臀鳍软条: 193 - 222. Distinguished from other congeners in having the following combination of characters: gape relatively long and rictus extending posteriorly beyond the vertical through the posterior naris; length of coronomeckelian bone less than 20% the length of Meckel’s cartilage; length of the posterior ceratohyal 1.5 times the length of the ventral hypohyal; approximately six irregularly distributed teeth on the internal surface of the endopterygoid; anteroposterior length of premaxilla greater than the transverse width; teeth on the dentary restricted to the anterior half or slightly more of the dorsal margin; depth of the caudal filament 5.0-6.5% CL; presence of a narrow dark stripe along the lateral line and a broad dusky to dark band of pigmentation overlying the basal pterygiophores of the anal fin; pectoral-fin rays 19-22; total number of anal-fin rays 193-222 (Ref. 93148).
Its elongated, laterally compressed body is completely covered with scales and is without a caudal fin (Ref. 27188).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00363 (0.00172 - 0.00768), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (34 of 100).
