Identification Catfishes of the genus Pterocryptis Peters, 1861, are medium sized members of the Siluridae usually found in fast flowing mountain streams throughout India, southern China and Southeast Asia. Pterocryptis had been considered a junior synonym of Silurus Linnaeus, 1758, until its rediagnosis by Bornbusch (1991). There are 16 nominal species of Pterocryptis (Ng & Freyhof, 2001). They can be distinguished from other siluroids by having a small dorsal fin,upper jaw longer than lower jaw and a confluent anal and caudal fin with a distnct notch between them.

Easily distinguished by its blunt head and truncate caudal fin.
There are actually several species of Pterocryptis currently identified as . The true P. cochinchinensis is restricted to central Vietnam.
Sexing Males have a small conical genital paiplla while females have a large, flattened, leaf-like papilla.
Males also have strong serrations on the posterior edge of the pectoral spine that females lack.
