The new species can be differentiated from the eight species of Filaria from the Old World by the shape of the sclerotized preesophageal ring. The four remaining species of the genus parasitize American Mephitidae and/or Mustelidae. Filaria carvalhoi from Brazil and F. texensis from USA lack a preesophageal ring, whereas F. taxideae from USA and F. conepati from Argentina share with our specimens a preesophageal ring mostly mushroom shaped. Our specimens differ from F. taxideae by lacking lateral alae, by a different ornamentation of the female tail and by the male lacking adcloacal papillae. The new species also differs from F. conepati by the shape of the preesophageal ring and by the shape of the eggs. The indirect examination of the types of F. conepati and F. carvalhoi, corroborated the existence of differences between these two species, allowing us to refute their synonymy, as proposed by some authors. Our results extend the taxonomy of Filaria to 13 species and comprise the fi rst report of a fi larioid nematode for an Argentinean mustelid, and the fi rst report for Patagonia.

Estos registros incrementan en 135 km lineales hacia el sudeste la extensión geográf ca de esta especie en la Patagonia. Los nuevos registros fueron obtenidos a partir de evidencias directas, indirectas y reportes de pobladores. Asimismo, se discuten brevemente las amenazas para la conservación de los ecosistemas nativos y las actividades productivas que se desarrollan en la zona como consecuencia del ingreso del jabalí.

This represents the first contemporaneous record of H. brasiliensis in Patagonia, and also the only species of sigmodontine rodent with amphibious habits reported in Patagonia.

We added new localities for several of the most uncommon small mammal species of this region (e.g. Loxodontomys micropus and Tympanoctomys barrerae). Two main groups of terrestrial non-volant micromammals are represented in southwestern province of Mendoza: one group is related to the South American arid diagonal, and includes species typically adapted to the xeric environments of the Monte Desert; a second group includes Patagonian and High Andean species. Some Patagonian species reached in the study area their northernmost distributional records (e.g. Abrothrix longipilis, A. olivaceus, Chelemys macronyx, Loxodontomys micropus).

Two exceptions were species of coyote-sized Dusicyon, one insular (D. australis) and one continental (D. avus). The extinction of the former is a resolved matter, but that of D. avus, found in the Patagonian and Pampean regions, is still poorly understood. Using the Gaussian-Resampled Inverse-Weighted McInerny method we present new radiocarbon evidence indicating that its disappearance occurred in very recent times (about 324-496 years cal BP). We found no evidence to support a role for hybridization with domestic dogs in causing the extirpation of this fox. Climatic change may have reduced its distributional range, as has happened with other mammals, although not to the extent of explaining its extinction. Climatic change, however, coupled with increased anthropogenic impacts such as hunting, domestic dogs, and/or other aspects relating to the impact of European colonization in South America's southern cone, were the probable main drivers of the recent extinction of D. avus.
