000168353 5203_ $$aWe present a detailed description of the craniodental and postcranial remains of the enigmatic Magerictis imperialensis, a basal Ailuridae previously known only from a single m2 from the Middle Miocene of the Madrid Basin (Spain). The discovery of new specimens from eight Middle Miocene (MN5–MN6) localities in Madrid has yielded comprehensive information on the dentition, mandibular morphology, and postcranial skeleton of this species. These new fossils provide an excellent opportunity to revise the phylogenetic relationships of Magerictis and related musteloids from the Oligocene and Miocene of Eurasia and North America. Our phylogenetic analysis indicates that Magerictis and Rothictis gen. nov. are the most basal members of the Aiuluridae. Both genera, together with Alopecocyon, Actiocyon, and Protursus, underwent a limited adaptive radiation during the Middle and Late Miocene in Eurasia and North America. This radiation potentially includes the ancestors of the most specialized ailurids (Simocyon, and the ailurines Parailurus, Pristinailurus and Ailurus). The postcranial elements attributed to Magerictis, particularly the astragalus and calcaneus, exhibit a morphological pattern comparable to that of Ailurus, thereby distinguishing it from other Musteloidea. A systematic rearrangement of the primitive Holartic musteloids from the Oligocene and Miocene is proposed. The Ailuridae are divided into three subfamilies: (i) Ailurinae for Ailurus, Parailurus and Pristinailurus; (ii) Simocyoninae, which includes Simocyon, Protursus, Alopecocyon and Actiocyon; and (iii) Magerictinae nov. rank for Magerictis and Rothictis gen. nov. (type species Rothictis wintershofensis comb. nov.). The family Amphictidae Winge, Citation1895 is revalidated for Amphictis and Bonisictis gen. nov. (type species Bonisictis ambiguus comb. nov.).
