Identification Sisorid catfishes of the genus Glyptothorax Blyth are benthic inhabitants of torrential waters of rivers and streams in montane and submontane parts of tropical Asia. The members of the genus are adapted to attach themselves to rocks and boulders against strong currents by means of a thoracic adhesive apparatus comprising grooves and folded pleats of skin parallel or oblique to the longitudinal axis of the body. The genus has a wide distribution, ranging from Turkey and Syria in the west, to India and China in the east, and extending further southeastward to Indonesia. With 84 nominal species, Glyptothorax are the most speciose genus of catfishes in Asia (Eschmeyer et al., 1998, Ng, 2005); 67 species were treated as valid by Thomson & Page (2006).

Distinguishable by its two dark saddles on the body (at dorsal fin origin and under the adipose fin), becoming indistinct in specimens >10 cm SL. The rest of the body is usually covered by irregular spots and blotches. The neural spines are distally pointed and there is an absence of a ridge or series of bumps along the dorsal mid-line between the dorsal and adipose fins.
