Duri punggung (Keseluruhan (total)) : 1; vertebrata, bertulang belakang: 34 - 35. Distinguished from all congeners in having highly elevated supraoccipital spine and nuchal plate. Differs further from congeners in having a unique combination of the following characters: highly contrasting light brown patches on a chocolate brown body; lack of filamentous extensions to the first pectoral-fin element; presence of 5-6 serrations on the posterior edge of pectoral spine; eye diameter 6-9% of head length; branchiostegal membranes meeting at isthmus ventrally; outer mandibular barbels reaching middle of pectoral-fin base; and rounded tubercles on the tip of the snout and dorsal surface of neurocranium (Ref. 55975).
