简单描述
型态特徵 | 形态测量图
背棘 (总数): 1; 背的软条 (总数): 9; 臀鳍软条: 10 - 11. Head smooth above (Ref. 2988). Maxillary barbel reaching middle of adipose fin in the young and the end of the rayed dorsal in the adult; nasal barbel reaching anterior border of eye (Ref. 52301, Ref. 2988). External mandibular barbels reaching the branchial fissure; occipital processus reaching the interneural bone (Ref. 52301). Longest dorsal fin ray a little longer than head; distance between adipose and dorsal fin equals base of the latter; adipose fin twice as long as the distance between dorsal and adipose fin (Ref. 2988). Caudal fin forked, upper lobe slightly the longer (Ref. 52301, Ref. 2988). Pectoral spine very strong, prominent and strongly serrated (Ref. 36900) on inner side (Ref. 2988). Pelvic fins under last dorsal fin ray (Ref. 52301, Ref. 2988).
Coloration: reddish brown above, yellowish white beneath and the caudal fin dotted with black (Ref. 36900, Ref. 2988).
头部平滑的上方.(参考文献 2988) 上颌骨触须在成鱼中达到幼鱼与有鳍条的背鳍的末端的脂鳍的中央; 鼻骨触须达到眼的前缘。 (参考文献 52301, 参考文献 2988) 外部的颚触须达到鳃的裂缝; 后头骨活动达到背侧间的硬骨。 (参考文献 52301) 长的背鳍鳍条稍微长度超过头部; 脂鳍与背鳍等于后者的基底之间的距离; 脂鳍两倍长于那背鳍与脂鳍鳍之间的距离.(参考文献 2988) 尾鳍分岔, 上叶些微地比较长.(参考文献 52301, 参考文献 2988) 胸棘非常强的, 突出的而且在内部的側邊上深鋸齒狀的 (參考文獻 36900).(參考文獻 2988) 在最後的背鰭鰭條下面的腹鰭.(參考文獻 52301, 參考文獻 2988)
體色 紅褐色的上方, 黃白色在與之下尾鰭有黑色斑點.(參考文獻 36900, 參考文獻 2988)
