Abstract:

A new genus of echimyid rodent, †Ullumys, from the uppermost Miocene of northwestern Argentina is described. It includes two species, †U. pattoni, sp. nov., and †Ullumys intermedius, nov. comb. †Ullumys pattoni is known from a skull fragment and the corresponding right hemimandible coming from levels of Loma de Las Tapias Formation, underlying a tuff dated at 7.0 ± 0.9 Ma (Huayquerian age, San Juan Province). †Ullumys intermedius is represented by a left hemimandible from the ‘Araucanense’ of Valle de Santa María (Huayquerian age, Catamarca Province). A phylogenetic analysis in the context of octodontoids linked †Ullumys to the clade subtended by the extinct echimyids †Pampamys and †Eumysops and the living Thrichomys. †Ullumys has a peculiar craniomandibular morphology, shared only with †Eumysops among the Octodontoidea, involving specializations to open environments such as large and posteriorly extended orbits and related low mandibular condyles. Phylogenetic relationships of †Ullumys support the hypothesis that echimyids recorded since the latest Miocene in southern South America, and linked to those currently inhabiting Brazilian open biomes, represent a marginal sample of the great diversity evolving primarily in northern tropical areas. http://zoobank.org/urn:lsid:zoobank.org:pub:126592D1-0932-4374- AAD9-97FB59637DA7 SUPPLEMENTAL DATA—Supplemental materials are available for this article for free at www.tandfonline.com/UJVP Citation for this article: Olivares, A.
