Lyncodon

Lyncodon is a genus of mustelid containing a single species, the Patagonian weasel (Lyncodon patagonicus), first described in 1842 and found in the Pampas of western Argentina and parts of Chile. It is a small weasel measuring 300 to 350 millimeters in head and body length with a notably short tail of 60 to 90 millimeters, small ears, short legs, and a bushy tail, and its fur is whitish interspersed with black and dark brown tones. Its behavior remains poorly documented due to limited study in the wild, though local ranchers have historically kept it as a working pet to control rodents. The IUCN lists the Patagonian weasel as least concern, indicating a currently stable population.
