背的软条 (总数) : 1; 臀鳍软条: 70 - 79; 脊椎骨: 57 - 59. Pectoral fin length 14.0-16.9% SL; pectoral spine length 9.0-11.0% SL; eye diameter 20.0-23.9% HL; vomerine teeth present in two closely-situated elliptical patches; a distinct nuchal concavity; and mandibular barbels reaching beyond anterior base of anal fin. Pectoral spine and articulated segments sexually dimorphic in mature individuals. Male with spine broad and somewhat flattened dorsoventrally, with 10-12 distinct posterior serrations; proximal articulated segments with 9-18 well-developed posterior serrations. Females with spine slender, with 12-14 smaller posterior serrations; proximal articulated segments with 6-9 small and poorly-developed posterior serrations. Fins hyaline, with small dark-brown spots occasionally present (Ref. 42937).
Body shape (shape guide): elongated.
胸鳍长度 14.0-16.9% SL; 胸棘长度 9.0-11.0% SL; 眼直径 20.0-23.9% HL; 犁骨齿出现在二接近地-位于椭圆的区块; 一个明显的颈背凹洼; 而且超过前面的臀鳍基底鳍的颚骨触须。 胸棘而且接合片段性别双型性在成熟的个体中。 雄鱼有棘宽的而且略微有背腹性地平的, 与 10-12 明显的在后部的锯齿; 用 9-18个发展良好的在后部锯齿的近端被接合的片段。 雌鱼有棘细长的, 藉由 12-14个比较小的在后部的锯齿; 近端的被接合的片段 6-9个小的与发展不良的在后部的锯齿。 鳍透明的, 有小的深褐色的斑点偶然存在.(参考文献 42937)
