Dorsale zachte stralen (totaal) : 72 - 88; Anale zachte stralen: 55 - 70; Wervels: 40 - 45. This species is distinguished by the following characters: D 72-88; A 55-70; moderately large eyes (1.7-2.8%SL); slender body; blunt snout, many cirri; cheeks with scales and rarely 1-2 scales above opercular spine; with upper preopercular pore; outer pseudoclasper broad-based, large, often extending beyond hood when in resting position, while the inner one is small, with equal anterior and posterior lobes; otolith length to height 1.9-2.1, with gently curved dorsal rim; otolith length to sulcus length 1.5-1.6, ostium length to caudal length 3.5-4.5; vertebrae 11-12 + 29-33 = 40-45 (Ref. 81230).
Occurs in holes and crevices of coralline and volcanic rock (Ref. 71230). Cryptic and solitary in shallow water (<12 m) (Ref 90102).
