Dorsal fin I-II, 13-16; Anal fin I-II, 12-13; Pectoral fin 10-14; Pelvic fin 4-6; Caudal fin 19-20; Procurrent rays 9-10/9-11; Gill rakers 13-14 + 1 + 5-7; Vertebrae 10-11 + 21-23 = 32-34. Body relatively short, robust, greatest depth around level of pectoral fins, three times in SL. Trunk sub-oval in cross-section, as broad as head anteriorly. Dorsal-fin origin in posterior half of body, fin base overlaps anal fin entirely, with two spines and three dorsal rays anterior to anal fin origin. Anus at anal fin origin. Pelvic fin bases approximately midway between level of pectoral and dorsal fins. Caudal peduncle moderate in length, 22–27% LS (inclusive of procurrent rays). Scales thin, smooth, cycloid, deciduous, mostly absent from head (few on preopercle). |
