|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.
Pterocryptis anomala can be distinguished from congeners by the unique combination of the following characters: length of dorsal fin 7.9–10.1% SL, depth of caudal peduncle 7.2–9.7% SL, head length 16.6–20.7% SL, eye diameter 9.2–13.7% SL, dorsal-fin rays 3–4, anal-fin rays 59–69, principal caudal rays 14–16, small conical genital papilla in both sexes, anal and caudal fins separated by a deep notch, narrow cheeks, circular eye and weakly contrasting mottled coloration.
|Sexing||Spine in males with broad and somewhat flattened dorsoventrally, with 5–9 serrations on posterior edge, increasing in size distally; proximal articulated segments with 0–6 serrations on posterior edge. Spine in females or juveniles slender, with 0–7 small serrations on posterior edge, and 0–3 serrations on posterior edges of proximal articulated segments.|
