臀棘: 0; 臀鳍软条: 16 - 19; 脊椎骨: 55 - 57. Total gill rakers 11-14 on last arch. Eye diameter 8.9-15.3% HL. Because of its similarity to A. midgleyi, the remaining diagnosis refers to both A. midgleyi and A. paucus: a sleek body; strong jaws; jaws upturned slightly at symphyses, mouth broad; snout truncate in profile; head oblong, its width averaging 66% HL. Supraoccipital process narrow with parallel margins. Numerous fine, sharp teeth on palate in transverse band of four oblong groups. No rakers on posterior aspect of gill arches. Barbels thin and short, rarely reaching beyond pectoral fin base and less than 25% SL (Ref. 40908).
在最后的鳃弓上的总鳃耙 11-14。 眼直径 8.9-15.3% HL。 由于它的类似 A. midgleyi, 剩余的鉴别参考依据为 A. midgleyi 和 A. paucus: 一个光滑的身体; 强的颚; 颚朝上的些微地在愈合处, 嘴宽的; 吻截形的轮廓; 头部长方形, 它的宽度平均 66% HL。 上枕骨突起狭窄的有平行的边缘。 很多的细, 锐利的在四个长方形群的横跨条纹中牙齿在上颚。 没有耙鳃弓的在后部面。 触须细又短的, 很少地超过胸鳍基底而且少于 25% SL.(参考文献 40908)
