soft rays: 8 - 9. This species is distinguished by the following characters: body moderately deep, its depth 2.6-3.1 in SL; preopercular notch and knob poorly developed; vomerine tooth patch crescentic, without a medial posterior extension; tongue with a patch of granular teeth; gill rakers of first gill arch 6 + 8-10 = 14-16.

Adults inhabit both inshore and offshore coral reefs where they occur singly or in schools. Small juveniles on shallow protected reef flats and are used in the aquarium trade.
