Abstract
Members of the genus Barilius are known for their economic values. However, due to human activities and natural calamities, Barilius bendelisis faces massive population loss, especially in eastern India. We applied both morphology and molecular approaches to identify Barilius bendelisis from transboundary river Torsa, Raidak-1 and Mansai (Jaldhaka), West Bengal, India. Further, we compared genetic divergence of Barilius bendelisis from other members of the genus Barilius available in India. The Bayesian (BA) phylogeny clearly distinguishes all the studied species with reciprocal monophyletic criteria and represents multiple clades within Barilius bendelisis, indicating cryptic diversity and probable occurrence of allopatric speciation within India.
