| Diagnosis |
This species is distinguished from its congeners by the following set of characters: broad laminar, ribbon-shaped nasal barbels; maxillary and rictal barbels broad at their basal portion, abruptly narrowing distally; large skin papillae on the ventral surface of the head; longer maxillary and rictal barbels, their tips posteriorly reaching the anterior region of the interopercular patch of odontodes; mouth subterminal; and the anal-fin origin at a vertical through the posterior portion of the dorsal-fin base (Ref. 128385). |
