E). + + +Habitat. +Habitat notes were not available with the specimen; however, the sole specimen of + +Setosamon sakon + +was obtained from Phu Phan National Park in +Sakon Nakhon Province +, northeastern +Thailand +, and Phu Phan National Park is dominated by a limestone mountain range, dry evergreen forests, and is the source of numerous streams and waterfalls ( +Department of National Parks, 2015 +). The general morphology of + +Setosamon sakon + +, including the relatively low carapace, relatively stout ambulatory legs, and third maxilliped with elongated flagellum, is often associated with species with generally aquatic habits (as opposed to terrestrial or semi-terrestrial) that occur in fast-flowing hill/ montane streams ( +Ng & Naiyanetr, 1993 +; Yeo et al., 1999; +Yeo, 2000 +; +Naruse et al., 2011 +). Future expeditions are needed, however, to verify these potential associations and better understand the ecology and distribution of this crab. + + + + \ No newline at end of file diff --git a/data/03/CE/87/03CE8781D1285A6C8C4B508290FA4C6E.xml b/data/03/CE/87/03CE8781D1285A6C8C4B508290FA4C6E.xml new file mode 100644 index 00000000000..6319e2454d0 --- /dev/null +++ b/data/03/CE/87/03CE8781D1285A6C8C4B508290FA4C6E.xml @@ -0,0 +1,177 @@ + + + +Description of a new species of Setosamon Yeo & Ng, 2007 (Decapoda: Brachyura: Potamidae) from Sakon Nakhon Province, northeastern Thailand + + + +Author + +Tan, Zhi Wan + + + +Author + +, Jose Christopher E.

Shell surface with broad radial ribs crossed by irregularly spaced major commarginal lines interspersed with fine, closely spaced minor commarginal lines. Radial ribs number about 26 dorsal to keel, sometimes bifurcating towards the shell margins; finer, closely set ribs are present ventral to the keel, becoming obsolete towards the anterior, but reappearing again at the anterior end as broad but closely spaced radial ribs. Umbones subterminal. Periostracum green at the posterior half of the shell and along the posterior valve margins, while the anterior half of the shell is dark brown. Byssal hairs absent. Interior of shell tinged with purple; inside margins of dorsal and anterior regions crenulate, which correspond to the terminations of the radial ribs on the shell surface. The ligament is robust, relatively wide, resilium pits absent. The inside shell margins immediately posterior to the ligament bears about 10 crenules, whilst those at the anterior margin ventral to the umbones has 17 strongly impressed denticles that become smaller towards the posterior. The anterior adductor muscle scar traces a shallow arc just inside the antero-ventral edge of the shell. The posterior adductor muscle scar is relatively large, ovatecircular in shape (diameter about +2.7 mm +) and is conjoined with the broadly elongate posterior byssal and foot retractor muscle scar that extends about ¼ way along the length of the ligament. In addition, a series of small circular attachment scars (about +25 in +total, but not always visible) occurs along the inside shell surface of the keel from the posterior mantle attachment towards the anterior, ending at the mid-region of the shell. Shell microstructure comprising a thin (10–15µm) subperiostracal homogeneous layer and thicker 250–300 µm nacreous layer. A simple prismatic myostracum occurs as the innermost layer. Shell is predominantly aragonitic (98.8% w/w) with presence of trace amounts of calcite (0.8%). Animal with very short labial palps (about ¼ length of ctenidium) with about 22 folds. Upper edges of the ascending lamellae of outer demibranchs attached to the inside surface of mantle about ⅔ way dorsally. Upper edges of ascending lamellae of inner demibranchs attached to roof of mantle cavity. Plicate glands absent. Foot elongate, muscular. The posterior pedal/byssal retractor muscle complex is distinctly separated into two regions, comprising an anterior set that is barely split into two equal bundles near the shell attachment region, and a posterior set with two equally elongate bundles that is each subdivided into two smaller bundles at the attachment region. The pericardium is located between the anterior and posterior sets of the posterior byssal retractor muscle complex (Category 3 of +Morton, 2015 +). Midgut and style sac separate.

In the latter species, radial ribs are present but are weak and generally flattened. The prominent radial sculpture in + +P. amnicus + +is reminiscent of many marine + +Brachidontes +species + +often found intertidally on seashores around the world. However, apart from their convergence in shell sculpture, + +P. amnicus + +can be easily distinguished from true + +Brachidontes +species + +in having the terminal edges of the ascending lamella of its outer demibranch attached to the mantle lobe. As far as we are aware, the ascending lamellae of the outer demibranchs of + +Brachidontes +species + +are free and not attached to the mantle surface. The disparate positions of the two genera in phylogenetic trees based on multiple genes (see + +Fig. +1 + +in +Tan et al., 2023 +) also attest to their evolutionary divergence. + + + + \ No newline at end of file diff --git a/data/03/DC/87/03DC87884D17464E54F3FAE823C87EF2.xml b/data/03/DC/87/03DC87884D17464E54F3FAE823C87EF2.xml new file mode 100644 index 00000000000..f38e6e3fe23 --- /dev/null +++ b/data/03/DC/87/03DC87884D17464E54F3FAE823C87EF2.xml @@ -0,0 +1,130 @@ + + + +Validation of Parabrachidontes, a new genus of fresh- and brackish-water mussels (Bivalvia: Mytilidae) from Southeast Asia with a redescription of the type species and P. amnicus Tan et al., 2023 + + + +Author + +Tan, Koh Siang + + + +Author + +, Samuel Hui Ming Tan + + + +Author + +, Kitithorn Sanpanich + + + +Author + +, Teerapong Duangdee + + + +Author + +Ambarwati, + + + +Author + +Reni + +text + + +Raffles Bulletin of Zoology + + +2024 + +2024-08-01 + + +72 + + +214 +218 + + + +journal article +10.26107/RBZ-2024-0018 +2345-7600 +13256991 +313B15C1-4865-4746-8186-CD8FF4EF1D50 + + + + + + + +Parabrachidontes +Tan, Tan, Sanpanich, Duangdee & Ambarwati + +, +new genus + + + + + + +Type +species: + +Modiola leucosticta +von Martens, 1897: 86–88 + +(see below); by present designation. + + +ZooBank registration: + +urn:lsid:zoobank.org:act: +EB33F9A1- 3627-4E3D-A639-7D1A921CF36F + +and + +urn:lsid:zoobank. org:act: +7DA9F849-ED7E-429E-A0C9-DAF3FFD9D7C8 + + + + + +Diagnosis +.

The four fine, but distinct bristles at the base of the mid femur were overlooked in the new species. The species became apparent only when +3 specimens +originally identified as + +T. simplex + +appeared in a different NGS barcode cluster which was confirmed morphologically. + +T. simplex + +sp. nov. +has completely black fore coxae and no bristles at the base of the mid femur. The tip of the postpedicel has a brown rim in lateral view in + +T. simplex + +sp. nov. +, while the postpedicel is completely yellow in + +T. puniamoorthyae + +sp. nov. +Both species are sympatric. + + + +T. puniamoorthyae + +sp. nov. +is also very similar to + +T. peninsularis +Parent, 1935 + +. The latter with a body size of only +2 mm +is even smaller than + +T. puniamoorthyae + +sp. nov. +It has also all apical tarsomeres brown, but the tarsomere 1 (protarse of +Parent, 1935 +) of the fore leg is as long as following tarsomeres together and the fore tarsus is longer than the fore tibia. In + +T. puniamoorthyae + +sp. nov. +tarsomere 1 is shorter than the following tarsomeres together and the fore tarsus is as long as the fore tibia. Mid tarsomere +1 in + +T. peninsularis + +is also as long as the following tarsomeres, but shorter in + +T. puniamoorthyae + +sp. nov. +The most distinctive feature is the presence of a number of long ventral bristles at the base of the mid femur.

His description was based on a male of +9 mm +body length, with figures of a lateral view, mandibular palp, maxilliped, gnathopods 1 and 2, and abdomen. This specimen was then redescribed in +Mayer (1903) +. In +Mayer (1898) +, female specimens were collected but none were described. McCain &Steinberg (1970) mentioned the location of the type material for + +Metaprotella sandalensis + +as Universitetets Zoologiske Museum (= Zoologisk Museum), Copenhagen, while Zoologisch Museum, Amsterdam has varietal types. The Zoologisk Museum, however, possesses the types of + +Metaprotella sandalensis singaporensis +, + +but not those of + +Metaprotella sandalensis + +(N. L. Bruce, pers. comm.). This situation suggests the possibility that other institution(s) might possess the types of + +Metaprotella sandalensis +, + +and as such, we prefer not to designate a +neotype +from the present material until the status of the type material is ascertained. + + +The redescription of a male specimen from the present study closely resembles the original description by +Mayer (1898) +in the following characteristics: body somites of our specimen possess a slight concave area between head and pereonite 1 representing the presence of a vestigial suture; antenna 1 very long, nearly as long as body length; peduncular article 1–3 longer than half of the body length, article 3 longer than article +2 in +larger male (> ca. 6.0 mm in body length); a pair of anterodorsally curved projections on the head; a subtriangular lateral projection below the eye at the point of insertion of the mandibles; pereonite 2 and 3 each with a pair of anteriorly curved mid-dorsal projections and an unpaired dorsodistal projection. As shown in +Fig. 7 +, the length of antenna 1 is about 0.6 to 0.8 times the body length in both sexes. Apart from that, specimens of both sexes also have a projection positioned latero-ventrally near the anterior margin of pereonite 2. + +Similarities in mouthparts are also apparent, specifically: 1) mandibular palp with setal formula of 1-8 or more-2-1; and 2) maxilliped palp article 3 with an inwardly directed large triangular distal projection. + +Gnathopods 1 and 2 of the present study are largely similar in shape and form to +Mayer’s (1898) +description; however, slight differences do occur in setae density in gnathopod 1, with the present specimen slightly more setose in the carpus and propodus region than +Mayer’s (1898) +. In both this study and +Mayer (1898) +, gnathopod 2 palm is armed with serratiform teeth (blunt teeth) between grasping proximal and mid-palmar projection. However, our specimens have a basis with an acute anterodistal projection (not shown in +Mayer [1898] +). Pereopods 3 and 4 are also similar; slender and are half or nearly half of gill length. + + +Mayer’s (1898) +description of the male abdomen is similar to ours, with two pairs of uropods, with uropod 1 uniramus and uropod 2 ramus, very vestigial and difficult to distinguish from the abdomen. Thus, our male specimen agrees well with the original description of +Mayer (1898) +, except for a few minor differences, such as the presence of a single projection positioned latero-ventrally near the anterior margin of pereonite 2 (paired projection otherwise known as robust spines in +Mayer [1898] +) and pereopods 3 and 4 with three long and two short setae (one long and six short setae in +Mayer [1898] +). Apart from that, pereopods 5–7 of the present study were not compared, as figures were not provided in +Mayer (1898) +. + + +Currently, the following descriptions represent the recent literature on + +Metaprotella sandalensis +Mayer, 1898 + +; +Utinomi (1973) +and +Arimoto (1976) +from +Japan +, +Müller (1990) +from +French Polynesia +, +Laubitz (1991) +from +Indonesia +and +Philippines +, +Guerra-García (2003a) +from +Papua New Guinea +, +Guerra-García (2003b) +from +Mauritius +, +Guerra-García (2004a) +from Western Australia and Northern Territory, +Guerra-García (2004b) +from +Phuket +, +Thailand +, +Krapp-Schickel & Guerra-García (2005) +from +Indonesia +, and +Guerra-García (2006) +and Guerra-García & Lowry (2009) from the Great Barrier Reef and adjacent localities. + + +Of these studies, +Müller’s (1990) +and +Laubitz’s (1991) +descriptions are the most similar to ours and +Mayer’s (1898) +in the characteristics mentioned above. +Laubitz’s (1991) +figures and descriptions show strong similarity to +Mayer’s (1898) +figures and agree well with the present illustrations. The only differences were the presence of a projection found posterior to the gnathopod 2 attachment (not found in +Mayer [1898] +and +Müller [1990] +) and the length ratio of antenna 1 peduncular article 2 and 3. +Mayer (1898) +, +Müller (1990) +, and the present study have peduncular article 2 slightly shorter than article 3 (~0.8× shorter) whilst Laubitz’s figure shows article 2 longer than article 3 (~1.7× longer). There were also minor differences in certain appendages in +Müller (1990) +, such as, antenna 1; proximal article of flagellum is composed of two articles as compared to three articles in our study. + + + +Fig. 6. + +Metaprotella sandalensis + +, female, 5.03 mm, AM P.87576, Pointe de Easo (= Easho), Baie de Sandal, Lifou Island. Scales for ABD (L) and ABD (V) represent 0.05 mm; P3, P4, P5, P6, and P7 represent 0.1 mm. + + + +However, the similarity of other descriptions, such as +Guerra-García (2003a +, +2004a +, +2006 +), +Krapp-Schickel & Guerra-García (2005) +, and Guerra-García & Lowry (2009), to ours and +Mayer’s (1898) +is questionable. Most of these studies ( +Guerra-García, 2004a +, +2006 +; +Krapp-Schickel & Guerra-García, 2005 +; Guerra-García & Lowry, 2009) share one common characteristic; the length of male antenna 1 being shorter than those of the present study (see +Fig. 7 +); <3/5 +th +of the body length. The body lengths reported in these five studies were between +6.5 to 9.4 mm +, which overlaps with large males of our study having longer antenna 1. Moreover, most of the appendages and mouthparts were not described and/or figures were not provided. Based on whole body figures provided in these five studies, only +Krapp-Schickel & Guerra-García (2005) +reported Indonesian specimens with a subtriangular lateral projection below the eye, while the other four are either not drawn or absent. In addition, the palmar margin of gnathopod 2 for these four is also difficult to ascertain (distal shelf with 1–2 triangular projections). Guerra-García & Lowry (2009) also mentioned the setal formula of the mandibular palp as (1-x-1) in the description as compared to 1-x-y- +1 in +both our study and +Mayer’s (1898) +. Although the male of +Guerra-García (2003a) +from +Papua New Guinea +possesses a relatively longer antenna 1 (ca. 4/5 +th +of body length) its head lacks a subtriangular lateral projection below the eye. + + + +Metaprotella sandalensis + +from +Utinomi (1973) +and +Arimoto (1976) +from +Japan +, and +Guerra-García (2003b +, +2004b +), from +Mauritius +and +Thailand +, respectively, clearly differs from + +M. sandalensis + +of this study and +Mayer’s (1898) +. This may be explained by +Japan +and +Mauritius +being at the extremes of the distribution thus far reported. + + +Utinomi (1973) +described specimens collected from Shirahama, Kii Peninsula, central +Japan +. +Arimoto (1976) +cited the descriptions and figures of +Utinomi (1973) +in the monograph of the +Caprellidae +of +Japan +. +Utinomi’s (1973) +description differs from ours and +Mayer’s (1898) +in the absence of a subtriangular lateral projection below the eye, absence of an anterior lateral projection on pereonite 2, subequal length of pereonites 4 and 5, oval-shaped gills instead of elongated, setal formula of the mandibular palp (1-x-1) as compared to 1-x-y-1 and tuff of minute setae on distal margin of uropod 1 ramus instead of normal setae. + + + +Metaprotella sandalensis + +collected from +Mauritius +( +Guerra-García, 2003b +) differs from the present study and +Mayer’s (1898) +in its more prominent suture, the absence of a subtriangular lateral projection below the eye, the absence of an anterior lateral projection on pereonite 2, the length ratio of pereopod 3 or 4 to gill (1/4 of gill as compared to 1/3 of gill in our study) and very short peduncular article 3 of antenna 1 (0.4× the length of article 2 as compared to 1.1× the length of article +2 in +our study). +Krapp-Schickel & Guerra-García (2005) +suggests that + +M. sandalensis + +from +Mauritius +might be an unknown species close to + +Metaprotella africana +Mayer, 1903 + +recorded from +Djibouti +in the Gulf of Aden, northwest Indian Ocean. + + +Material examined by +Guerra-García (2004b) +from +Phuket +is similar to ours in the longer peduncular article 3 of antenna 1 (1.3× longer than article 2) and arrangement of the dorsal projections, but differs in the presence of an extra subtriangular lateral projection situated postero-ventrally on the head; a paired projection positioned latero-ventrally near the anterior margin of pereonite 2 (also found in +Mayer [1898] +); its subequal length of pereonites 4 and 5; tuff of minute setae on distal margin of uropod 1 ramus (five normal setae along outer margin in the present study); palmar margin of gnathopod 2 with a long narrow proximal projection provided with a very short robust setae (grasping spine) almost like a stub, mid-palmar projection also very narrow and elongated and absence of a well developed distal shelf ( +Fig. 5C +in +Guerra-García [2004b] +). According to +Guerra-García (2004b) +, differences in the structure of gnathopod 2 (shown in +Figs. 5C, 5D +) were due to different growth stages. Gnathopod 2 of +Fig. 5D +is closer to our study and +Mayer’s (1898) +. However, +Fig. 5C +appears to be very different. Considering all these differences, we feel that the specimen from +Guerra-García (2004b) +is unique and distinctively different from the present study and +Mayer (1898) +. + + + +Fig. 7. The relationship between antenna 1 length and body length of + +Metaprotella sandalensis + +collected from coastal areas of Lifou Island. + + + +In conclusion, the descriptions and figures of +Müller (1990) +and +Laubitz (1991) +on + +Metaprotella sandalensis + +, one of the dominant species of the Caprellidea in the tropical west Pacific coasts, are most similar to ours and +Mayer’s (1898) +. Conversely, descriptions by +Guerra-García (2003b +, +2004b +), respectively from +Mauritius +and +Thailand +, as well as +Utinomi (1973) +and +Arimoto (1976) +from +Japan +are clearly different from the + +M. sandalensis + +of this study and +Mayer’s (1898) +. + +M. sandalensis + +in +Guerra-García (2003a +, +2004a +, +2006 +), +Krapp-Schickel & Guerra-García (2005) +, and Guerra-García & Lowry (2009) is reported based on lateral view figures of the species. Detailed descriptions of corresponding specimens in the above studies would help to clarify the status of the complex. There are indications that the distribution of + +M. sandalensis + +is more limited than previously thought. The present comparison suggests that further taxonomic studies on this species group are necessary. Detailed drawings and descriptions provided in this study could aid in eliminating further confusion within the + +M. sandalensis + +complex, including subspecies described by +Mayer (1903) +and +Schellenberg (1938) +, and thus establish its definitive characteristics. + + + + + +Distribution +. + +— Lifou Island, +Loyalty Islands +, +New Caledonia +( +Mayer, 1898 +); +Indonesia +, +Philippines +, ( +Laubitz, 1991 +); Bora Bora and Morea, Society Islands ( +Müller, 1990 +). + + + + \ No newline at end of file diff --git a/data/43/7B/87/437B87F6962FFFD1E9059B8BAE05FD1E.xml b/data/43/7B/87/437B87F6962FFFD1E9059B8BAE05FD1E.xml new file mode 100644 index 00000000000..bafbcd9739b --- /dev/null +++ b/data/43/7B/87/437B87F6962FFFD1E9059B8BAE05FD1E.xml @@ -0,0 +1,316 @@ + + + +Leocrates bitungensis (Hesionidae, Annelida): a new polychaete species from North Sulawesi, Indonesia + + + +Author + +Pamungkas, Joko + +text + + +Raffles Bulletin of Zoology + + +2024 + +2024-07-26 + + +72 + + +194 +202 + + + +journal article +10.26107/RBZ-2024-0016 +2345-7600 +13256956 +E854C045-0226-4A51-BC8E-D1F28AE638F3 + + + + + + + +Leocrates bitungensis + +, +new species + + + + + + +( +Figs. 2–4 +) + + + + +Material examined. + +Holotype +: 1 ( +MZB +.

External surface of RV dark yellow to purplish or greyish brown, often with irregular blotches and/or one or more darker radiating bands or numerous fine streaks, with overlapping thin, flaky foliose commarginal edges. Interior surface of valves generally white with a slight pearly sheen, with or without varying degrees of discoloured pink and greenish patches or purplish brown blotches that may become dominant in some specimens, and often with white calcareous patches. Interior margin of RV often with narrow yellowish-brown border that is broadest ventrally. Umbonal cavity of LV usually shallow, sometimes absent or indistinguishable. The kidney-shaped adductor muscle scar is brownish grey to nearly black, usually similar in colouration in both valves, but may occasionally be darker in one valve than the other. + + +Body. +Living animals with mantle edges coloured brown to dark brown; visceral mass yellowish brown. Mantle edge outermost layer smooth, tentacles absent; outside wall not pigmented, inside wall with faint black surface pigment. Mantle edge middle layer with tentacles along entire edge; tentacles are variable in size, with larger tentacles slightly offset from edge and originates from side of wall facing the innermost layer. Outside wall of middle layer not pigmented, while the inside wall is heavily pigmented black. Mantle edge innermost layer with black dimorphic tentacles that become smaller, spaced farther apart and less black dorsally. Mantle surface colouration over visceral mass dark yellow to brown. + + +Habitat. +On bark of mangrove trees, intertidal jetty pilings and seawalls, as well as on sloping walls of tidal canals. + + + + +Remarks. +This large species has often been referred to as the junior subjective synonym + +Crassostrea iredalei + +(now + +M. iredalei + +) in oyster aquaculture literature (e.g., +Poutiers, 1998 +). The contrasting dark muscle scar colouration against the otherwise white interior is characteristic and appears to be reliable for distinguishing this species from + +M +. +belcheri + +.

Spire-whorls ovoidconical with a deep suture; apex pointed; penultimate whorl widest in frontal view, or last and penultimate whorls of comparable width. Whorls 6.75–7; protoconch-teleoconch boundary not clearly visible; all whorls strongly convex (bulging); first juvenile peristome developed at ca. 2 whorls; last juvenile peristome present ca. 2 whorls behind adult peristome. Protoconch glossy, smooth. Teleoconch also glossy and smooth, without ribs, except for a few riblets behind each juvenile peristome. Detached part ( +“tuba +”) with fine, low ribs, and with short ribs around the umbilicus, not reaching the middle of the body whorl; this fine ribbing is recognisable a bit higher up, but gradually weakens towards penultimate whorl. Last ca. 0.25 whorls detached, detached part thick, aperture not or slightly protruding beyond spire-whorl plane; detached portion slopes downward at an angle of about 40°; upper suture continues on detached part as blunt, finely ribbed keel, and extends to back side of sinulus, bearing a shallow groove on inner side; this groove divides the upper part of the detached portion in the middle. Outer (lateral) side of detached portion without groove, but with a slight depression corresponding with the lower palatal tooth; lower suture continues towards the peristome without forming a keel, with a short, shallow groove on the umbilical side until a swelling that is situated behind and parallel with the peristome. Aperture axis slightly oblique to shell axis; aperture ovoid with a narrow, strongly isolated sinulus. Sinulus opens slightly upwards. Parieto-angular lamella very strongly developed, long, outer tip slightly protruding and slightly bent towards palatal lip, inner central portion of parieto-angular lamella slightly turns in the other (columellar) direction. Upper palatal tooth blunt, but strong, lower palatal tooth situated much deeper and lower in position, more pointed than upper palatal tooth. Columellar lamella denticle-like, not elongated, rather pointed, situated deep inside the aperture, its position corresponds with the end of the groove on the umbilical side of the tuba. Peristome thickened, strongly expanded (except for the sinulus area), its margin slightly reflected. Umbilicus closed. + + +Juvenile aperture. +Juveniles of 3–4.5 whorls have four apertural barriers: parieto-angular lamella, upper palatal tooth, lower palatal tooth, columellar lamella.

Nevertheless, acute, corneous-tipped spines on the right chela, the absence of additional dorsal spines or spinules on the carpi of the second pereopods, and the possession of two rows of corneous scales in the propodal rasp of the fourth pereopod immediately distinguish + +P. similis + +, +new species +, from those four species. In those four species, the armature on the dorsal surface of the right palm consists of blunt tubercles ( + +P. bellula + +and + +P. vicina + +) or subacute, non-corneous-tipped spines ( + +P. furusei + +and + +P. laevispinosa + +); the carpi of the second pereopods bear one to three dorsal spines or spinules in addition to the dorsodistal spine; and the propodal rasp of the fourth pereopod consists only of a partial row of corneous scales. Furthermore, the absence of a longitudinal groove on the right chela adjacent to the dorsolateral margin differentiates the new species from + +P. bellula + +, + +P. laevispinosa + +, and + +P. vicina + +. + + +In having a spinose chela of the left cheliped, + +P. rahayuae + +is also comparable with the present new species and the four above mentioned species. However, + +P. rahayuae + +is immediately distinguished from the present new species in having blunt, various-sized tubercles on the right chela and the possession of a dorsal row of strong spines on the carpi of the second pereopods. + + +As only +one male +specimen is present, it is not clear if the lack of the fourth pleopod is normal or aberrant. Nevertheless, it is possible that the missing pleopod is a result of damage or poor preservation condition of the specimen. + + + + +Fig. 5. + +Pylopaguropsis similis + +, +new species +, holotype, fmale (sl 4.3 mm), PANGLAO 2004, Balicasag, NMCR.
