背面の脊椎 (合計) : 0; 背鰭 (合計) : 26; 肛門の骨: 0; 臀鰭: 40; 脊つい: 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).
Body shape (shape guide): elongated.
Known based on a single specimen taken at a depth between 0-112 m.
