| Resumen: |
In this paper, a new species of Vasseuromys, V. bergasensis sp. nov., from the locality of Bergasa (Ebro Basin, Spain), is described. Bergasa contains a fauna belonging to the Late Oligocene (zone MP30), composed— among other species—of Issiodoromys pseudanaema and Rhodanomys transiens. The main diagnostic features of V. bergasensis sp. nov. are the presence of a long centrolophid (fused or not to the mesoconid) in the lower molars, a large reduction in thenumber and length of extra ridges in the upper and lower molars, the absence of extra ridges between metalophid and centrolophid and between centrolophid and mesolophid, and the absence of the metatrope in more than half the specimens of the upper teeth M1 and M2. V. bergasensis sp. nov. is similar in size to V. elegans and smaller than the other members of the genus. The age and simple dental pattern of the new species of Vasseuromys allow us to hypothesize about relationships within the genus. |
