Abstract

We describe Olyra praestigiosa, a new anguilliform bagrid catfish, from the Brahmaputra River drainage in Bangladesh and northeastern India. The new species differs from congeners in having the following unique combination of characters: interorbital distance 30-37% HL; body depth at anus 6-9% SL; length of adipose-fin base 99-16% SL; adipose fin separate from upper principal caudal-fin rays; post-adipose distance 15-18% SL; 17-22 anal-fin rays; caudal peduncle length 14-19% SL; and caudal peduncle depth 6-8% SL.
