A new species of freshwater crab of the genus Hydrothelphusa A Milne-Edwards, 1872, is described based on specimens collected from a forested region of southeastern Madagascar. Hydrothelphusa vencesi n. sp. is clearly distinguished from its congeners by its distinctive first gonopod (G1) with a terminal article that is in the form of a long straight-sided cone, and by a dorsal membrane at the segment junction of G1 that is broad and diamond-shaped. A key is provided to separate the five species of Hydrothelphusa.

Abstract A new species of freshwater crab of the genus Teretamon Yeo & Ng, 2007, Teretamon husicum sp. nov., is described here from Husa Town, Longchuan County, Dehong Prefecture, Yunnan Province, China. Teretamon husicum sp. nov. can be distinguished from other species by a suite of morphological characters, including a bilobed frontal margin, smooth posterolateral regions, and a broadly rounded dorsal flap on the G1 terminal segment. An updated identification key for the species of the genus Teretamon is provided.

A New Species

A new species of pseudothelphusid crab, Allacanthos yawi n. sp., from the Río Volcán drainage, Puntarenas Province, southern Costa Rica, Central America, is described and illustrated. This is the second species to be assigned to the genus Allacanthos Smalley, 1964. The new species is distinguished by its congener by having a first gonopod with a mesiolaterally flattened distal portion, a concave and nearly smooth subdistal portion of the lateral and cephalic sides, a narrow marginal process with a nearly straight distal border, and a lateral lobe with a sharp tip on the apex. An amended diagnosis for Allacanthos is provided.

A New Species

Abstract The identity of the potamid freshwater crab, Indochinamon manipurense (Alcock, 1909) from the state of Manipur in northeast India, is clarified based on an examination of the type specimens. The species is redescribed and a lectotype designated. Specimens from the same region previously referred to this species were compared to the types of I. manipurense and shown to belong to a new species of Potamiscus Alcock, 1909, instead. The new species, Potamiscus takedai sp. nov., can easily be separated from I. manipurense by the characters in the carapace, third maxilliped, male pleon, male gonopods, and female vulvae. Potamiscus takedai sp. nov. can be differentiated from congeners mainly by the strongly bent terminal segment of the male first gonopod and a relatively shorter distal segment of the male second gonopod.

A New Species

A new species of hymenosomatid freshwater crab, Neorhynchoplax Sakai, 1938, is described from Patna, Bihar, northern India. The species resembles the Indian N. woodmasoni (Alcock, 1895) and N. alcocki Kemp, 1917, but differs in the form of the carapace, armature on the cheliped merus, number of spines on the dactylus of the ambulatory legs, and structure of the male abdomen.
