簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 4 - 6; 背的軟條 (總數) : 53 - 55; 臀棘: 3; 臀鰭軟條: 47 - 51; 脊椎骨: 73 - 76. Belongs to the Macrognathus aculeatus species group but can be distinguished from all other Asian mastacembelids by having only 4-6 spines on dorsal fin (vs. 11-40). Differs further from all members of the Macrognathus aculeatus species group by having only 6-8 rostral tooth plates (vs. 9 in Macrognathus meklongensis to 55 in Macrognathus tapirus) and the details of color pattern (Ref. 83418).
