Currothelphusa asserpes gen. nov., sp. nov. (Crustacea Decapoda Brachyura Sundathelphusidae) from a cave in Halmahera, Moluccas

Abstract

A new genus and species of freshwater crab of the family Sundathelphusidae, Currothelphusa asserpes gen. et sp. nov., is described from a cave on the island of Halmahera in the Indonesian Moluccas. It is allied to the genera Sundathelphusa and Archipelothelphusa, but easily separated by its more convex carapace, long ambulatory legs, well developed epigastric and postorbital cristae, and distinctly T-shaped male abdominal segment. The holotype has two pairs of male second pleopods, which is an anomalous condition.
