Morphology | Morphometrics
soft rays: 52 - 61;
Vertebrae: 40 - 44. This species is characterized by the following: Vertebrae 11-13 + 29-32 = 40-44, dorsal fin rays 71-82, anal fin rays 52-61; outer pseudoclasper wingshaped with single curved supporter anteriorly; inner pseudoclasper club-shaped, with prominent appendix inserted at posterior-distal angle; small fleshy lobe at base of hood adjacent to outer pseudoclasper, penis
tapering; opercular spine with single, sharp tip; scale patch on cheeks with 6-9 vertical scale rows; otolith length: height ratio 2.2-2.3; green pigment globules in head and body mucus (Ref. 57883).
Inhabits rocky and coral reefs, in depths down to about 15 m. A few specimens are known from mangrove habitats. A 58 mm SL female specimen contains about 50 eggs, diameter 0.3-0.5 mm and 55 embryos, 6-8 mm TL, with 2 long rows of pigment spots along mid-body and dorsal fin base (Ref. 57883).
