Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 9; Spine anali: 1; Raggi anali molli: 8. This species is distinguished from its congeners by the following characters: dark occipital spot, more well-developed in males and in preservation; an orange spot behind the eye in life; cephalic sensory-pore system pattern Group I (complete); dorsal/anal formula often 9/8; eye diameter 26.7-34.4% HL; caudal-peduncle depth 10.9-12.4% SL; 4th pelvic-fin ray with short, thick branches bound together by membranes (Ref. 79588).
Inhabits rocky caverns or coral heads on sand seen most frequently at depths of about 8-15 m on either live coral (frequently faviids) or on rocky surfaces covered with coralline algae patches (Ref. 79588).
