Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 10; Dorsal soft rays (total): 15; Anal spines: 3; Anal soft rays: 7; Vertebrae: 26. This species is distinguished from its congeners by the following set of characters: D X,5, fourth dorsal-fin spine longest and no fleshy flaps on dorsal-fin spines; pectoral rays 13, all unbranched; branched caudal-fin rays 8 + 7; lateral line scales 28 (including intermittent and terminal pitted scales); circumpeduncular scales 12; preopercle without antrorse spines or serrations ventrally, with 2–3 weak serrations or crenulations posteriorly (Ref. 117635).
Cross section: compressed.
This species is only known from Izu Ocean Park, where it has been collected and photographed on rocky reefs at depths of 48-60 meters (Ref. 117635)
