Abstract A new species of the freshwater crab genus PotamonautesMacLeay, 1838 from Mporokoso, northern Zambia, southern Africa is described. Potamonautes caputanatisn. sp. is morphologically distinct from other species of this genus found in Zambia and its neighboring countries. The new species is recognised by a unique combination of morphological characters of the carapace, thoracic sternum, major cheliped, and adult male first gonopod. Illustrations of P. caputanatisn. sp. are provided and differences with congeners found elsewhere in Zambia and southern Africa are discussed. The addition of P. caputanatis n. sp. raises the number of species of freshwater crabs known to occur in Zambia to eleven. An updated checklist and key are provided to the Zambian species of freshwater crabs.

Seven species of freshwater crabs from three families are recorded from and around the Danum Valley Conservation Area in Sabah, Malaysian Borneo: Thelphusulacapillodigitus sp. n., Thelphusuladicerophilus Ng & Stuebing, 1990, Arachnothelphusaterrapes Ng, 1991, Terrathelphusasecula Ng & Tan, 2015, Parathelphusavalida Ng & Goh, 1987 (new record) (Gecarcinucidae); Isolapotamoningeri Ng & Tan, 1998 (Potamidae); and Geosesarmadanumense Ng, 2002 (Sesarmidae). The new species of Thelphusula Bott, 1979, can be distinguished from all congeners by a unique combination of morphological features, most notably the presence of dense patches of short setae on the fingers of the adult male chelipeds, as well as the structure of the male first gonopod. Arachnothelphusaterrapes is confirmed to be a phytotelm species. A key to all species in the conservation area is provided.

We report here on recent collections of freshwater crabs from Antsiranana Province, northern Madagascar. The specimens belong to three species, one of which is new to science and is described here. This raises the number of species of freshwater crabs found in Madagascar to 17. All are endemic to the island and all belong to the Afrotropical family Potamonautidae Bott, 1970. The new species, Foza manonae sp. nov., is compared to other species in this genus, and an updated key is provided. It is distinguished from the other three congeners by characters of the male first gonopod, sternum, carapace, and cheliped. The conservation status of the Malagasy freshwater crab fauna is summarized and discussed in light of the new material reported on here belonging to two other species, Madagapotamon humberti Bott, 1965 and Foza ambohitra Cumberlidge & Meyer, 2009.

Abstract New molecular and morphological analyses of the relationships of 77 specimens of potamonautid freshwater crabs collected from all parts of Madagascar support the monophyly of the island’s freshwater crab fauna and verify most of the existing taxa. The phylogenetic tree identified several new lineages that represent four new genera and 10 new species, and found Foza Reed & Cumberlidge, 2006 to be paraphyletic. The present work is the first of a series of articles reporting on these discoveries that provide an improved understanding of the relationships between the endemic potamonautid species found on this tropical island. We describe a new species of Malagasya Cumberlidge & Sternberg, 2002 from a phytotelmic habitat in northeast Madagascar, and establish Agoragen. nov. to accommodate Thelphusa goudoti H. Milne Edwards, 1853. Both of these new taxa are recognized based on combinations of morphological characters and molecular data. The new species of Malagasya is distinguished from the other two species of this genus, which are illustrated here for comparative purposes. Agora goudotin. comb. is endemic to Madagascar, and is compared with and distinguished from the eight other genera of freshwater crabs occurring in that country.

Rybocyclops Dussart, 1982 is a little-known stygobitic genus, hitherto represented by its type and only species, R. pauliani (Lindberg, 1954), from Madagascar. A second species, named Rybocyclops dussarti sp. nov., is described herein from an agricultural bore-well in southeastern India. The new species has a unique combination of morphological characters, which, inter alia, include: genital double-somite enlarged; anal operculum moderately large; furcal rami somewhat outcurved and about twice as long as wide; female antennules 11-segmented; legs 1–4 with spine formula 2.2.2.2, and setal formula 5.5.5.4; legs 1 and 4 without seta on inner margin of coxa and basis; leg 4 male with one seta more than in female on second endopodal segment; leg 5 fused to somite and represented by vague protuberance, bearing three setae; and leg 6 reduced to two setae. The generic diagnosis is partially amended for accommodating the new species. The discovery of R. dussarti sp. nov. is of much biogeographic interest because it is the first record of Rybocyclops from Asia and only the second freshwater stygobitic cyclopoid taxon from India, with apparent Gondwanan distribution.

A New Species

A taxonomic survey of Marphysa species (Polychaeta: Eunicida: Eunicidae) from coastal regions of northern Australia including recently collected specimens from a fish farm near Darwin, yielded three species: M. mullawa Hutchings & Karageorgopolous, 2003, a first record from northern Australia; M. mossambica (Peters, 1854; was Nauphanta mossambica), first confirmed record from Australia; and a new species, M. fauchaldi. The new species was recorded from intertidal muddy shores as well as in the sediments of fish farm ponds, where it was extremely abundant. It is characterised by a unique combination of chaetal features. A newly proposed informal subgroup of Marphysa, the Teretiuscula-group, is erected to contain the new species and other Marphysa species that share the possession of compound spinigerous chaetae in anterior parapodia only and the peculiar behaviour of encapsulating embryos in jelly cocoons. Morphologically, the new species falls between a group of Marphysa species having only compound spinigers and the recently resurrected genus Nauphanta, which completely lacks compound chaetae. The discovery of this new species necessitated a re-evaluation of the morphological features of Nauphanta and Marphysa species lacking falcigers, in particular homology of fan chaetae, the only apparent synapomorphy of Nauphanta. Fan chaetae appear to be a specialised type of pectinate chaetae, which are found also in species of Marphysa including the new species. Based on this finding, and an evaluation of other characters, Nauphanta is returned to synonymy with Marphysa. Further, an analysis of size-related variation of key morphological characters in M. mossambica and comparison with those in the types of M. novaehollandiae (Kinberg, 1865; formerly Nauphanta) and M. simplex Treadwell, 1922, indicated that both species should be synonymised with M. mossambica. A key is provided to identify Marphysa species of the Indo-west Pacific.

Abstract We describe a new species of gecko of the genus Pristurus from the Yemenite Red Sea Island Hanish al-Kabir. It is a small species (snout-vent length less than 30 mm) of the genus, distinguished from its congeners by a unique combination of morphological characters. Superficially, it is most similar to P. rupestris, but differs mainly by a longer and narrower snout, by its strongly compressed tail, presence of a lateral caudal groove, by a tail crest present in both sexes, by a higher number of scales bordering infralabials and a higher midbody scale count. The new species is tentatively considered to represent an island endemic. Its possible origin is briefly discussed.

A New Species

Phylogenetic reconstruction using the mitochondrial 16S marker shows that geographically separated populations of the poorly known Hyperolius cinereus (Anura: Hyperoliidae) from Angola form two distinct clades. The description of H. cinereus was originally based on only a single preserved adult male. Fresh material of both sexes allowed a detailed redescription of the species, which is restricted mainly to the south-draining Cunene and Cubango river systems. Bioacoustic and morphological characters, in conjunction with colouration differences, allow the description of a cryptic sister species from Lagoa Carumbo in north-eastern Angola, occurring in the Luele and Lovuo river systems of the Congo drainage basin. Tadpoles, for H. cinereus and the new species, are described.
