|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 Latin bis meaning two, and macula, meaning spot; in reference to the presence of two dark spots in this species.|

|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.
The two spots are found above and behind the pectoral-fin base and the other at the base of the caudal peduncle. The fish often idebntified as O. bimaculatus (and most commonly encountered in the aquarium trade) is a Southeast Asian species, Ompok siluroides which has a rounder head and a mottled brown colouration, while O. bimaculatus are silvery and have a sharper head.
|Sexing||Males are more slender and have strong serrations on the posterior edge of the pectoral spine (females lack these serrations).|
