+ + +Recent studies of the genus + +Chydorus + +( +Sinev 2014 +; + +Sousa +et al. +2024 + +) revealed that two species, South-East Asian + +C. breviceps +( +Stingelin, 1905 +) + +and African + +C. tilhoi +Rey & Saint-Jeans, 1969 + +have numerous differences from the majority of the genus in outer morphology, morphology of head pores, postabdomen and appendages, and probably should be placed into a separate genus.

Morphology of thoracic limbs of + +C. obscurirostris tasekberae + +(our data) and + +C. izvekovae +( + +Sinev +et al. +2022 + +) + +is generally similar to that of + +C. sphaericus + +group (see +Klimovsky & Kotov 2015 +; + +Sousa +et al. +2024 + +). While outer morphology of + +faviformis + +-group species is outstanding, the group shares main characters of + +Chydorus + +s. str. +in morphology of head pores, postabdomen, labrum and head appendages, and its position within the genus is wellsupported. + + + + +Distribution and ecology. + +Chydorus obscurirostris tasekberae +Frey, 1987 + +was described from Bera Lake in Peninsular +Malaysia +( +Frey 1987a +).

Known species of the group include Neotropical + +C. +( +C. +) +monacantha +(Sars, 1901) + +and + +C. +( +C. +) +undata +Sousa, Elmoor-Loureiro & Santos, 2015 + +, and African + +C. +( +C. +) +hardingi +(Brehm, 1957) + +. + +Coronatella +( +C. +) +acuticostata + +differs from both Neotropical species in a variable number of denticles on the posteroventral angle of valves – + +C. +( +C. +) +monacantha + +always has a single denticle, while + +C. +( +C. +) +undata + +always has two denticles spaced very close to each other (see + +Sousa +et al. +2015 + +). + +Coronatella +( +C. +) +hardingi + +(see +Van Damme 2016 +) has uniformly convex, not wavy posterior margin of valves, shorter basal spine of postabdomen, and 1 or 2 narrower denticles on posteroventral angle of valves (if there are two denticles, they are spaced very close to each other), and longer antennal spines, spine of basal segment of exopodite reach to the middle of apical segment, and apical spines 1.5 times longer, than apical segments. + + +Taxonomic notes. + +Coronatella +( +Coronatella +) +acuticostata + +was described from Sumatra ( +Sars 1903a +) as + +Alona acuticostata + +. Later, +Stingelin (1905) +described +Thailand +populations with three denticles on the posteroventral angle of valves as a special variety, + +Alona acuticostata +var. +tridentata + +. During the +XXth +century, this taxon was accepted as a synonym of + +Alona monacantha +Sars, 1901 + +( +Smirnov 1971 +; +Idris 1983 +; + +Maiphae +et al. +2008 + +). However, recent studies of the + +monacantha + +-group ( +Sinev 2004 +; + +Sousa +et al. +2015 + +; +Van Damme 2016 +) led to a re-evaluation of the status of Neotropical and African species of this group. Our data fully confirms the independent status of + +C. (C.) acuticostata + +, suggested during previous studies of Indo-Malaysian fauna ( +Sinev & Yusoff 2015 +; Sinev 2016). + + +Detailed morphological study of + +Coronatella +( +Coronatella +) +acuticostata + +is conducted for the first time. The species was described from Sumatra, so the studied populations are distributed quite close to the +type +locality. Our data confirm both an independent status of the species and its position within the + +monacantha + +-clade. The + +monacantha + +-group is distributed in Neotropical, Afrotropical and Indo-Malaysian Provinces. Recent revisions of the + +monacantha + +-group ( + +Sousa +et al. +2015 + +; +Van Damme 2016 +) and our data once again fully confirm the “Frey’s non-cosmopolitanism paradigm” ( +Frey 1982 +, +1987b +) for +Chydoridae +. Taxonomic status of the + +monacantha + +-clade populations recorded from +India +and +Sri Lanka +is unclear at the moment, but they probably belong to + +Coronatella +( +Coronatella +) +acuticostata + +as well. Interestingly, the most widely distributed tropical +Aloninae +clades are also present in +Australia +, but not the + +monacantha + +-group ( +Smirnov & Timms 1983 +). The only Australian species of +C +. ( + +Coronatella + +) is + +C. +( +C. +) +novaezealandiae +( +Sars, 1904 +) (Sinev 2022) + +. + + + + +Distribution and ecology. + +Coronatella acuticostata + +is a littoral species, associated with vegetation, distributed in Indo-Malaysian region. Our data suggests that all earlier records of + +Alona monacantha + +from South-East Asia (see Koronchinsky 2013) refer to +С +( +С. +) + +acuticostata + +. Taxonomic status of + +monacantha + +-group populations from +India +remains unclear, as the level of present descriptions is not sufficient to clarify the taxonomic status of local populations. + + + + \ No newline at end of file diff --git a/data/03/F2/AF/03F2AF08FFBEFFC9C7D2210DFE59FAA1.xml b/data/03/F2/AF/03F2AF08FFBEFFC9C7D2210DFE59FAA1.xml new file mode 100644 index 00000000000..7368dc5f200 --- /dev/null +++ b/data/03/F2/AF/03F2AF08FFBEFFC9C7D2210DFE59FAA1.xml @@ -0,0 +1,224 @@ + + + +New data on Cladocera (Crustacea: Branchiopoda) of Peninsular Malaysia + + + +Author + +Sinev, Artem Y. +Biological Faculty, M.

Color in ethanol pale yellowish. Body thin, cylindrical; significantly thicker at beginning of postbranchial region; gradually thinner towards posterior end. Prostomium subtriangular, slightly longer than wide, anterior end distinctly conical; eyespots present ( +Fig. 7A +). Nuchal organs elongated, located dorsally ( +Fig. 7A +). Two ciliated bands on the prostomium, dorsal one (ciliary slits) extended laterally, ventral one (crown like ciliary band) extended latero-dorsally without reaching the nuchal organs ( +Fig. 5A–B +). Peristomium fused with prostomium ventrally indistinct, starting point posterior to nuchal organs ( +Fig. 7A–B +), observed dorsally as a small fold overlapping posterior end of prostomium. Dorsal ciliary bands present on prebranchial segments, not seen posteriorly ( +Fig. 5A +). + + +Branchiae lanceolate, ciliated on the outer margin from the proximal part to near distal end on each branchia. Beginning from chaetiger 4, +holotype +with 9 pairs, +paratypes +9–10 pairs. Branchial length variable along the body; branchiae overlapping dorsally on chaetigers 6 to 10 ( +Figs 5A +, +6A +, +7A–B +), slightly longer than body width, then becoming progressively shorter. Last pair of branchiae cirriform in shape ( +Fig. 7B +). Notopodial postchaetal lobes shorter and subtriangular with wide base on prebranchial chaetigers ( +Figs 5A +, +7B–C +), globular to subtriangular on branchial segments ( +Figs 5A +, +6A–B +, +7D +), becoming subtriangular and thinner slightly longer on postbranchial, median and posterior segments ( +Figs 6C–D +, +7E–G +), last eight notopodial prechaetal lobes (preanal region) progressively longer and thinner ( +Fig. 6E +). Notopodial postchaetal lobe easily detached and lost in many median and posterior chaetigers. Lateral sense organs visible from chaetiger 2, seen on pre- and branchial chaetigers as depression on ventral side of notopodial postchaetal lobes ( +Fig. 6B +). Neuropodial postchaetal lobes as low ridges, indistinct from body wall. Notopodial chaetae numbering 4–10 long capillaries in a tuft, reduced in number and length posteriorly, and 1–2 lyrated notochaetae from chaetigers 2. Lyrate notochaetae with tines of different size and thickness along body, each with an inner row of 7–8 spines, shorter branch slightly thicker, appears rigid, ending in a more or less blunt tip, the longer branch has a very thin and flexible distal part, ending in a point ( +Fig. 5C +); long tine 2.4 times longer than short tine on anterior chaetigers, 2 times longer on median and posterior chaetigers; short tine 1.2 to1.4 times thicker than long tine. Lyrated notochaetae increase in size from anterior to posterior parapodia: 17.2µm from the base of the chaeta to the distal end of the short tine in branchial parapodia, 18.8 µm in middle parapodia and 20.2 µm in posterior parapodia ( +Fig. 7H–J +). Neuropodial chaetae long capillaries in two rows, four capillaries on first neuropodium, 12–14 capillaries anteriorly, reduced to 4–8 posteriorly. + + +Pygidium oval, pygidial region with nine cirri, one pair corresponding to notopodial postchaetal lobes of a normal sized segment, two pairs corresponding to two preanal segments, migrate to ventral side, and three elongated anal cirri, two dorso-lateral and one mid-ventral, mid-ventral cirrus slightly thicker and shorter than lateral ones ( +Fig. 6D–E +). + + + + +Etymology + +This species is named in honor of Andrew S.Y. Mackie, a great British polychaetologist who inspired the first author to study paraonid polychaetes. + + + +Remarks + + +The genus + +Paradoneis + +is composed of 30 valid species including two subspecies: + +P. lyra capensis +( +Day, 1955 +) + +and + +P. lyra guadalupensis +(Amoreux, 1985) + +. + + + +Paradoneis mackiei + + +sp. nov. + +, belongs to the group of + +Paradoneis +species + +with three pre-branchial chaetigers, lyrate notochaetae and without modified neurochaetae.
