Diagnosis

Diagnosis: a frontal ridge behind the orbits that slopes steeply into a wide interorbital trench

anteromedially, and into postorbital trenches laterally; posterior nasal opening separate from eye; second spine of first dorsal fin elongate, third spine occasionally elongate; fifth pelvic fin ray branched once dichotomously; body color orange-red with seven dorsolateral white spots

between posterodorsal margin of the peduncle and origin of first dorsal, and with four ventrolateral spots between posteroventral margin of peduncle and origin of last anal ray; facial pattern uniform dusky orange-grey colour under orbit, with an orange vertical blotch, edged in melanophores on vertical limb of the preopercle resembling a club; conspicuous bar of melanophores extending vertically across posterior margin of pectoral base (Ref. 57688).
