Etymology: Pseudoplatystoma: Greek, pseudes = false + Greek, platys = flat + Greek, stoma = mouth (Ref. 45335).

Issue
We believe based on the original description, plate, and locality that Platystoma truncatum is a synonym of Pseudoplatystoma tigrinum. We have retained the younger name P. tigrinum (Valenciennes, 1840) for purposes of stability, there has been virtually no use of P. truncatum since its original description, thus we treat it as a Nomen oblitum. For reproductive biology and ecology, see Loubens and Panfili (2000).

Краткое описание
определительные ключи | морфология | морфометрия
Occurs in estuarine zones, mainly upstream of the first rapids up to the basin's headwaters. Nocturnal species which lives in the main bed of slow or fast zones, as well as in the flooded forests, particularly the juveniles., Opportunistic, piscivorous fish which may feed on crabs and shrimps. At the end of the dry season, they can migrate at the same time as their prey, then return at the end of the rainy season (Ref. 35381). Most important catfish in gill-net fisheries of Guaporé and Mamoré rivers.
