Infrafamily Peiropemydodda , new

DIAGNOSIS: Members of the subfamily Podocnemidinae ; cheek emargination reaches above level of orbit; characters also found in Bauruemys : medial expansion of triturating surface absent; accessory ridges absent from the triturating surface.

DISTRIBUTION: Late Cretaceous of Brazil, Paleocene of Bolivia.

INCLUDED TAXA: Peiropemys , n. gen.; Lapparentemys , n. gen.; Pricemys , n. gen.

DISCUSSION: This grouping of three genera that are outside the common ancestor of the living species in our analysis really rests only on the combination of the smaller cheek emargination, as the absence of the medial expansion of the triturating surfaces with accessory ridges is primitive for the family. One step away from the shortest cladogram makes this group a multichotomy with Podocnemis and the magnatribe Erymnochelydand.
