Dorsal soft rays (total): 76 - 81; Anal soft rays: 62 - 65; Vertebrae: 42 - 43. The species is characterized by the following: vertebrae 11+31-32=42-43, dorsal fin rays 76-81, anal fin rays 62-65; large eyes (2.4-2.5% SL); lower preopercular pores 1; outer pseudoclasper narrow wing-shaped, moderately long; inner pseudoclasper a long thin flap, anteriorly joined to outer pseudoclasper forming a u-shaped structure, with supporter; moderately broad scale patch on cheek with 5-7 scale rows on upper cheek, no scales on operculum; the head profile with a stubby snout (Ref. 57884).

Solitary in reef crevices to 33 m, cryptic (Ref 90102).
