-Description
-
-
-
-Carapace (
-Figs 1A
-,
-5B
-) approximately circular to oval, slightly broader than long; dorsal carapace surface slightly concave, not strongly outlined by grooves, only with well defined gastrocardiac and thoracic grooves, approaching but not reaching antero- and posterolateral margins, respectively; no row of setae along lateral margins, except for some regularly mid-spaced setae in males; carapace angles not well marked. Anterolateral margin entire, without crenulations, lobes or teeth. Branchiostegite only weakly visible dorsally.
-
-
-Eyes visible dorsally. Antennules (
-Fig. 1B
-) obliquely folded along hollowed ventral parts of rostrum and entirely hidden dorsally. Antennae well separated from antennules, at least at their bases; urinary article at level of epistome. Rostrum (
-Figs 1
-,
-4
-,
-5
-B–D) broadly rounded, spade-shaped, barely deflexed; dorsal surface spatulate with marked depression; carapace rim as a small ridge continuous across behind rostrum. Proepistome represented by triangular ventral expansion of rostrum (
-Fig. 1B
-). Epistome moderately developed; anterior margin undulated. Lower orbital margin with one conspicuous knob, not visible dorsally. Pterygostomial regions with setae, distinctly separated from subhepatic area by marked ridge. Mxp3 moderately gaping, broad; merus and ischium broad, short; midlength of merus slightly longer than that of ischium (
-Figs 1B
-,
-2B
-). Sternum/pterygostome junction substantially developed due to extension of sternite 4. Milne-Edwards openings separated from chelipeds.
-
-
-Male chelipeds much stouter than walking legs, particularly in large males (
-Fig. 4
-); merus and carpus with stiff, regularly spaced setae; propodus very inflated, covered with long soft setae partially extending on fingers; fingers with finely denticulate cutting edges, not gaping. Female chelipeds narrow, propodus moderately inflated, devoid of long setae; fingers proportionally rather long, with with finely denticulate cutting edges completely joined. Walking legs proportionally rather long, with margins bearing stiff, regularly spaced, scattered setae; dactyli slender but not distinctly longer than respective propodi, smoothly curved, setose, without teeth, ending in pointed tip.

-Thoracic sternum of male (
-Fig. 2A
-) with sternites 4–8 considerably enlarged, with suture 4/5 to 7/8 laterally confined. Sternites 1 and 2 not separated by suture but their demarcation visible on lateral margins; sternite 2 separated from sternite 3 by complete suture; sternite 3 as narrow pentagonal band; suture 3/4 tiny, only lateral, just at level of extension of sternite 4. No longitudinal line. Paired branchiosternal canal apertures located posterolaterally on sternite 8, concealed by pleon (
-Fig. 3A
-).
-
-
-Sternopleonal cavity of male short, triangular, deep (
-Fig. 2C
-). Pleons in both sexes (
-Figs 2A
-,
-3B
-) without fused somites, except 6 fused to telson, thus five somites plus pleotelson. Male pleon widely triangular, regularly widening from base to pleotelson; pleotelson widely triangular, somewhat trilobed, with intercalated plates partially delineated, salient and visible laterally at base, partially included. Pressbutton on lateral side of sternopleonal cavity (
-Fig. 2C
-). Male gonopore sternal.
-
-
-Female pleon (

-A–B) oval to expanded in ovigerous females. Female pleopods 2–5 biramous. Ovigerous females with very few and large eggs measuring
-0.96 mm
-in diameter (
-Fig. 3A
-). Vulvae located on undivided portion of thoracic sternum corresponding to sternite 6, thus not deplaced anteriorly. First gonopods stout, practically filling most of sternopleonal cavity (

-Distribution
-
-
-
-
-Richerius marqueti
-
-gen. et sp. nov.
-is exclusively known from freshwaters in small flowing streams where it lives among the aquatic vegetation (
-Fig. 5A
-). It is found at an altitude of up
-500 m
-, therefore further from the sea than
-
-Odiomaris pilosus
-
-(that is usually encountered in the lower course of rivers). By comparison,
-
-Amarinus lacustris
-(Chilton, 1882)
-
-has been reported from
-New Zealand
-freshwaters from Lord Howe Island at altitudes between
-61–92 m
-(
-
-Etheridge
-1889
-
-) and even about
-800–900 m
-(
-
-Chilton
-1915
-
-;
-
-Holthuis
-1968
-
-);
-
-A. angelicus
-Holthuis, 1968
-
-, from the central mountain range of
-Papua New Guinea
-, was collected in pure freshwater of a watercress swamp at an altitude of
-1600 m
-(
-
-Holthuis

-
-,

-1982

-
-
-Remarks
-
-
-
-The subfamily
-Odiomarinae
-was erected by
-Guinot (2011a)
-to receive two genera of the family
-Hymenosomatidae
-characterised by the presence on the male pleon of intercalated platelets, either articulated and moveable (
-Guinot 2011a
-: fig. 2) or relatively less well-demarcated:
-
-Odiomaris
-Ng & Richer de Forges, 1996
-
-, endemic to
-New Caledonia
-, and
-Amarinu
-(at least
-pro parte
-), mostly from fresh and estuarine waters of the Indo-West Pacific region.
-Richeriu
-s gen. nov. shows several plesiomorphic characters that include the male and female pleons without fused somites (except for pleotelson), thus consisting of six elements (namely the maximum of somites existing in
-Hymenosomatidae
-), the prominent, partially demarcated intercalated platelets, the thoracic sternum with the anterior sternites forming a small produced plate, the vulvae not anteriorly displaced, the G1 only gently curved and simple.
-
-Richerius
-
-gen. nov.
-can be assigned to the
-Odiomarinae
-.
-
-
-
-Odiomaris
-
-is known from two species: the
-type
-species
-
-Elamena pilosa
-A. Milne-Edwards, 1873
-
-, referred to as
-
-Halicarcinus
-White, 1846
-
-by
-Holthuis (1968)
-, as
-
-Amarinus
-
-by
-Lucas (1980)
-then as
-
-Odiomaris
-
-by
-Ng & Richer de Forges (1996)
-, mainly freshwater but also euryhaline; and
-
-O. estuarius
-Davie & Richer de Forges, 1996
-
-, exclusively brackish. An important difference between these two species is the rostrum: it is lowered ventrally as a triangular, V-shaped projection in
-
-O. pilosus
-
-so as to be positioned between the antennules (
-Fig. 7A
-) (A. Milne-Edwards 1873: pl. 18, fig. 6a, as
-
-Elamene pilosa
-
-;
-Ng & Richer de Forges 1996
-: fig. 6c–d), whereas it is spatulate and does not extend to form a ventral projection between the antennules in
-
-O. estuarius
-
-(
-Fig. 8
-A–B) (
-Davie & Richer de Forges 1996
-: fig. 1a–b).
-
-
-
-Richerius
-
-gen. nov.
-shares with
-
-Odiomaris
-
-the same arrangement of the cephalic appendices. But its rostrum is spatulate without folding down ventrally (
-Figs 1
-,
-4
-,
-5D
-), instead of being lowered ventrally as a V-shaped projection located between the antennules as in
-
-Odiomaris pilosus
-
-(
-Fig. 7A
-). In
-
-Richerius
-
-gen. nov.
-(
-Fig. 1B
-), the proepistome is represented by a ventral expansion of the rostrum; therefore, the antennules are located along the proepistome, whereas in
-
-Odiomaris pilosus
-
-the antennules are obliquely folded in a fossa hollowed all along with the lateral parts of the V-shaped rostrum and the eye.
-
-Richerius marqueti
-
-gen. et sp. nov.
-actually has a rostrum and proepistome more similar to those of
-
-O. estuarius
-
-(
-Fig. 8
-) (
-Davie & Richer de Forges 1996
-: fig. 1) than to those of
-
-O. pilosus
-
-. In fact, the genus-level differences between
-
-Richerius
-
-gen. nov.
-and
-
-Odiomaris
-
-remain unclear. Actually,
-
-O. estuarius
-
-seems morphologically closer to
-
-Richerius
-
-gen. nov.
-than to
-
-O. pilosus
-
-, at least in some characteristics. A possible transfer of
-
-O. estuarius
-
-to
-
-Richerius
-
-gen. nov.
-has been considered but needs to be decided later, especially when the status of
-
-Odiomaris
-aff.
-pilosus
-
-is resolved (see below, ‘Remarks on
-
-Odiomaris
-aff.
-pilosus
-
-from the Iouanga River and two other streams’).
-
-
-Along the lower orbital margin there are two salient knobs in both species of
-
-Odiomaris
-
-, both prominent in dorsal view in
-
-O. pilosus
-
-(A. Milne-Edwards 1873: pl. 18, fig. 6a;
-Ng & Richer de Forges 1996
-: fig. 6a, d, not figured in fig. 6c;
-Guinot & Richer de Forges 1997
-: figs 1a, c, 2c), but shorter and not dorsally visible in
-
-O. estuarius
-
-(
-Davie & Richer de Forges 1996
-: fig. 1a; not figured in fig. 1b). In contrast, there is only one, smaller knob in
-
-Richerius
-
-gen. nov.
-(
-Fig. 1B
-). The cheliped palm of
-
-R. marqueti
-
-gen. et sp. nov.
-is covered with long, flexible setae (
-Fig. 5
-C–D), instead of numerous spinules (or stiff setae) in
-
-O. pilosus
-
-(
-Fig. 6
-) (A. Milne-Edwards, 1873: pl. 18, fig. 6d;
-Ng & Richer de Forges 1996
-: fig. 6f), and sparse, short setae in
-
-O. estuarius
-
-(
-Fig. 8
-). In fact, the whole body (including the margins of the rostrum) and legs of
-
-O. pilosus
-
-are covered with spiniform, stiff setae that give a bristle appearance (
-Ng & Richer de Forges 1996
-: figs 5a–b, 6a, d;
-Guinot & Richer de Forges 1997
-: fig. 1a), whereas
-
-O. estuarius
-
-has a carapace with soft, short setae and legs with longer setae (
-Davie & Richer de Forges 1996
-: fig. 1a). The male cheliped fingers are practically joining in
-
-R. marqueti
-
-gen. et sp. nov.
-(
-Fig. 5C
-), but with a broad proximal gap in
-
-O. pilosus
-
-(
-Fig. 6
-A–B) (A. Milne-Edwards 1873: 322, pl. 18, fig. 6, 6d, as
-
-Elamene pilosa
-
-;
-Ng & Richer de Forges 1996
-: fig. 6f); in
-
-O. estuarius
-
-the chelae are narrower, with long fingers without marked gap (
-Fig. 8
-A–B) (
-Davie & Richer de Forges 1996
-: fig. 1). The grooves on the carapace dorsal surface are very distinct in
-
-O. pilosus
-
-, well marked in
-
-R. marqueti
-
-gen. et sp. nov.
-, whereas almost indiscernible in
-
-O. estuarius
-
-. The sterno-pleonal cavity is short in
-
-Richerius
-
-gen. nov.
-and in
-
-Odiomaris
-
-, and accordingly the pleon also. The male pleon is as a narrow triangle, with a long pleotelson in both
-
-Odiomaris
-
-species (A. Milne-Edwards 1873: pl. 18, fig. 6b, as
-
-Elamene pilosa
-
-;
-Ng & Richer de Forges 1996
-: fig. 7a–b;
-Guinot & Richer de Forges 1997
-: fig. 2a:
-
-O. pilosus
-
-;
-Davie & Richer de Forges 1996
-: fig. 2c:
-
-O. estuarius
-
-), markedly wider and with a much shorter pleotelson in
-
-R. marqueti
-
-gen. et sp. nov.
-(
-Fig. 2A
-). The intercalated platelets, which are completely demarcated and moveable in
-
-O. pilosus
-
-(
-Guinot 2011a
-: fig. 2), are only partially delineated in
-
-R. marqueti
-
-gen. et sp. nov.
-, and not detached in
-
-O. estuarius
-.
-
-The female pleon is rather similar in
-
-Richerius
-
-gen. nov.
-and
-
-Odiomaris
-
-, with five somites plus pleotelson. The G1 of
-
-Richerius
-
-gen. nov.
-(
-Fig. 2D
-) is curved at the base, otherwise with little curvature, with a terminal portion bearing fine setae and ending in one lobe without corneous process, whereas the G1 of
-
-Odiomaris
-
-is characterised by two distinct distal processes, a longer corneous process and a shorter lobular elongation of the stem (
-Fig. 7B
-:
-
-O. pilosus
-
-) (
-Ng & Richer de Forges 1996
-: fig. 7c– d:
-
-O. pilosus
-
-;
-Davie & Richer de Forges 1996
-: fig. 2c:
-
-O. estuarius
-
-).
-
-O. estuarius
-
-is a much smaller species than
-
-O. pilosus
-
-, and
-
-R. marqueti
-
-gen. et sp. nov.
-seems to be nearly as small as
-
-O. estuarius
-
-.
-
-
-The main differences to distinguish the two genera
-
-Odiomaris
-
-and
-
-Amarinus
-
-stated by
-Davie & Richer de Forges (1996: 259)
-were: 1) in
-
-Odiomaris
-
-, the G1 (see
-Fig. 7B
-) more slender, with two distinct distal processes, a longer corneous process and a shorter lobular elongation of the stem than in
-
-Amarinus
-
-; 2) in
-
-Odiomaris
-
-, the elongated triangular telson of the male pleon is significantly longer than wide at base, whereas in
-
-Amarinus
-
-the telson is more or less rounded and short, being much wider than long.
-
-
-The genus
-
-Amarinus
-Lucas, 1980
-
-(
-type
-species by original designation:
-
-Elamena lacustris
-Chilton, 1882
-
-) is known from more than ten species. They all inhabit low salinity environments, from brackish habitats to pure freshwater waters permanently (streams, lakes, swamps), and have a large distribution (
-New Zealand
-,
-Australia
-,
-Indonesia
-, the
-Philippines
-,
-Papua New Guinea
-). Cases where
-
-Amarinus
-
-has been reported from
-New Caledonia
-, as in
-Chuang & Ng (1994: 87
-, 90, table 1, under
-
-A. pilosus
-
-) and erroneously as in
-Guinot (2011a: 23)
-, are attributable to the fact that the species
-
-pilosus
-
-was previously associated with the genus
-
-Amarinus
-
-(see
-Lucas 1980
-) until
-Ng & Richer de Forges (1996)
-made it the
-type
-species of their new genus
-
-Odiomaris
-
-. So far, no species of
-Amarinu
-s has actually been reported in
-New Caledonia
-. Suspecting that our new species might belong to the genus
-
-Amarinus
-
-, we therefore carefully compared
-
-Richerius
-
-gen. nov.
-to
-
-Amarinus
-
-, and in particular to its
-type
-species,
-
-A. lacustris
-
-, another freshwater hymenosomatid.
-
-
-
-Richerius marqueti
-
-gen. et sp. nov.
-can be distinguished from
-
-Amarinus lacustris
-
-by: the wide male pleon, with prominent marks corresponding to intercalated platelets (
-Fig. 2A
-) (versus narrow and without intercalated platelets in
-
-A. lacustris
-
-, see Melrose 1975: fig.
-42g
-;
-Lucas 1980
-: fig. 7b); the G1 rather narrow and with one distal lobe without corneous process (
-Fig. 2D
-) (versus stout and without lobes, see Melrose 1975: fig. 42h–i;
-Lucas 1980
-: fig. 10e); and by the arrangement of antennules and antennae.
-
-
-In providing a key of the Southeast Asian hymenosomatids,
-Ng & Chuang (1996: 3–5
-, 6–12) have shown the presence of several groups of species within
-
-Amarinus
-
-, suggesting that the genus could be paraphyletic. Today, another problem arises, especially regarding the antennular morphology. Melrose (1975: 84, 87, figs 41–42, as
-
-Halicarcinus lacustris
-
-), who has thoroughly studied the
-type
-species
-
-A. lacustris
-
-, confined to lakes and non-tidal rivers of
-New Zealand
-and southeastern
-Australia
-, states that the antennules are “small, not visible dorsally when folded”. Her figure 41d actually seems to show a folded antennule, only with the broad basal article and the second cylindrical article, without the short, supposedly folded flagellum being seen [the frontal view of fig. 41e in Melrose (1975) shows a complete, unfolded antennule]. Our examination of
-
-Amarinus lacustris
-
-, on the other hand, reveals that both antennules and antennae are inserted very closely together at their bases and remain parallel, with both flagella visible dorsally, as represented by
-Lucas (1980
-: fig. 1d) for a generalised hymenosomatid or by Melrose (1975: fig. 43c) for
-
-Halicarinus tongi
-Melrose, 1975
-
-. In fact, if it is possible for the antennule of
-
-A. lacustris
-
-to fold itself down [but not obliquely along the rostrum as in
-
-Odiomaris
-
-(
-Fig. 7A
-), see A. Milne-Edwards 1873: pl. 18, fig. 6a], this does not correspond to the resting position. In the seven specimens of
-
-A. lacustris
-
-examined, the antennule and antenna are very closely inserted and remain parallel, both being stretched forward; the unfolded flagellum is visible dorsally in all individuals. In any event, the disposition of the antennule and antenna differs from that
-
-Odiomaris
-
-(
-Fig. 7A
-:
-
-O. pilosus
-
-) (
-Ng & Richer de Forges 1996
-: fig. 6c–d:
-
-O. pilosus
-
-).
-
-
-A picture of the cephalic region in ventral view of
-
-Amarinus angelicus
-
-(
-Holthuis 1968: 114
-, fig. 2b) shows an antennule “entirely hidden below the rostrum”, obliquely folded, which does not seem to correspond to the condition of
-

+Description
+
+
+
+Carapace (
+Figs 1A
+,
+5B
+) approximately circular to oval, slightly broader than long; dorsal carapace surface slightly concave, not strongly outlined by grooves, only with well defined gastrocardiac and thoracic grooves, approaching but not reaching antero- and posterolateral margins, respectively; no row of setae along lateral margins, except for some regularly mid-spaced setae in males; carapace angles not well marked. Anterolateral margin entire, without crenulations, lobes or teeth. Branchiostegite only weakly visible dorsally.
+
+
+Eyes visible dorsally. Antennules (
+Fig. 1B
+) obliquely folded along hollowed ventral parts of rostrum and entirely hidden dorsally. Antennae well separated from antennules, at least at their bases; urinary article at level of epistome. Rostrum (
+Figs 1
+,
+4
+,
+5
+B–D) broadly rounded, spade-shaped, barely deflexed; dorsal surface spatulate with marked depression; carapace rim as a small ridge continuous across behind rostrum. Proepistome represented by triangular ventral expansion of rostrum (
+Fig. 1B
+). Epistome moderately developed; anterior margin undulated. Lower orbital margin with one conspicuous knob, not visible dorsally. Pterygostomial regions with setae, distinctly separated from subhepatic area by marked ridge. Mxp3 moderately gaping, broad; merus and ischium broad, short; midlength of merus slightly longer than that of ischium (
+Figs 1B
+,
+2B
+). Sternum/pterygostome junction substantially developed due to extension of sternite 4. Milne-Edwards openings separated from chelipeds.
+
+
+Male chelipeds much stouter than walking legs, particularly in large males (
+Fig. 4
+); merus and carpus with stiff, regularly spaced setae; propodus very inflated, covered with long soft setae partially extending on fingers; fingers with finely denticulate cutting edges, not gaping. Female chelipeds narrow, propodus moderately inflated, devoid of long setae; fingers proportionally rather long, with with finely denticulate cutting edges completely joined. Walking legs proportionally rather long, with margins bearing stiff, regularly spaced, scattered setae; dactyli slender but not distinctly longer than respective propodi, smoothly curved, setose, without teeth, ending in pointed tip.

+Distribution
+
+
+
+
+Richerius marqueti
+
+gen. et sp. nov.
+is exclusively known from freshwaters in small flowing streams where it lives among the aquatic vegetation (
+Fig. 5A
+). It is found at an altitude of up
+500 m
+, therefore further from the sea than
+
+Odiomaris pilosus
+
+(that is usually encountered in the lower course of rivers). By comparison,
+
+Amarinus lacustris
+(Chilton, 1882)
+
+has been reported from
+New Zealand
+freshwaters from Lord Howe Island at altitudes between
+61–92 m
+(
+
+Etheridge
+1889
+
+) and even about
+800–900 m
+(
+
+Chilton
+1915
+

+Holthuis
+1968

+
+
+Remarks
+
+
+
+The subfamily
+Odiomarinae
+was erected by
+Guinot (2011a)
+to receive two genera of the family
+Hymenosomatidae
+characterised by the presence on the male pleon of intercalated platelets, either articulated and moveable (
+Guinot 2011a
+: fig. 2) or relatively less well-demarcated:
+
+Odiomaris
+Ng & Richer de Forges, 1996
+
+, endemic to
+New Caledonia
+, and
+Amarinu
+(at least
+pro parte
+), mostly from fresh and estuarine waters of the Indo-West Pacific region.
+Richeriu
+s gen. nov. shows several plesiomorphic characters that include the male and female pleons without fused somites (except for pleotelson), thus consisting of six elements (namely the maximum of somites existing in
+Hymenosomatidae
+), the prominent, partially demarcated intercalated platelets, the thoracic sternum with the anterior sternites forming a small produced plate, the vulvae not anteriorly displaced, the G1 only gently curved and simple.
+
+Richerius
+
+gen. nov.
+can be assigned to the
+Odiomarinae
+.
+
+
+
+Odiomaris
+
+is known from two species: the
+type
+species
+
+Elamena pilosa
+A. Milne-Edwards, 1873
+
+, referred to as
+
+Halicarcinus
+White, 1846
+
+by
+Holthuis (1968)
+, as
+
+Amarinus
+
+by
+Lucas (1980)
+then as
+
+Odiomaris
+
+by
+Ng & Richer de Forges (1996)
+, mainly freshwater but also euryhaline; and
+
+O. estuarius
+Davie & Richer de Forges, 1996
+
+, exclusively brackish. An important difference between these two species is the rostrum: it is lowered ventrally as a triangular, V-shaped projection in
+
+O. pilosus
+
+so as to be positioned between the antennules (
+Fig. 7A
+) (A. Milne-Edwards 1873: pl. 18, fig. 6a, as
+
+Elamene pilosa
+
+;
+Ng & Richer de Forges 1996
+: fig. 6c–d), whereas it is spatulate and does not extend to form a ventral projection between the antennules in
+
+O. estuarius
+
+(
+Fig. 8
+A–B) (
+Davie & Richer de Forges 1996
+: fig. 1a–b).
+
+
+
+Richerius
+
+gen. nov.
+shares with
+
+Odiomaris
+
+the same arrangement of the cephalic appendices. But its rostrum is spatulate without folding down ventrally (
+Figs 1
+,
+4
+,
+5D
+), instead of being lowered ventrally as a V-shaped projection located between the antennules as in
+
+Odiomaris pilosus
+
+(
+Fig. 7A
+). In
+
+Richerius
+
+gen. nov.
+(
+Fig. 1B
+), the proepistome is represented by a ventral expansion of the rostrum; therefore, the antennules are located along the proepistome, whereas in
+
+Odiomaris pilosus
+
+the antennules are obliquely folded in a fossa hollowed all along with the lateral parts of the V-shaped rostrum and the eye.
+
+Richerius marqueti
+
+gen. et sp. nov.
+actually has a rostrum and proepistome more similar to those of
+
+O. estuarius
+
+(
+Fig. 8
+) (
+Davie & Richer de Forges 1996
+: fig. 1) than to those of
+
+O. pilosus
+
+. In fact, the genus-level differences between
+
+Richerius
+
+gen. nov.
+and
+
+Odiomaris
+
+remain unclear. Actually,
+
+O. estuarius
+
+seems morphologically closer to
+
+Richerius
+
+gen. nov.
+than to
+
+O. pilosus
+
+, at least in some characteristics. A possible transfer of
+
+O. estuarius
+
+to
+
+Richerius
+
+gen. nov.
+has been considered but needs to be decided later, especially when the status of
+
+Odiomaris
+aff.
+pilosus
+
+is resolved (see below, ‘Remarks on
+
+Odiomaris
+aff.
+pilosus
+
+from the Iouanga River and two other streams’).
+
+
+Along the lower orbital margin there are two salient knobs in both species of
+
+Odiomaris
+
+, both prominent in dorsal view in
+
+O. pilosus
+
+(A. Milne-Edwards 1873: pl. 18, fig. 6a;
+Ng & Richer de Forges 1996
+: fig. 6a, d, not figured in fig. 6c;
+Guinot & Richer de Forges 1997
+: figs 1a, c, 2c), but shorter and not dorsally visible in
+
+O. estuarius
+
+(
+Davie & Richer de Forges 1996
+: fig. 1a; not figured in fig. 1b). In contrast, there is only one, smaller knob in
+
+Richerius
+
+gen. nov.
+(
+Fig. 1B
+). The cheliped palm of
+
+R. marqueti
+
+gen. et sp. nov.
+is covered with long, flexible setae (
+Fig. 5
+C–D), instead of numerous spinules (or stiff setae) in
+
+O. pilosus
+
+(
+Fig. 6
+) (A. Milne-Edwards, 1873: pl. 18, fig. 6d;
+Ng & Richer de Forges 1996
+: fig. 6f), and sparse, short setae in
+
+O. estuarius
+
+(
+Fig. 8
+). In fact, the whole body (including the margins of the rostrum) and legs of
+
+O. pilosus
+
+are covered with spiniform, stiff setae that give a bristle appearance (
+Ng & Richer de Forges 1996
+: figs 5a–b, 6a, d;
+Guinot & Richer de Forges 1997
+: fig. 1a), whereas
+
+O. estuarius
+
+has a carapace with soft, short setae and legs with longer setae (
+Davie & Richer de Forges 1996
+: fig. 1a). The male cheliped fingers are practically joining in
+
+R. marqueti
+
+gen. et sp. nov.
+(
+Fig. 5C
+), but with a broad proximal gap in
+
+O. pilosus
+
+(
+Fig. 6
+A–B) (A. Milne-Edwards 1873: 322, pl. 18, fig. 6, 6d, as
+
+Elamene pilosa
+
+;
+Ng & Richer de Forges 1996
+: fig. 6f); in
+
+O. estuarius
+
+the chelae are narrower, with long fingers without marked gap (
+Fig. 8
+A–B) (
+Davie & Richer de Forges 1996
+: fig. 1). The grooves on the carapace dorsal surface are very distinct in
+
+O. pilosus
+
+, well marked in
+
+R. marqueti
+
+gen. et sp. nov.
+, whereas almost indiscernible in
+
+O. estuarius
+
+. The sterno-pleonal cavity is short in
+
+Richerius
+
+gen. nov.
+and in
+
+Odiomaris
+
+, and accordingly the pleon also. The male pleon is as a narrow triangle, with a long pleotelson in both
+
+Odiomaris
+
+species (A. Milne-Edwards 1873: pl. 18, fig. 6b, as
+
+Elamene pilosa
+
+;
+Ng & Richer de Forges 1996
+: fig. 7a–b;
+Guinot & Richer de Forges 1997
+: fig. 2a:
+
+O. pilosus
+
+;
+Davie & Richer de Forges 1996
+: fig. 2c:
+
+O. estuarius
+
+), markedly wider and with a much shorter pleotelson in
+
+R. marqueti
+
+gen. et sp. nov.
+(
+Fig. 2A
+). The intercalated platelets, which are completely demarcated and moveable in
+
+O. pilosus
+
+(
+Guinot 2011a
+: fig. 2), are only partially delineated in
+
+R. marqueti
+
+gen. et sp. nov.
+, and not detached in
+
+O. estuarius
+.
+
+The female pleon is rather similar in
+
+Richerius
+
+gen. nov.
+and
+
+Odiomaris
+
+, with five somites plus pleotelson. The G1 of
+
+Richerius
+
+gen. nov.
+(
+Fig. 2D
+) is curved at the base, otherwise with little curvature, with a terminal portion bearing fine setae and ending in one lobe without corneous process, whereas the G1 of
+
+Odiomaris
+
+is characterised by two distinct distal processes, a longer corneous process and a shorter lobular elongation of the stem (
+Fig. 7B
+:
+
+O. pilosus
+
+) (
+Ng & Richer de Forges 1996
+: fig. 7c– d:
+
+O. pilosus
+
+;
+Davie & Richer de Forges 1996
+: fig. 2c:
+
+O. estuarius
+
+).
+
+O. estuarius
+
+is a much smaller species than
+
+O. pilosus
+
+, and
+
+R. marqueti
+
+gen. et sp. nov.
+seems to be nearly as small as
+
+O. estuarius
+
+.
+
+
+The main differences to distinguish the two genera
+
+Odiomaris
+
+and
+
+Amarinus
+
+stated by
+Davie & Richer de Forges (1996: 259)
+were: 1) in
+
+Odiomaris
+
+, the G1 (see
+Fig. 7B
+) more slender, with two distinct distal processes, a longer corneous process and a shorter lobular elongation of the stem than in
+
+Amarinus
+
+; 2) in
+
+Odiomaris
+
+, the elongated triangular telson of the male pleon is significantly longer than wide at base, whereas in
+
+Amarinus
+
+the telson is more or less rounded and short, being much wider than long.
+
+
+The genus
+
+Amarinus
+Lucas, 1980
+
+(
+type
+species by original designation:
+
+Elamena lacustris
+Chilton, 1882
+
+) is known from more than ten species. They all inhabit low salinity environments, from brackish habitats to pure freshwater waters permanently (streams, lakes, swamps), and have a large distribution (
+New Zealand
+,
+Australia
+,
+Indonesia
+, the
+Philippines
+,
+Papua New Guinea
+). Cases where
+
+Amarinus
+
+has been reported from
+New Caledonia
+, as in
+Chuang & Ng (1994: 87
+, 90, table 1, under
+
+A. pilosus
+
+) and erroneously as in
+Guinot (2011a: 23)
+, are attributable to the fact that the species
+
+pilosus
+
+was previously associated with the genus
+
+Amarinus
+
+(see
+Lucas 1980
+) until
+Ng & Richer de Forges (1996)
+made it the
+type
+species of their new genus
+
+Odiomaris
+
+. So far, no species of
+Amarinu
+s has actually been reported in
+New Caledonia
+. Suspecting that our new species might belong to the genus
+
+Amarinus
+
+, we therefore carefully compared
+
+Richerius
+
+gen. nov.
+to
+
+Amarinus
+
+, and in particular to its
+type
+species,
+
+A. lacustris
+
+, another freshwater hymenosomatid.
+
+
+
+Richerius marqueti
+
+gen. et sp. nov.
+can be distinguished from
+
+Amarinus lacustris
+
+by: the wide male pleon, with prominent marks corresponding to intercalated platelets (
+Fig. 2A
+) (versus narrow and without intercalated platelets in
+
+A. lacustris
+
+, see Melrose 1975: fig.
+42g
+;
+Lucas 1980
+: fig. 7b); the G1 rather narrow and with one distal lobe without corneous process (
+Fig. 2D
+) (versus stout and without lobes, see Melrose 1975: fig. 42h–i;
+Lucas 1980
+: fig. 10e); and by the arrangement of antennules and antennae.
+
+
+In providing a key of the Southeast Asian hymenosomatids,
+Ng & Chuang (1996: 3–5
+, 6–12) have shown the presence of several groups of species within
+
+Amarinus
+
+, suggesting that the genus could be paraphyletic. Today, another problem arises, especially regarding the antennular morphology. Melrose (1975: 84, 87, figs 41–42, as
+
+Halicarcinus lacustris
+
+), who has thoroughly studied the
+type
+species
+
+A. lacustris
+
+, confined to lakes and non-tidal rivers of
+New Zealand
+and southeastern
+Australia
+, states that the antennules are “small, not visible dorsally when folded”. Her figure 41d actually seems to show a folded antennule, only with the broad basal article and the second cylindrical article, without the short, supposedly folded flagellum being seen [the frontal view of fig. 41e in Melrose (1975) shows a complete, unfolded antennule]. Our examination of
+
+Amarinus lacustris
+
+, on the other hand, reveals that both antennules and antennae are inserted very closely together at their bases and remain parallel, with both flagella visible dorsally, as represented by
+Lucas (1980
+: fig. 1d) for a generalised hymenosomatid or by Melrose (1975: fig. 43c) for
+
+Halicarinus tongi
+Melrose, 1975
+
+. In fact, if it is possible for the antennule of
+
+A. lacustris
+
+to fold itself down [but not obliquely along the rostrum as in
+
+Odiomaris
+
+(
+Fig. 7A
+), see A. Milne-Edwards 1873: pl. 18, fig. 6a], this does not correspond to the resting position. In the seven specimens of
+
+A. lacustris
+
+examined, the antennule and antenna are very closely inserted and remain parallel, both being stretched forward; the unfolded flagellum is visible dorsally in all individuals. In any event, the disposition of the antennule and antenna differs from that
+
+Odiomaris
+
+(
+Fig. 7A
+:
+
+O. pilosus
+
+) (
+Ng & Richer de Forges 1996
+: fig. 6c–d:
+
+O. pilosus
+
+).
+
+
+A picture of the cephalic region in ventral view of
+
+Amarinus angelicus
+
+(
+Holthuis 1968: 114
+, fig. 2b) shows an antennule “entirely hidden below the rostrum”, obliquely folded, which does not seem to correspond to the condition of
+
+A. lacustris
+
+. This character deserves to be reviewed for all species of
+
+Amarinus
+
+, and the allocation of
+
+Amarinus
+
+(including the
+type
+species and other included species) to the
+Odiomarinae
+needs further investigation. In the new species described here,
+
+Richerius marqueti
+
+gen. et sp. nov.
+(
+Fig. 1B
+), the antennule and antenna are separated at least at their insertion site, and only the antennal flagellum is visible dorsally; thus it shares an arrangement substantially similar to that of
+
+Odiomaris
+
+.
+
+
+It was the study of spermatozoa carried out first in the two species of
+
+Odiomaris
+
+,
+
+O. pilosus
+
+and
+
+O. estuarius
+
+, by
+
+Richer de Forges
+et al.
+(1997)
+
+and later in
+
+Elamena vesca
+
+by
+Jamieson & Tudge (2000)
+that showed the very particular nature of the hymenosomatid sperm within the
+Brachyura
+. Indeed, they are distinguished by at least nine major characteristics from those of all the other
+Brachyura
+taxa studied, particularly the groups with which they have been associated, the Majoidea Samouelle, 1819 and the Thoracotremata Guinot, 1977. The ‘hymenosomatid-type of spermatozoon’ is unique within
+Brachyura
+(
+
+Tudge
+et al.
+2014
+
+). The highly developed projection of the acrosome from the nucleus in hymenosomatid spermatozoon recalls the totally emergent acrosome of Podotremata Guinot, 1977 and may represent the plesiomorphic condition in the Eubrachyura Saint Laurent, 1980 (
+Guinot 2011a
+,
+2011b
+).
