Taxonomic Remarks
Considered as species inquirenda by some authors. Junior synonym Platystoma punctifer (Buitrago-Suárez, 2006:120) is considered valid by Buitrago-Suárez & Burr, 2007 (Ref. 59362). This species record will be modified.

簡短描述
檢索表 | 型態特徵 | 形態測量圖
Adults occur throughout the principal riverbeds and sometimes in the flooded areas of forests. Their biology is similar to that of P. tigrinum but appear to be more fond of shady streams. They feed at night on fish (loricariids, cichlids and characoids) as well as crabs (Ref. 6868). Foraging activities are comfined to riverbeds. The yellowish flesh is succulent and like that of other silurids, it is without bones (Ref. 27188). Females reach a more notable size. They become sexually mature at 56 cm, males at 45 cm. Fecundity is estimated at 8 million eggs per kg (Ref. 35381). Utilized for human consumption. See Loubens and Panfili, 2000 (Ref. 34213) for reproductive biology and ecology.
在主要的河床各處發生與有時在森林的洪泛區中。 它的生物學特性是類似 P. tigrinum 但是它狀似更喜歡的暗溪流。 晚上捕食魚 (甲鯰科，慈鯛科魚類與脂鯉類) 以及螃蟹.(參考文獻 6868) 覓食活動侷限於河床。 它的淡黃色肉其他鯰魚是多汁而相似的那, 它沒有硬骨。 (參考文獻 27188) 雌性達到一個比較顯著的大小。 他們在 56 公分時性成熟了, 在 45 cm 的雄性。 孕卵數被估計每公斤八百萬個卵。 (參考文獻 35381) 供人類食用。
