Re description and molecular identification of (Stimpson 1858) (Decapoda: Brachyura: Portunidae) based on fresh material from the coastal waters, Pakistan.

(Stimpson1858), re-described as a new report, based on an integrative taxonomy approach combining 16S rRNA partial sequence of mitochondrial DNA and morphological analyses was used for the accurate identification of specimens. The morphological and molecular analysis provides the confirm evidence of in coastal waters of Pakistan. Results were confirmed by amplification of partial sequences of 16S rRNA mt-DNA gene and the sequence was searched for similarity using BLASTn (Basic Local Alignment Tool), the result showed 97% sequence similarity with partial sequences of Stimpson, 1858 as obtained from gene bank. The attained sequence was submitted to gene bank after confirmation of genetic and morphological similarity. High sequence similarity with accession no: FJ152165.1 indicated, that misidentification of species does not occur.
