Morphology | Morphometrics
soft rays: 8. Second dorsal fin with 1 spine and 9 soft rays; second dorsal spines filamentous in males. Anterior nasal tube elongate, 10-15% HL, black except at extreme base. An oblique black spot behind orbit, followed by 2 black vertical bars on each side of the nape. Presence of an anterior and, usually, a posterior interorbital pore; a postocular and an infraorbital pore; preopercular pores absent (Ref. 39927); characterized further by longitudinal scale series 24; ctenoid scales on body except cycloid near midline of abdomen and anterolaterally behind lower pectoral fin base; scaleless head, nape, pectoral fin base and breast; depth of body 4.3 in SL (Ref. 90102).
Inhabits reef crevices 10-30 m (Ref. 90102).
