背棘 (總數) : 0; 背的軟條 (總數) : 22 - 26; 臀棘: 0; 臀鰭軟條: 32 - 37. A single, very small terminal bulb 0.3-0.6% SL. Barbel short 20-35% SL in specimens over 8 cm and some smaller ones, shorter in some developing specimens up to about 8 cm. Three pairs of short filaments; each filament of 1 pair with a prominent, elongate distal bulblet that may be larger than the terminal bulb; a pair slender , with closely spaced very small bulblets; a pair simple, with few or no occlusions, and usually the longest. Axis of stem moderately pigmented, becoming darker before bulb and very dark over 1 side of bulb, where pigment forks and extends along axis of the pair of filaments with large bulblets. External chevron-shaped or roundish striated areas unpigmented. Dorsal paired spots between occiput and dorsal-fin origin 9 or 10 (rarely 7 or 8) (Ref. 11333).

Estimates based on models
Preferred temperature (Ref.
123201): 9.2 - 21.3, mean 14.1 °C (based on 367 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00116 - 0.00786), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
