Morphology | Morphometrics
soft rays: 8. This species is distinguished by the following characters: scales in the predorsal midline; no scales on the cheek or opercle; elongated second spine of the first dorsal fin reaching to the bases of the 2nd-8th second dorsal-fin rays when adpressed; unbranched pectoral-fin rays; fifth pelvic-fin ray branched with a full basal membrane; when fresh, yellow bars on the head and vertically elongate yellow spots on brown body (Ref. 119765).
This species appears to be a rare species, with seven specimens collected mostly between 10-16 m. Found living under large pieces of dead foliose coral rubble on a sandy bottom subject to moderate currents and wave action. It is apparently a solitary species, only a single specimen collected from each piece of rubble examined (Ref. 119765).
