Dorsal spines (total): 1; Dorsal soft rays (total): 5; Anal soft rays: 9 - 10; Vertebrae: 31 - 32. Diagnosed by the following characters: space between anterior nostril and base of nasal barbel about equal to nostril diameter; anterior and posterior nostrils relatively small (diameter less than that of eye); anterior nostril located at end of short tube; jaws subequal (lip of upper jaw projecting past lower jaw); caudal fin emarginate (not strongly forked); eye dorsolateral, not protruding above head when viewed from side; large depression below eye; posterior edge of pectoral spine with three small serrae (much less than half width of spine); and top of head flat, lacking conspicuous concavity and bony ridges (Ref. 75761).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.6 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
