Morphology | Morphometrics
soft rays: 8. This species is distinguished by the following characters: diagonally slanting grey and yellow bars on body; nape scaled with about 5-6 predorsal scales; pectoral fin with 16-17 unbranched rays; unbranched fifth pelvic-fin ray, about half length of fourth ray; interorbital region with a U-shaped trench and no postorbital trenches (Ref. 112075).
Its cryptic habits and small size make it difficult to observe and collect this species (Ref. 112075).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00427 - 0.01860), b=3.08 (2.91 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
