Spine dorsali (totale) : 8; Raggi dorsali molli (totale) : 10 - 12; Spine anali: 1; Raggi anali molli: 10 - 11. Dorsal rays VII + I, 11 (10–12, rarely 10); anal rays I,10 (10–11, two of 15 with 11); pectoral
rays 17–19 (usually 18, one of 30 with 19); no scales; body and fins covered with thick adherent mucus; mouth subterminal; tongue truncate; no rostral frenum; color in alcohol pale yellowish gray with a midlateral black stripe from eye nearly to posterior end of caudal fin, about a pupil diameter in width on head, broadening to about an eye diameter in width on body; a blackish line extending posteriorly from above upper edge of eye, continuing below base of dorsal fins, and extending into dorsal part of caudal fin; fins otherwise translucent gray; color in life of body above black lateral stripe bluish to greenish gray with a bright white stripe as wide as pupil passing between black stripe and black line, becoming yellow on head as it nears upper edge of eye; dorsal part of iris brilliant yellow; snout and lips dusky yellow; a median brilliant yellow band on snout extending into anterior interorbital; ventral part of head and body whitish (Ref. 81169).
Collected with a hand net from a patch reef of mixed coral and sponge on sloping sand substratum at 5 m (Ref. 81169).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
