Morphology | Morphometrics
(total): 6 - 7;
soft rays: 8. Diagnosis: Distinguished by the combination of following features: predorsal scales absent; anterior extension of body scales up to the shoulder spot; body light brown with large orange spots or stripes on the head; a dark greyish-orange shoulder spot above the pectoral fin base; and a grey iris with several orange spots. These orange spots on head are grading to red on the branchiostegal membrane (Ref. 51083); characterized further by having longitudinal scale series 23-25; cheeks and opercle without scales; depth of body 3.8-4.2 in SL (Ref. 90102).
Inhabits outer reef caves and crevices in 5-20 m (Ref. 90102).
