|Scientific Name||Ompok karunkodu Ng, 2013|
|Type Locality||India: Tamil Nadu, Amaravathi River in the vicinity of Amaravathi Dam, 10°24'N 77°16'E.|
|Pronunciation||Awm pok - ka ron ko du|
|Etymology||The etymology of Ompok is unclear. It is believed to be a corruption of the Indonesian name for mid-sized silurid catfishes, limpok. The specific epithet comes from the Tamil karun, a contraction of karuppu, meaning black and kodu, meaning line. This refers to the dark midlateral stripe running along the side of the body in this species. Used as a noun in apposition.|
|Identification||The catfish genus Ompok La Cepède, 1803, consists of medium-sized silurid fishes found in inland waters throughout South and Southeast Asia. The genus is traditionally diagnosed by the presence of a short dorsal fin with 4 rays, strongly forked caudal fin, subcutaneous eye that is set immediately posterior to the mouth rictus and two patches of palatal teeth (Weber & de Beaufort, 1913). Bornbusch (1995) showed that Ompok, as currently understood, is probably paraphyletic.
Ompok karunkodu can be distinguished from all congeners in the Indian subcontinent in having a markedly convex predorsal profile (vs. with a slight or distinct concavity in the supraethmoidal or supraoccipital region), and a unique combination of the following characters: prognathous lower jaw causing anterior profile of head to appear rounded when viewed laterally, maxillary barbel reaching to base of pectoral-fin spine,eye diameter 13.7% HL, head width 13.0% SL, body depth at anus 14.2% SL, 65 anal-fin rays, caudal peduncle depth 5.0% SL, caudal-fin length 12.6% SL, caudal fin with rounded lobes, 54 vertebrae, and dark midlateral stripe running along sides of body.
|Sexing||Males have strong serrations on the posterior edge of the pectoral spine (females lack these serrations.|
|Distribution||Known from the Amaravathi River (a right-hand tributary of the Kaveri River) in southern India.
