A new record of Scylla olivacea (Dcapoda, Bachyura, Prtunidae) from Goa, central west coast of India – A comparative diagnosis

Abstract

Taxonomic studies on mud crabs (Scylla) reveal considerable ambiguity in species identification owing to overlap of morphological characters. Present study consists a new record of Scylla olivacea along with a comparative diagnosis with S. serrata from the region. Further, minor phenotypic variations in the present S. olivacea specimens could be attributed to geographical isolation from existing populations.
