soft rays: 9;
Vertebrae: 33 - 34. 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).
