簡短描述
檢索表 | 型態特徵 | 形態測量圖
臀棘: 0; 臀鰭軟條: 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).
在最後的鰓弓上的總鰓耙 11-14。 眼直徑 8.9-15.3% HL。 由於它的類似 A. midgleyi, 剩餘的鑑別參考依據為 A. midgleyi 和 A. paucus: 一個光滑的身體; 強的顎; 顎朝上的些微地在癒合處, 嘴寬的; 吻截形的輪廓; 頭部長方形, 它的寬度平均 66% HL。 上枕骨突起狹窄的有平行的邊緣。 很多的細, 銳利的在四個長方形群的橫跨條紋中牙齒在上顎。 沒有耙鰓弓的在後部面。 觸鬚細又短的, 很少地超過胸鰭基底而且少於 25% SL.(參考文獻 40908)
