簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 1; 背的軟條 (總數): 6; 臀鰭軟條: 25 - 30; 脊椎骨: 39 - 40. Readily distinguished from other members of the genus by its color pattern consisting of a dark brown dorsum, speckled to dark sides, light venter, pale fins and a large dark spot on the basal half of the dorsal fin. Among the smallest species in the family, maturing between 30-40 mm SL.
