Аннотация
Glyptothorax siangensis, new species, is described from the Siang River in Arunachal Pradesh, India. The new species can be distinguished from its congeners from the Ganga-Brahmaputra drainage and its neighbouring drainages by the following combination of characters: a thoracic adhesive apparatus with skin ridges present over almost the entire apparatus, including the sword-shaped median depression, which is narrowly opened posteriorly; an elongated dorsal spine distinctly greater than body depth at its origin, posteriorly serrated with 11–17 serrae; nuchal plate saddle-like with W-shaped extensions; shallow body depth; long nasal barbel, almost reaching the anterior margin of eye; a complete longitudinal black band across the distal half of dorsal-fin; and tips of neural spines extension visible as a row of ridges between dorsal-fin base and origin of procurrent rays of caudal-fin. This is the nineteenth species of Glyptothorax known from the Ganga-Brahmaputra drainage.
