β¦ Synopsis
The identities of the nominal species in the Ompok hypophthalmus group of silurid catfishes, namely Ompok hypophthalmus, O. macronema and O. urbaini are verified in this study. Ompok macronema is hypothesized to be a junior synonym of O. hypophthalmus, and O. urbaini (previously considered a junior synonym of O. hypophthalmus) is hypothesized to be valid, distinct species. Ompok hypophthalmus is restricted to Java and the Barito River drainage in southern Borneo, and the material previously identified as O. hypophthalmus from Sumatra, the Malay Peninsula and Borneo represents O. rhadinurus, a new species.
