Morphology | Morphometrics
soft rays: 8. Diagnosis: Pelvic fins widely separated at base, rays I,5, fifth ray unbranched, distance between bases of inner rays of two fins about equal to base of either fin. Head pore 1 by each posterior nostril, a single anterior interorbital pore, a single posterior interorbital pore, a supraorbital pore behind eye, an infraorbital pore below supraorbital pore behind eye, a lateral canal pore behind infraorbital pore, a terminal lateral-canal pore over preopercular margin, and two preopercular pores. The first gill-arch is connected by membrane to inside of gill cover. The gill opening restricted to depth of pectoral base. Anterior nostril tubular; posterior nostril a simple pore or with slightly elevated anterior rim. In males, the first two dorsal spines prolonged or not. First dorsal fin without prominent black spots or dark lines, often with small brown irregular marks near the base of the fin. A black spot subequal to pupil diameter is found behind the eye. Second dorsal-fin rays I,8 (Ref. 57078).
Collected in rocky areas with some coral (Ref. 57078).
