خارهاي باله پشتي (کل): 2; شعاع نرم باله پشتي (کل): 0; خارهاي باله مخرجي 0; شعاع نرم باله مخرجي: 0. Recognized by its tremendous, mandarin-like nasal barbels (Ref. 247).
Found on the uppermost continental and insular slopes, and probably the outer continental-insular shelves (Ref. 31367). Probably feeds on bottom fishes and some invertebrates (Ref. 247).
