caudal fin is emarginate to rounded. The origin of the dorsal fin is slightly in advance of the origin of the pelvic fin. The pectoral and pelvic fins are directed laterally, each with a single unbranched ray. In B. diabolica , large tubercles are arranged irregularly on the posterior lower half of the flank, especially above the anal fin and caudal peduncle.

This article aims to describe an additional, conspicuously different and miniature species of Barbucca from the Kahayan drainage, Borneo.
