Amblyceps cerinum, a new catfish (Teleostei: Amblycipitidae) from northeastern India

Abstract

Amblyceps cerinum, a new South Asian amblycipitid catfish species, is described from the Brahmaputra River drainage in northern West Bengal, India. The new species can be distinguished from congeners in having a combination of upper jaw longer than lower, incomplete lateral line terminating beneath posterior insertion of dorsal fin, length of adipose-fin base 32.4-38.3% SL, caudal peduncle length 21.9-24.5% SL, caudal peduncle depth 9.2-11.2% SL, 41-44 post-Weberian vertebrae, posterior end of adipose fin separated from dorsal procurrent caudal-fin rays by distinct notch, and truncate caudal fin. The taxonomic status of A. tenuispinis is also discussed and a neotype designated for this species. © 2010 Magnolia Press.
