Abstract
Abstract A new species of gecarcinucid crab, Barytelphusa choprai sp. nov., is described here from the Eastern Ghats in Andhra Pradesh state of India. The new species differs from all three congeners by its convex and trapezoidal carapace, pale white colouration, and by a distinct structure of the male gonopod G1. It differs from its congeners by genetic distance (p-distance) in the range of 5.7-13.6% in partial mtCOI gene sequence. The habitat at the type locality is a slow flowing shallow stream with rocky substratum, covered with silt and debris, and devoid of aquatic vegetation.
