Diagnosis

It is distinguished from other species of Glyptothorax from rivers draining the Ganges Delta in having a combination of the following characters: nasal barbel not reaching anterior orbita margin; interorbital distance 27.0-31.4% HL; head length 23.7-25.3% SL; head depth 12.5-14.2 % SL; thoracic adhesive apparatus with narrow elliptic central depression that is almost wholly enclosed posteriorly by skin ridges (striae) and with single, non-diverging series of striae running along its edges; width of adhesive apparatus 55.8-72.1% its length; unculiferous ridges of adhesive apparatus not extending anteriorly onto gular region; absence of striae on first pectoral- and pelvic-fin elements; pectoral-fin length 20.7-24.9% SL; smooth posterior

edge of dorsal spine; dorsal-to-adipose distance 17.8-23.6% SL; body depth at anus 11.3-13.8% SL; pelvic-fin length 15.9-19.1% SL; length of anal-fin base 13.9-16.2% SL; caudal peduncle length 21.4-23.9% SL; and caudal peduncle depth 6.4-7.6% SL (3.1-3.4 times in its length). In addition to these characters, it differs from congeners in the Kaladan River drainage in eastern Mizoram by its dorsal-spine length 13.0-17.1% SL (Ref. 91243).
