This species is distimguished by the following characters: D VI + I,10; A I,9; pectoral-fin rays 14, all rays branched; pelvic-fin rays I,5, fin separated and no frenum, fifth ray unbranched; snout short, its length 0.7 of eye diameter; anterior nostril with a long nasal tube without process from the rim, posterior nostril pore with slightly erected rim; absence of tentacle above eye; posterior angle of jaws extending posteriorly to below posterior edge of pupil; opercular spine absent; without mental frenum; pelvic fins ending at anus, longer than pectoral fin; squamation reduced to a few ctenoid scales on caudal peduncle at caudal-fin base; absence of head canals; suborbital rows of papillae with 4 transverse rows; 3 distinct preorbital rows s present from posterior nostril to above upper lip; suborbital row 3 short, extending from eye ending distantly from row d; suborbital row 4 long, curving at ventroposterior edge of eye, extending obliquely below of level of row d; suborbital row b anteriorly not reaching to below posterior edge of eye; anterior dorsal rows o and m are present. Colour of head when alive and fresh orange, with body yellowish orange and with 5 faint, vertical, brown bands (Ref. 121824).
This species is known only from the holotype which was collected at 14-16 m depth, from a steep coral-reef sloping down to about 30 m depth, where the upper half of the slope with short steps covered with hard and soft corals, and the specimen was collected at the entrance of small with cave (Ref. 121824).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.0 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
