簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 0; 背的軟條 (總數): 0; 臀鰭軟條: 90 - 101; 脊椎骨: 63 - 64. Snout with a gently sloping ventral profile (ventral angle of snout 40°-42°), relatively fewer anal-fin rays (90-101), and larger eyes (eye diameter 13.0-16.4% HL) set closer together (interorbital distance 33.7-36.6% HL). Mature males have membranous extensions on both the anterior and posterior edges of the maxillary barbel. Pectoral spine and articulated segments sexually dimorphic in mature individuals. Males with spine broad and somewhat flattened dorsoventrally, with 10 distinct posterior serrate, increasing in size distally; proximal articulated segments with 17 well-developed posterior serrae; distal-most segments have smaller serrae. Females or juveniles with spine slender and without serrae; proximal articulated segments with 6 minute posterior serrae; distal segments with 5 minute serrae (Ref. 38651). Absence of dorsal fin; short stiff hooked maxillary barbels; posterior nostril above front margin eye (Ref. 43281).
吻部有被設定的一個緩斜坡的腹輪廓 (吻的腹面角 40 °-42 °) ，相對較少的臀鰭棘條 (90-101) 與比較大的眼 (眼直徑 13.0-16.4% HL) 比較靠近的一起 (眼間距 33.7-36.6% HL). 成熟的雄魚有顎觸鬚的膜狀的延長在前緣與後緣。 胸棘而且接合片段性別雙型性在成熟的個體中。 雄性有棘寬的而且略微有背腹性地平的, 具有 10 明顯的在後部的鋸齒狀的, 末梢部地在大小方面增加; 具有 17個發展良好的在後部鋸齒的近端被接合的片段; 末梢部-大多數的片段有小的鋸齒。 雌性或稚魚有棘細長的而且沒有鋸齒; 近端的被接合的片段 6 細小的在後部的鋸齒; 末梢部的片段 5 細小的鋸齒。 (參考文獻 38651) 沒有背鰭; 短的硬鉤上頜骨觸鬚; 在眼睛前緣上面的後鼻孔.(參考文獻 43281)
