On the systematics of genus Scylla De Haan,1833 of cochin backwaters, a South Indian estuary
Abstract
The present work is an attempt to describe the Scylla spp collected from Cochin backwaters, a South Indian estuary, for a period of two years from June 2010- May 2012. Identification and description of Scylla spp. was carried out based on the conventional taxonomic tools viz., morphological characters including the description of the first and second male gonopods and the third maxillipeds; morphometry as well as the molecular methods viz., sequencing of CO1 gene and the amplification of ITS-1 region. The present study confirms the occurrence of two species of Scylla, from Cochin backwaters, namely Scylla serrata and Scylla olivacea. The study also rules out the existence of Scylla tranquebarica in Cochin backwaters. The smaller species being identified as S. serrata is S. olivacea and the larger one being identified as S. tranquebarica is S. serrata.
