簡短描述
檢索表 | 型態特徵 | 形態測量圖
脊椎骨: 43. Can be diagnosed by a combination of the following characters: rays on dorsal and ventral lobes of caudal fin with fused branches or not separated as in other species of Pseudoplatystoma; wide straight, dark vertical bars on sides; absence of loops on nape and associated areas; dorsal and ventral regions of pectoral fin pale with no spots; dorsal fin with few or no spots (sometimes 5 spots); 43 vertebrae; adipose fin with 6-7 large spots; areas surrounding the procurrent rays of dorsal fin without spots; posterior region of the metapterygoid wider than in other species, forming a depression or notch in the dorsal margin of the suspensorium (Ref. 59362).
能被下列特徵的一個組合鑑定: 在背部與腹葉上的鰭條尾鰭有融合的分支在其他種的 Pseudoplatystoma 區分為; 在側邊上的寬的直又深色的縱帶; 在後頸與相連的區域上缺乏環; 胸鰭的背部與腹區域灰白的沒有斑點; 背鰭有很少或沒有斑點;(有時 5個斑點) 43個脊椎骨; 脂鰭有 6-7 大的斑點; 區域圍住沒有斑點的背鰭的前流鰭條; metapterygoid 的在後部區域在其他的種方面寬, 在 suspensorium 的背部邊緣中形成一個凹窪或凹槽。 (參考文獻 59362)
