簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 15 - 17; 背的軟條 (總數): 7-9; 臀棘 5-6; 臀鰭軟條: 6 - 7; 脊椎骨: 26. Differs from all species of the genus by the following combination of characters: 5-6 anal-fin spines; 6-7 branched anal-fin rays; caudal peduncle length 8.9-11.8% of SL; lips not thickened; in preserved specimens lateral band formed by two series of scales, each scale bears a dark spot in the centrum, between both scales there is a light narrow area; dorsal, anal and caudal fins, and opercle without dark spots (Ref. 57794).
在組合特徵之後有別於本屬的所有種藉由: 5-6 臀鰭棘; 6-7 分枝臀鰭棘條; 尾柄長度 8.9-11.8% 的 SL; 唇沒有變厚; 在保存的標本側面的條紋中由二個成列的鱗片形成了,每個鱗片有在椎體的一個深色的斑點, 在兩者的鱗片之間有一個淡的狹窄區域; 背鰭、臀鰭與尾鰭 , 與鰓蓋沒有深色的斑點。 (參考文獻 57794)
