背面の脊椎 (合計) : 13 - 14; 背鰭 (合計) : 9 - 11; 肛門の骨: 3; 臀鰭: 7 - 9; 脊つい: 28. This species is distinguished from all congeners by the following characters: bright yellow color pattern of the unpaired fins (vs. mostly red in other species); covered with white dots aligned between rays; distal border of the dorsal fin and dorsal and ventral contours of caudal fin red with thin light stripes; prominent adipose hump in mature males, extending dorsally above the tip of the longest dorsal-fin spines (vs. less developed) (Ref. 118066).
