A new distributional record for Lyncodon patagonicus Carnivora: Mustelidaeone of the smallest and least known mustelids of South America.

Patagonian weasel

The Patagonian weasel Lyncodon patagonicus is a small, rare, and little lybcodon carnivore. Its distribution, which includes several fossil and historical records, spans western Argentina and southern Chile. According to recent studies, its populations are declining, affecting its conservation. In this paper we report a new locality of occurrence for the species based on a photographed individual from Lihue Calel National Park, La Pampa Province.

The importance of this record is that it is located km southwest from the nearest previously known reference, and helps to fill a wide gap in the center of its range, where there were no previous records. En este trabajo se registra una nueva localidad de presencia para esta especie basada en un individuo fotografiado en el Parque Nacional Lihue Calel, lyncodoj de La Pampa.

Within this wide distribution, most of its records of occurrence in the Pampas, Espinal, and Low Monte ecoregions of central Argentina correspond to historical or fossil records Prevosti et al. A recent work has modeled the past and extant potential distribution of the Patagonian weasel and found that this species is experiencing a retraction in its area of occurrence, an issue that will affect the conservation of this rare mustelid Schiaffini et al.

The aim of this work is to report a new locality for this species. The new locality fills a large gap in its geographic distribution and represents the third record for La Pampa Province Argentina. On July 11tha specimen of L. The climate in this park is semiarid, characterized by summers with mean temperature of Collecting year Prevosti et al. Terrestial ecoregions are colored as follows from north-east to south-west: The lesser grison, Galictis cujais similar to L.

Although available information indicates that L. Photos by Dolsan Marcelo. These categories were primarily based on the scarcity of data, and the lack of published information on its geographic distribution, ecology, and main threats. The photograph was taken in Salitral Levalle, which is a typical salt-flat environment, where the vegetation is a halophyte shrubland with dominance of Allenrolfea vaginataAtriplex undulataand Cyclolepis genistoide.

Lyncodon patagonicus occurs in herbaceous and shrub steppes and xerophytic woodlands, including salt flats such as those of the LCNP Prevosti et al. Potential distributional models based on recent i.

Within this context, our record is not included in the current potential models generated by Schiaffini et al. At least in part, this situation is the result of the low number of recent records i. With the evidence at hand we cannot hypothesize if this situation reflects the absence of fieldwork by scientists pataglnicus these areas, if it is the result of naturally low densities of this species in these ecoregions, or both see Prevosti et al.

In contrast, potential distributional models based on Pleistocene and Holocene records made by Schiaffini et al. Patagohicus the possibility that some populations in these ecoregions were relicts of a past, broad distribution, cannot be discarded.
