Abstract

A new species of mangrove sesarmid crab, Nanosesarma gomantaka n. sp. is described on the basis of specimens collected from Chapora Estuary in Goa State, India. Nanosesarma gomantaka n. sp. closely resembles N. pontianacense (De Man, 1895) from Southeast and East Asia in having an elongated carapace, arcuate frontal lobes with a median notch and the presence of strong proximal spine on outer surface of male cheliped dactylus, but can be distinguished by the generally more arcuate frontal lobes with deep V-shaped median notch, the tip of the external orbital angle not extending beyond the rudimentary epibranchial tooth, and the proportionately more slender male first gonopod, with a straight distal portion bent at an obtuse angle.
