In the present study, an integrated taxonomic approach has been applied to clarify the taxonomic status, identity and distribution of bagridcatsh, Mystus tengara. Comparative morphometric evaluation of M. tengara identied in the present study from distant geographicallocation revealed variations of the traits in response to body length and environment, without signicant genetic distance. The observedmorphometric traits of M. tengara were found to be overlapping with available morphometric traits of M. tengara, M. carcio and M. vittatus.Maximum likelihood phylogenetic analysis based on mitochondrial cytochrome c oxidase (COI) gene also could not resolve their identity, andve paraphyletic clades comprising of M. tengara, M. vittatus and M. carcio from India, Nepal and Bangladeshwere observed. Morphologicaland genetic evidence along withcomparative evaluation of M. tengara, from its type locality, we consider M. tengara identied in the presentstudy to be true, with its distribution extending from North East India to West Bengal, North India, Central India, Northern peninsular India andBangladesh. The observation of paraphyletic subclade and evaluation of genetic distance between subclades reveals, there could be at leastfour cryptic species in this group. Further conrmation on the identity of M. vittatus and M. carcio, by integrated taxonomic approach basedon fresh specimens collected from type locality, is required. Not Available |
