簡短描述
檢索表 | 型態特徵 | 形態測量圖
脊椎骨: 39 - 41. Can be differentiated by a combination of the following characters: well defined straight vertical bars along the side of body, longer than those of Pseudoplatystoma fasciatum and Pseudoplatystoma punctifer; bars connecting to, or extending to, the dorsal region and continuing onto other side of body; vertical bars of anterior region straight and extending below dorsolateral dusky area; usually no spots below lateral line, some individuals with two or three spots; 39-41 vertebrae (Ref. 59362).
能被藉由下列特徵的一個組合區別: 很清晰直的縱帶沿著身體側邊，長度超過 Pseudoplatystoma fasciatum 的與 Pseudoplatystoma punctifer; 橫帶連接到, 或延伸至, 背部區域而且延伸到其他的身體側邊; 前面區域直線的縱帶而且向下延伸背外側的暗色區域; 通常沒有斑點在側線下, 一些個體有兩個或三個斑點; 39-41個脊椎骨.(參考文獻 59362)
