    Physical description
    The coat is short with a pale grey colouration on the upper body and yellowish-gray underparts, however pelage colours vary across its range. The ears and paws are slightly reddish. The tail has long hair. Is similar in appearance to the Crab-eating fox (Cerdocyon thous), which occurs in the same areas.

    Habitat and Ecology
    This species is only found in Brazil, and occurs in the region of the central Brazilian plateau, occupying open grassland areas of Cerrado and presenting predominantly nocturnal activity patterns (Dalponte 2009).
    The diet includes mainly includes insects (termites, ants, dung-beetles), and also small rodents, birds and fruits (Courtenay et al. 2006; Dalponte 1997; Ferreira-Silva & Lima 2006). During times of high food availability (e.g. termite swarms) they can be seen in groups of 3-5 individuals
    The pups are born in abandoned burrows of armadillos or in dense vegetation.

    Threats and Conservation
    There is no data available on current population densities or abundances. Initial findings suggest that their dietary flexibility and tolerance of agricultural plantations means that habitat loss is not a major threat to this species. However impacts of urban expansion and disease transmission from domestic animals remain unknown.
