Issue
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.

Occurs throughout the principal riverbeds and sometimes in the flooded areas of forests. Its biology is similar to that of P. tigrinum but it appears to be more fond of shady streams. Feeds at night on fish (loricariids, cichlids and characoids) as well as crabs (Ref. 6868). Confines its foraging activities to riverbeds. Its 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.
在主要的河床各处发生与有时在森林的洪泛区中。 它的生物学特性是类似 P. tigrinum 但是它状似更喜欢的暗溪流。 晚上捕食鱼 (甲鲶科，慈鲷科鱼类与脂鲤类) 以及螃蟹.(参考文献 6868) 觅食活动局限于河床。 它的淡黄色肉其他鲶鱼是多汁而相似的那, 它没有硬骨。 (参考文献 27188) 雌性达到一个比较显着的大小。 他们在 56 公分时性成熟了, 在 45 cm 的雄性。 孕卵数被估计每公斤八百万个卵。 (参考文献 35381) 供人类食用。
