簡短描述
型態特徵 | 形態測量圖
Distinguished from all congeners by the following combination of characters: upper jaws projects more strongly forward, premaxillary teeth exposed when the mouth is closed; head width 18.2-19.4 % SL, body depth at anus 10.7-11.5 % SL, depth of caudal peduncle 6.5-6.7 % SL, interorbital distance 32-34 % HL, length of maxillary barbels 104.110 % HL; 5 teeth on posterior edge of pectoral spine, and a color pattern of a dark background with light patches.
在組合特徵之後與所有的同類區分了藉由: 當嘴巴被關閉的時候,上顎計畫更強烈向前又上頜骨前的齒暴露出來; 頭部寬度 18.2-19.4% SL, 在肛門 10.7-11.5% SL ,尾柄 6.5-6.7% SL ,眼間距 32-34% HL 的深度的體高, 顎觸鬚 104.110 的長度 % HL; 5 牙齒在胸棘的後緣, 與深色背景的一個彩色斑紋有淡色的區塊。
