title: Nievesia sossisensis, a new anchomomyin (Adapiformes, Primates) from the early Late Eocene of the southern Pyrenees (Catalonia, Spain).
abstract: A new genus and species attributed to the tribe Anchomomyini is described from the early Late Eocene locality of Sossís (MP17a), one of the most important Paleogene fossil sites from the Iberian Peninsula. Nievesia sossisensis is characterized by its buccolingually compressed P(4) and its upper molars with no pericone, medium-sized hypocone, straight postcingulum and minuscule mesostyle, and the extremely reduced metacone on the M(3). Its lower dentition presents a P4 with an incipient metaconid, lower molars with no paraconid and a premetacristid closing the trigonid basin, and M3 with the trigonid wider than the talonid. Phylogenetic analyses suggest a close relationship between Nievesia and Mazateronodon, although the new genus is also related to Anchomomys and, to a lesser extent, Buxella and Periconodon. These analyses, which also include djebelemurines, no longer relate European anchomomyins with crown strepsirhines, and suggest their closer relationship with asiadapines and sivaladapids.
