Genetic differentiation and phylogenetic relationship of 11 Asian Sisorinae genera (Siluriformes: Sisoridae) with new record of .

Studies on systematics have been largely restricted to morphological data with few studies on examination of phylogenetic relations. However, no study has been done to evaluate genetic distance of the genera under sub-family and detailed phylogenetic relations within it. We used nuclear recombination activating 2 () gene and mitochondrial cytochrome c oxidase I () gene from 64 species to examine genetic differentiation and phylogenetic relationships within 11 Asian genera.
