Abstract

A single specimen of Parin’s spinyfin Diretmichthys parini was collected from the deeper water of west coast of India (Lat. 9°29.3’N; Long.75°45.9’E, depth 230 m). As wide variation in meristic counts of this species reported from other regions was observed, the present specimen is re-described by highlighting the characters overlooked in the original description. We also discuss the geographical variation among the con-specific of D. parini. An analysis of its osteology, otoliths, scale morphology and DNA barcode sequence confirmed the species identification. Molecular analysis of the present specimen using mitochondrial cytochrome oxidase subunit I (COI) gene sequences, confirmed the identity as D. parini with intra specific divergence of 0.47-3.2%.
