New records of Epixanthus frontalis and Heteropanope glabra (Decapoda: Brachyura: Oziidae, Pilumnidae) for Goa, India, with identification keys of their respective genera

Abstract

Two rock crabs, Epixanthus frontalis and Heteropanope glabra, are reported for the first time from Goa, west coast of India. Detailed scanning electron microscopy (SEM) photographs of the male first gonopods of both these species are provided for the first time. Identification of these species using available published literature is difficult. Hence, identification keys to all the species of the two genera, Epixanthus and Heteropanope, based on extensive comparisons of their respective congeneric species, are prepared for the first time.
