soft rays: 8. This species is distinguished by the following set of characters: D VI + I,7- 8, the second and third spines are the longest, with short filamentous tips reaching to between bases of first two segmented rays of second dorsal fin when adpressed; A I,8; pectoral rays 16, all are unbranched; pelvic fin I,5 with the fifth pelvic ray unbranched, 48-55% length of fourth pelvic ray; bony interorbital 53-65% pupil diameter; nape fully scaled with 12-13 scales on midline of predorsal; cheek and opercle covered with scales; scales ctenoid on breast (prepelvic); a prominent dark bar at caudal-fin base and scale pockets are strongly outlined with melanophores (Ref. 100512).
Found in caves and ledges in 107 m depth at the baseof a steep outer reef slope (Ref. 100512).

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=0.00631 (0.00289 - 0.01377), b=3.09 (2.90 - 3.28), 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) .
