摘要
A Neogene turtle from Brasil is described. It represents the first find of a new species close to the extant Podocnemis sextuberculata. Both species constitute a new clade in the genus. The synapomorphies they share and the differences between them are given. R negrii nov. sp. is the second fossil species of the genus, after P. bassleri from the Neogene of Peru, which constitutes another clade with the extant R expansa. The relationships between these two clades and the other species of the genus are not determinate. (C) 2002 Editions scientifiques et medicales Elsevier SAS. All rights reserved.
