摘要：
A new subgenus, Pseudoleptarctus, is described on the basis of a mandible from the late Clarendonian (late Miocene). The new leptarctine differs from other species in having a rounded trigonid and a well-defined hypocontilid on m1 and an enlarged accessory cusp on p3. Pseudoleptarctus genowaysi has the largest dentition known for leptarctines. The morphological similarities to procyonids indicate their shared aspects of diet.
