Taggstrålar i ryggfenan (totalt) : 18 - 8; Mjukstrålar i ryggfenan (totalt) : 10 - 12; Taggstrålar i analfenan: 1; Mjukstrålar i analfenan: 21 - 23.
Adults are found among exposed boulders of rocky coasts in two volcanic islets in Banda Sea (Ref. 8927, 90102). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
