Conspicuous white spot behind tip of each dorsal spine (Ref. 26938). Body slender. Upper jaw extending posteriorly to middle of pupil (Ref. 37108). Body bright red or red striped, sometimes blotched (Ref. 7251). Similar in color to H. ascensionis, but each interspinous membrane of dorsal fin with a white spot near margin (Ref. 13442).

Nocturnal (Ref. 37108), inhabits clear reefs (Ref. 5217). Found near mouths of caves and holes (Ref. 26938); at night they usually move to sandy areas and grass beds to feed on crabs, shrimps, gastropods and brittle stars (Ref. 3724). Marketed fresh but not popular as a food fish (Ref. 5217).
