Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 24; Anal spines: 1; Anal soft rays: 23; Vertebrae: 26. This species is characterized by the following: D VI + I, 24; A I, 23; pectoral rays 22; cycloid scales, nonimbricate except posteriorly, about 152 oblique rows in longitudinal series; median predorsal scales absent; gill rakers 6 + 17; body depth 5.95 in SL; barbel on chin absent, only a low median fleshy ridge; a fringe of slender elongate papillae along side of lower jaw; first dorsal fin low, with curved spines, only the last with free tip; fifth dorsal spine longest, 1.85 in HL; caudal fin is slightly emarginate with rounded lobes, shorter than head, 4.9 in SL; pelvic fins short, 6.2 in SL; alcohol preserved specimens are pale tan with no dark markings except a faint dusky zone below nostrils between upper jaw and orbit; color of live individuals with two broad dusky stripes separated by a narrow pale midlateral stripe; lower dusky stripe expanding into a broad band in caudal fin, with a blackish spot at base; distal part of caudal fin yellow (Ref. 75638).
Collected from silty sand and rubble in 27 m depth in the lagoon (Ref. 75638).

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): 3.2 ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
