Lalramliana, S Lalronunga, Lalnuntluanga & HH Ng, 2015. Exostoma sawmteai, a new sisorid catfish from northeast India (Teleostei: Sisoridae). Ichthyological Exploration of Freshwater 26: 59–64.
Abstract
Exostoma sawmteai, new species, is described from the Barak River drainage in Mizoram State, northeastern India. It differs from congeners in having the posterior end of the adipose fin adnate with dorsal procurrent caudal-fin rays, a lunate caudal fin, total number of vertebrae, and morphometric features associated with the snout, eye, distance between the paired fins, body depth, adipose-fin base, and caudal peduncle. Evidence from the literature suggests that the genus is more diverse in the Indian subcontinent than currently recognized.
