Keywords:
Macrognathus siangensis sp.nov, Siang river, Mastacembelid diversity, Northeast India
Abstract
Macrognathus siangensis, new species, from the Siang River, Brahmaputra drainage, northeast India, is distinguished from all other congeners by the following combination of characters: lack of rostral tooth plates, dorsal-fin spines 15-19, dark spots like imperfect ocelli along the base of dorsal soft branched fin rays 7-11, dark blotches at the mid-lateral sides of body 22-27, dorsal fin rays with two rows of parallel greyish streaks, caudal fin rays with 4-6 striated greyish streaks and body width 59.0-67.4% of its depth. A key to Macrognathus species of northeast India including the newly described one is provided.
