Épines dorsales (Total) : 2; Rayons mous dorsaux (Total) : 6; Épines anales: 3 - 4; Rayons mous anaux: 10; Vertèbres: 36 - 37. This species Is distinguished from its congeners from the Ganga–Brahmaputra drainage and its neighbouring drainages by the following set of characters: a thoracic adhesive apparatus with skin ridges in almost over the entire apparatus, including the depressed region with a sword-shaped median depression, which is narrowly opened posteriorly, not extending anteriorly onto the gular region; dorsal spine is distinctly greater than body depth at its origin, posteriorly serrated with 11-17 serrae, its length 18.0-19.0% SL; nuchal plate is saddle-like with W-shaped extensions; shallow body depth with depth at anus 13.3-14.9% SL; caudal peduncle depth, 8.3-9.1% SL; long nasal barbel, 27-35% head length; ventral surface of pectoral spine and first pelvic-fin ray non-plaited. Colouration: a complete longitudinal black band across the distal half of dorsal-fin; and 4-6 tips of neural spines extension visible as a row of edges between adipose fin and origin of procurrent rays of caudal-fin (Ref. 130789).
Cross section: compressed.
