Các tia vây lưng cứng (tổng cộng) : 0; Các vây lưng mềm (tổng cộng) : 26; Tia cứng vây hậu môn: 0; Tia mềm vây hậu môn: 40; Động vật có xương sống: 67. Two terminal bulbs separated by a short interspace, shorter than length of distal bulb. Barbel 68% SL. Terminal filament long (20%), with a series of 5 long branches beginning a short distance (a distal bulb length) from bulb, all with small bulblets, none of which approaches the diameter of the filament. All branches with 1 or more short branches. Stem axis peppered with melanophores; lightly pigmented on axis between bulbs and in proximal part of filament. Number of middorsal paired spots under skin uncertain (obscure and diffuse in holotype) (Ref. 11333).
Known based on a single specimen taken at a depth between 0-112 m.
