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.

First record of Syncarida from Queensland,Australia, with description of two new species of Notobathynella Schminke, 1973 (Crustacea,Bathynellacea, Parabathynellidae)

Two new species of the parabathynellid genus Notobathynella Schminke, 1973 Schminke, HK. 1973. Evolution, System und Verbreitungsgeschichte der Familie Parabathynellidae (Bathynellacea, Malacostraca)Akad Wiss Lit Mainz, Math-Naturwiss Klasse, Mikrofauna Meeresbodens, 24: 1–192.  [Google Scholar] are described from Australia: N. octocamura sp. nov. and N. pentatrichion sp. nov. Notobathynella octocamura sp. nov. has eight claws on the distal endite of the maxillule, a character that is unique in the Parabathynellidae. It is also the first species of the genus with the following characters: five setae on the terminal segment of antenna, 26–28 teeth on labrum, 31 setae on maxilla, a three-segmented exopod on thoracopod I, five-segmented exopods on thoracopods IV and V, three setae and two claws on the fourth endopodal segment of thoracopods I to IV, and six setae on the uropodal exopod. This species also has a unique setal formula for some thoracopods. Notobathynella pentatrichion sp. nov. is unique in the genus with five setae on the uropodal exopod and, like N. octocamura sp. nov., has a one- or two-segmented exopod on thoracopod I, a four- or five-segmented exopod of thoracopod V, and three setae and two claws in the four segments of the endopod of thoracopods II to IV. The two new species extend the distribution of Bathynellacea in Australia and are the first species to be described from Queensland.

The different life stages for one of the described species were associated by DNA barcodes.     

Differentiation of external morphology of Oribatella Banks, 1895 (Acari: Oribatida: Oribatellidae), in light of the ontogeny of three species

Differentiation of external morphology of Oribatella Banks, 1895 was investigated, in light of the ontogeny of O. quadricornuta (Michael, 1880 Michael, AD. 1880. A further contribution to the knowledge of British Oribatidae. J Roy Micr Soc London, 3: 225–251. [Crossref] , [Google Scholar]), O. superbula (Berlese,1904 Berlese, A. 1904. Acari nuovi. Manipulus III. Redia, 2: 10–32.  [Google Scholar]) and O. calcarata (CL Koch, 1835 Koch, CL. 1835. “Deutschlands Crustaceen, Myriapoden und Arachniden”. In Regensburg, Germany: Verlag Friedrich Pustet 1–3.  [Google Scholar]) studied here for the first time, and that of the other species from the literature. The pattern of gastronotal setae in larvae is similar, except for lack of seta h ₃ in O. nortoni Behan-Pelletier, 2011 Behan-Pelletier, VM. 2011. Oribatella (Acari, Oribatida, Oribatellidae) of eastern North America. Zootaxa, 2973: 1–56. [Crossref] , [Google Scholar], while that of nymphs and adults is differentiated. The nymphs of most species have 15 pairs of gastronotal setae, but those of O. metzi Behan-Pelletier, 2011 Behan-Pelletier, VM. 2011. Oribatella (Acari, Oribatida, Oribatellidae) of eastern North America. Zootaxa, 2973: 1–56. [Crossref] , [Google Scholar] and most nymphs of O. calcarata have 13 pairs. The nymphs of most species carry the exuvial scalps of previous instars on apical parts of gastronotal setae da, while setae dm and dp, located under these scalps, are subjected to translocation, reduction in size or loss. In O. berlesei (Michael, 1898 Michael, AD. 1898. “Oribatidae”. In Das Tierreich, Lief. 3. Vol. 8 (Acarina). Berlin: Verlag von R. Friedländer und Sohn Edited by: Schulze, FE. 1–93. [Crossref] , [Google Scholar]), O. nortoni, O. quadricornuta and O. sexdentata Berlese, 1916 pair dp takes a more lateral position, compared with the larvae, in O. superbula and O. canadensis Behan-Pelletier and Eamer, 2010 Behan-Pelletier, VM and Eamer, B. 2010. The first sexually dimorphic species of Oribatella (Acari, Oribatida, Oribatellidae) and a review of sexual dimorphism in the Brachypylina. Zootaxa, 2332: 1–20. [Crossref] , [Google Scholar] it is reduced in size (in the latter species pair dm is also reduced), while O. metzi loses setae dm and dp. In contrast, the nymphs of O. calcarata do not carry the scalps, and usually lose setae c ₁ and dm. The adults of all species lose setae c ₁, c ₃ and d-series, compared with the tritonymph, and only 10 pairs of notogastral setae remain (c ₂, l-, h- and p-series), but O. quadricornuta and O. calcarata rarely retain seta c ₃ unilaterally, which indicates the order of setal loss in Oribatella according to Shaldybina (1972 Shaldybina, ES. 1972. Some morphological characters of ceratozetid moss mites (Oribatei). Ucenyje zapiski Gor Gosud Pedagog Institut, Gorki, 130: 35–66. In Russian [Google Scholar]).     

Revalidation of Hepsetus cuvieri (Castelnau, 1861) (Characiformes: Hepsetidae) from the Quanza,Zambezi and southern part of the Congo ichthyofaunal provinces

Hepsetus cuvieri (Castelnau, 1861 Castelnau, FL. 1861. Mémoire sur les poissons de l'Afrique australe, Paris: Mem Poiss Afr Australe. [Crossref] , [Google Scholar]), originally described from “lac N'gami” (Botswana) and synonymized with H. odoe (Bloch, 1794 Bloch, ME. 1794. Naturgeschichte der ausländischen Fische. Berlin., 8: 1–174.  [Google Scholar]) by Roberts (1984 Roberts, TR. 1984. “Hepsetidae”. In Check-list of the freshwater fishes of Africa (CLOFFA), Edited by: Daget, J, Gosse, JP and Thys van den Audenaerde, DFE. 138–139. Tervuren and Paris: ORSTOM. p.  [Google Scholar]), is revalidated. Hepsetus cuvieri can be readily distinguished from H. odoe based on a lower total number of gill rakers (8–13 versus 14–21); a generally higher number of scales between the dorsal fin and the lateral line (10½–11½ versus 7½–10½) and a higher number of scales between the adipose fin and the lateral line (6½–7½ versus 4½–6½) and other characters. A neotype is designated, as the holotype of this nominal species is apparently lost. Hepsetus cuvieri is restricted to the Quanza, Zambezi ichthyofaunal provinces and the southern part of the Congo Basin, i.e. the Congo ichthyofaunal province.
