It was synonymized subjectively with Vulpes by Gregory (1942); it was revalidated by Webb (1969), Carroll (1988), and Munthe (1998). It was assigned to the Canidae by Matthew (1918), Webb (1969), Carroll (1988), and Munthe (1998).[4][5]MorphologyBody massTwo specimens were examined by Legendre and Roth.
