In this article we describe a new species of Pseudoloris (Omomyidae, Primates) from the Robiaclan (middle Eocene) locality of Sant Jaume de Frontanya (Eastern Pyrenees, Spain). Pseudoloris pyrenaicus is characterized by its medium size, thickened paracristid, absence of a distinct paraconid, and well-developed buccal cingulid in the lower molars, large hypoconulid in the M(3), paraconule and hypocone reduced in the M(1) and M(2) and absent in the M(3). The material from Sant Jaume de Frontanya constitutes the most abundant sample of the genus Pseudoloris found until now in the Iberian Peninsula. Almost all the dental elements have been recovered, including those teeth hardly known for other species of the genus, such as lower and upper incisors. The new species shows intermediate features between Pseudoloris isabenae from Capella and Pseudoloris parvulus, present in different Spanish and French sites. Therefore, we consider that Pseudoloris pyrenaicus is an intermediate form between these two species. Am J Phys Anthropol 143:92-99, 2010.
