The European adapid primates Agerina and Pronycticebus. American Museum novitates ; no. 2466

Abstract

"The entire sample of Agerina roselli Crusafont-Pairo, 1967, from late early Eocene sediments of the Ager Basin, Spain, is described and compared with its nearest relatives, species of Protoadapis, Pelycodus, and Pronycticebus gaudryi. Agerina is not a necrolemurid as suggested by its describer, but is clearly a member of the Adapidae. Two additional genera, described by Crusafont-Pairo in 1967 as omomyids, Arisella and Pivetonia, bear no particular resemblance to that group. The type specimen of Arisella appears to be an adapid, possibly that of Agerina or Protoadapis, whereas the sample described as Pivetonia isabenae may be near Pseudoloris parvulus. Generic distinction from Pseudoloris is not warranted, although Pseudoloris isabenae may be specifically distinct from Pseudoloris parvulus. A reevaluation of the cranium of Pronycticebus gaudryi confirms the view that this taxon is a primitive adapid"--P. [1].
