Etymology: Ompok: It is a bad reproduction of a Malayam fish name as limpok/ompok (Ref. 45335); brevirictus: From the Latin brevis meaning short, and rictus meaning an open mouth. The name is used in reference to the relatively short mouth of this species (correspondingly causing the mouth rictus to be separated from the anterior orbital margin by.

Ompok brevirictus can be distinguished from all Southeast Asian congeners, except for O. siluroides and O. miostomus, in having melanophores on the tympanic region forming a prominent black spot (vs. tympanic region dark, but without any melanophores forming a distinct spot). It differs from O. siluroides and O. miostomus in having an evenly convex predorsal profile (vs. with a concavity posterior to orbit) and a more prominent lower jaw that is more broadly curving. Ompok brevirictus additionally differs from O. siluroides in having the mouth rictus separated from the anterior orbital margin by a distance of more than one-third (vs. less than one-third) eye diameter (4.2–5.2% HL vs. 3.2–3.7) and lacking (vs. possessing) a distinct dark wedge-shaped spot on base of the caudal fin (Ref. 82371).
Body shape (shape guide): elongated.
