Two new species of the genus Chilibathynella Noodt, 1963 and Onychobathynella bifurcata gen. et sp. nov (Crustacea: Syncarida: Parabathynellidae) from New South Wales,Australia

Two new species of the parabathynellid genus Chilibathynella Noodt, 1963 Noodt, W. 1963. Estudios sobre Crustaceos de aguas subterraneas, III. Crustacea Syncarida de Chile Central. Investig Zool Chilenas, 10: 151–167.  [Google Scholar] are described from Australia. Chilibathynella joshuai sp. nov. has a unique combination of morphological characters, which includes five-segmented antenna, no epipodite on thoracopod I, two setae on the endopod of the male thoracopod VIII, homonomous row of 17 spines on uropodal sympod, uropodal exopod with four distal spines and a flat anal operculum. Chilibathynella digitus sp. nov. has two exclusive characters: six teeth on the pars incisiva of the mandible and a large, elongated digitiform protuberance (resembling a finger) on the basipod of male thoracopod VIII. The species also displays a unique combination of morphological characters, which includes five-segmented antenna, no epipodite on thoracopod I, no outer marginal seta on the first and second segments of the endopod of thoracopod I to VII, two setae on the endopod of the male thoracopod VIII, homonomous row of 12 spines on uropodal sympod, uropodal exopod with three distal spines and an unprotruded anal operculum. The two new species extend the distribution of the Chilibathynella genus in Australia from Victoria to New South Wales. A new genus and species of the family Parabathynellidae, Onychobathynella bifurcata gen. nov. sp. nov., is described from New South Wales, Australia. The new genus displays an evolutionary novelty, for Parabathynellidae and the entire group of Bathynellacea: the antennule, antenna, thoracopods, pleopod I and uropod have setae that are strong, thick, short, barbed and claw-like. This new genus is the first in the family without smooth setae on the antennule and antenna. The new genus also has a combination of characters that makes it unique in Parabathynellidae: the antennule is eight-segmented like Octobathynella Camacho and Hancock, 2010 Camacho, AI and Hancock, P. 2010. A new record of Parabathynellidae (Crustacea, Bathynellacea) in Australia: a new genus and species from New South Wales. J Nat Hist, 44(17–18): 1081–1094. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]; the antenna is five-segmented; the labrum has 20 teeth; the exopod of thoracopod I to VII has only one segment; the endopod lacks dorsal setae on the first segment and the epipod is absent from thoracopod I; first pleopods are present and resemble two barbed curved claws; there are 18 bifid spines on the sympod, two spines and four setae resembling strong barbed claws on the endopod and six robust setae on the exopod of the uropod.     

New records of Bathynellacea (Syncarida,Bathynellidae) in North America: three new species of the genus Pacificabathynella from Montana,USA

Three new species of the genus Pacificabathynella Schminke and Noodt, 1988 Schminke, H K and Noodt, W. 1988. Groundwater Crustacea of the order Bathynellacea (Malacostraca) from North America. J Crustacean Biol., 8(2): 290–299.  [Google Scholar] are described from groundwater aquifers in glaciated North America (Montana, USA). This is the first time that this genus, known previously only from the state of California, has been documented in Montana. Pacificabathynella and Paradoxibathynella Serban, 2000 Serban, E. 2000. Uenobathynella n.g., Parauenobathynella n.g., Morimotobathynella n.g., Nihobathynella n.g. et Paradoxibathynella n.g., Bathynellinae du Japón (Bathynellidae, Bathynellacea, Podophallocarida). Travaux Inst Spéol “Émile Racovitza”, 36: 3–61.  [Google Scholar] are the only genera that show sexual dimorphism in thoracopod VI. Pacificabathynella kalispellensis sp. nov. has several unique features: the setal formula of the antenna (0/2+exop/3/12/6/8/5); the setal formula of the maxilla (7/4/7/6); the presence of an epipod on thoracopod II; tufts of setulae and abundant setae on the basipod and endopod of thoracopods I to V; the epipod of thoracopod VIII female three times longer than the basipod; three smooth setae on the exopod of the female thoracopod VIII; eight spines on the endopod of the uropod and the endopod longer than the sympod, whereas the opposite is typical. Pacificabathynella stanfordi sp. nov. has several unique features: only five setae on the exopod of thoracopods II to VII, while six setae are common in the genus; only six setae on the second segment of the first pleopod; five spines on the endopod and seven setae on the exopod of the uropod. Pacificabathynella ruthae sp. nov. is the largest species and has several unique features: antennule equal in size to the antenna, whereas in the rest of the species of the genus the antenna is larger; the projection of the inner lobe of the male thoracopod VIII is bidentate and there are six spines on the endopod and nine setae on the exopod of the uropod. The three new species have slight differences in the pars molaris of the mandible and in thoracopod VIII of males, and there are other minor differences between the females and the species Pacificabathynella sequoiae. The new taxa, together with the new genus Montanabathynella described separately, represent a 30% increase in North American taxa. Considering the glaciated landscape and the fragmented nature of alluvial aquifer habitat, we believe that there is a profound lack of critical knowledge of the biogeography and biodiversity of syncarids in North America.     

The first record of Syncarida in Montana,USA: a new genus and species of Parabathynellidae (Crustacea,Bathynellacea) in North America

Montanabathynella salish gen. nov. sp. nov., of the family Parabathynellidae, from Montana, USA, is described. The new species displays several exclusive characters: distal endite of the maxillule with nine claws and a very large and distinctive male thoracopod 8 with four lobes in the basal penial region and a long recurved exopod without setation. It also presents a unique combination of characters: antennule seven‐segmented; antenna six‐segmented; labrum with 18 teeth; exopod of thoracopods three‐ to six‐segmented, endopod with one dorsal seta on the first and second segments and epipod only present on thoracopods 4 to 7; pleopods absent; endopod of thoracopod 8 male with two setae and exopod without setae; female thoracopod 8 having two segments, first segment with two groups of denticles and the second one with three long barbed setae; 15 spines on sympod, four spines and spinous process on endopod and 12 setae on exopod of uropod.     

Disentangling an Asian puzzle: Two new bathynellid (Crustacea,Syncarida, Parabathynellidae) genera from Vietnam

In this paper the 17 asiatic species of the family Parabathynellidae are reviewed from a taxonomic point of view using bibliographic data. Two new genera and two new species are described from caves in Vietnam. Paraeobathynella n. g. presents a unique combination of characters (antennule: seven segments; antenna: six segments; mandible: pars incisiva with five teeth and pars molaris with 10 teeth; maxillule: distal endite with seven claws; exopod of the thoracopods with three or more segments and epipods present in thoracopods 3–7; pleopods absent; endopod of the Th 8 male with two setae; seven spines on the sympod and two spines on the endopod of the uropod and the small minimum size of the adult body) and exclusive characters like the Th 8 female having two small spines and one long seta and the general size and aspect of the Th 8 male and its lobes. Sketinella n. g. presents a unique combination of characters (antennule: eight segments; antenna; six segments; mandible: pars incisiva with six teeth and pars molaris with eight teeth: maxillule: distal endite with seven claws; exopod of the thoracopods with three or more segments and epipods present in Th 3–7; endopod of the thoracopod 8 male with two setae; 12 spines on the sympod and two spines on the endopod and seven setae on the exopod of the uropod) and characters exclusive to the asiatic species are: a pair of pleopods reduced to a single seta; a very distinctive basipod and outer lobe of the Th 8 male and an exopod of the Th 8 male with a small tooth or protuberance. This is the first time that the Parabathynellidae has been found in Vietnam, this find extends the range of distribution of this family in Asia.     

A new genus of Parabathynellidae (Crustacea: Bathynellacea) in New South Wales,Australia

A new genus and species of the family Parabathynellidae, Octobathynella peelensis gen. nov. sp. nov., is described from New South Wales, Australia. The new genus displays several exclusive characters: a very large and distinctive male thoracopod VIII with one crest-like projection containing two lobules on the basipod; and four aesthetascs on segments six and seven of the antennule. It also has several combinations of characters that make it unique in the Parabathynellidae, specifically that: the antennule is eight-segmented (a new character in the Australian species); there are seven segments in the antenna; the labrum has 18–20 teeth; the exopod of thoracopod I has three to four segments and the exopod of thoracopod II has four segments; the endopod has one dorsal seta on the first and second segments and the epipod is absent on thoracopod I; pleopods are absent; the endopod of the male thoracopod VIII has two setae and the exopod has setules; there are 10–12 spines on the sympod, three or four spines on the endopod and five setae on the exopod of the uropod. The new genus and species is placed into context with all known Bathynellacea in Australia, and the biogeographic patterns are discussed for this ancient group of subterranean crustaceans.     

Ten new species of the genus Brevisomabathynella Cho,Park and Ranga Reddy, 2006 (Malacostraca,Bathynellacea, Parabathynellidae) from Western Australia

Ten new species of Brevisomabathynella Cho, Park and Ranga Reddy, 2006 Cho, JL, Park, JG and Ranga Reddy, Y. 2006. Brevisomabathynella gen. nov. with two new species from Western Australia (Bathynellacea, Syncarida): the first definitive evidence of predation in Parabathynellidae. Zootaxa., 1247: 25–42.  [Google Scholar] are described and illustrated from the arid region of Western Australia. Comparison of the external morphology revealed the presence of three common characters distributed among the 10 species: the five-segmented antenna, the absence of the basipodal seta on the male thoracopod VIII and the absence of a basiventral seta on the uropodal exopod. This character combination is not found in Notobathynella and Billibathynella, but only in Brevisomabathynella, a genus known from two described species both with unusual characters. Despite the three common attributes, the 10 new species differ remarkably from these two described species, but could not be defined by their own synapomorphy. Consequently, and cognizant of a previously performed molecular analysis, we assign the 10 new species to Brevisomabathynella and amend the generic diagnosis. The species inhabit shallow aquifers in groundwater calcretes and each appears to be endemic to a given calcrete formation. The two species previously known and the 10 species now described include four sympatric species pairs, with similar-sized sympatric species differing markedly in body form. Brevisomabathynella inhabit groundwater up to at least marine salinity.     

Redefinition of Nipponbathynella based on the four new species from East Asia (Crustacea: Bathynellacea: Parabathynellidae)

Four new species of the parabathynellid genus Nipponbathynella Schminke, 1973 are described from South Korea (Nipponbathynella leesookyungae sp. nov., Nipponbathynella donggangensis sp. nov. and Nipponbathynella wanjuensis sp. nov.) and Japan (Nipponbathynella shigaensis sp. nov.), raising the number of known species to seven. Nipponbathynella leesookyungae is characterized by the convex ventral surface of the labrum and the rich ornamentation (with three spinules and two teeth) of the exopod of male thoracopod VIII; N. donggangensis by the distal spine on the distal maxillular segment with many dentils; N. wanjuensis by the endopod of the male thoracopod VIII with one seta (instead of two) and the serrated endopodal spur of the uropod; and N. shigaensis by the basipod of thoracopods II–VII carrying strong hairs on their outer margin. The three new and one known (Nipponbathynella pectina) South Korean species share a bur-like inner lobe of the male thoracopod VIII, suggesting their close relationship. Based on the one-segmented exopod on thoracopod I and two-segmented exopod on the thoracopods II–VII, the bell-shaped male thoracopod VIII and the uropod with sympod carrying a large distal spine in addition to several proximal spines of smaller size, with endopod drawn into a spur and with exopod carrying a seta, a close phylogenetic relationship between Nipponbathynella and Arisubathynella Park and Eun, 2012 is proposed.

The first record of Bathynellacea from Thailand: a new genus and species of Parabathynellidae (Crustacea: Syncarida)

A new genus and species of the family Parabathynellidae, Siambathynella laorsriae gen. nov. et sp. nov. is described from Thailand. The new genus displays an exclusive character: a distinctive male thoracopod VIII with a row of denticles on the basipod. The new species also displays a unique combination of morphological characters, including a seven-segmented antennule, seven-segmented antenna, sexual dimorphism on the antennule, exopod of thoracopod I one-segmented, exopod of thoracopod II–VII two-segmented, male thoracopod VIII lacking basipodal seta, female thoracopod VIII with two setae, lacking pleopods, sympod of the uropod with inhomonomous row of spines, and endopod of uropod with a spinous distal process and a large distal spine ornamented with rows of setules. This is the first record of Bathynellacea (family Parabathynellidae) in Thailand, extending the distributional range of this taxon in Asia.

Two new species of the family Photidae (Amphipoda: Corophiidea: Photoidea) from Brazilian waters,with description of Rocasphotis gen. nov.

A new species, Photis sarae sp. nov., is herein described from Guanabara Bay, Rio de Janeiro. The new species is similar to the Hawaiian species, Photis hawaiensis Barnard, 1955, and an undescribed species, Photis sp. F (LeCroy 2000 LeCroy, S.E. An illustrated identification guide to the nearshore marine and estuarine Gammaridean Amphipoda of Florida. Volume 1. Families Gammaridae, Hadziidae, Isaeidae, Melitidae and Oedicerotidae. Florida Department of Environmental Protection, Tallahassee, Annual Report, Contract No. WM724, 195. 2000.  [Google Scholar]), from Biscayne Bay, Florida. Photis sarae sp. nov. can be distinguished from both species in having gnathopod 2 basis with two long setae on posterior margin, palm with only one spine (excluding palmar corner), pereopod 3 anterior margin of merus with long plumose and simple setae, and dactyli of pereopods 5–7 with accessory spine and telson trapezoidal with distal margin concave. Also, Rocasphotis gen. nov. is described based on material collected from Atol das Rocas, which is closely related to the genus Photis and also corresponds to a new species. Rocasphotis gen. nov. mainly differs from Photis in having antenna 1 shorter than antenna 2, peduncular article 1 longer than article 3, accessory flagellum absent, coxae 1–4 with sparse slender setae; lateral cephalic lobe weakly extended and acute distally; eyes large, poorly developed, composed of sparse ommatidia, and partly enclosed in the lobe. A key for all genera of the family Photidae is given.     

Four species of Caligus Müller, 1785 (Copepoda,Siphonostomatoida, Caligidae) parasitic on marine fishes of Taiwan

Four species of Caligus, with two new species, are reported from five species of marine fishes of Taiwan. They are: Caligus arii Bassett‐Smith, 1898 Bassett‐Smith, P. W. 1898. Further new parasitic copepods found on fish in the Indo‐tropical region.. Annals and Magazine of Natural History (Series 7), 2: 77–98. [Taylor & Francis Online] , [Google Scholar] on the body surface of Trichiurus lepturus Linnaeus, Caligus dasyaticus Rangnekar, 1957 Rangnekar, M. P. 1957. Caligus dasyaticus sp. nov. and Caligus dussumieri sp. nov., (Copepoda) parasitic on Bombay fishes.. Journal of the University of Bombay, 25: 16–22.  [Google Scholar] on the body surface of Dasyatis navarrae (Steindachner), Caligus dactylus n. sp. on the gill filaments of Dactyloptera peterseni (Nyström), and Caligus lutjani n. sp. in the oral/gill cavities of Lutjanus argentimaculaltus (Forsskål) and Lutjanus bohar (Forsskål). Both C. arii and C. dasyaticus are reported for the first time from Taiwan. Caligus dactylus differs from its congeners by the possession of the following combination of features: large myxal process on the maxilliped; a pair of parallel tines on the sternal furca with truncate tip; simple elements (without accessory process) at the tip of leg 1 exopod; and an armature formula of I‐0; I,III on leg 4. Caligus lutjani is distinguished by carrying a two‐segmented abdomen; a pair of diverged tines on the sternal furca with acute tip; an accessory process on the middle two of the terminal four elements on the exopod of leg 1; and a bipectinate, spiniform process on the exopod of leg 4 at the insertion of each of the five outer spines.
