'Proterochampsa' nodosa (De Disao-Oliveira, Pinheiro, De Andrade and Pretto 2022, Late Triassic) was originally considered a species of Proterochampsa . Here it nests with Pseudochampsa.

Pseudochampsa ischigualastensis (Trotteyn and Ezcurra 2014, PVSJ 567, Museo de
Ciencias Naturales, Universidad Nacional de San Juan) Middle-Late Triassic (late Carnian–earliest Norian), ~ 240 mya was originally considered a species of Chanaresuchus. Distinct in size, the foot is also distinct.
