The genus Lycalopex ( Syn .: Pseudalopex , German  "Andean foxes" ) contains a number of canids, which are called "foxes" and have external similarities with them. However, it belongs to the real dogs tribe , which is compared to the real foxes .

description

Andean foxes reach a head-trunk length of 53 to 120 cm. The tail length is 25 to 50 cm. In the genus Lycalopex culpaeus is the largest and Lycalopex Sechurae the smallest. The coat is usually thick, with a dense undercoat and long outer coat . The upper side is generally agouti (ruddy) gray with yellow-brown, the underside is usually paler. The head, ears and neck are often reddish in color. The tail is long, bushy and colored black at the tip. Andean foxes are similar to small coyotes , but their teeth are more similar to those of the fox than that of the dog: the molars are well developed, the fangs are relatively short.

distribution

Andean foxes are found in Argentina, Bolivia, Brazil, Chile, Ecuador, Paraguay, and Peru. The Darwin Fox, classified by the International Union for Conservation of Nature and Natural Resources as "critically endangered" is an endemic to Chile.

Way of life

They are mostly nocturnal species, but some specimens are occasionally also active during the day. Lycalopex are omnivores . In addition to rodents, birds, lizards, frogs and insects, they eat fruits and sugar cane . The Andean jackal seems to be more carnivorous ; its prey also includes sheep and hares imported from Europe.

As part of the presentation of the genome sequence of the domestic dog , Lindblad-Toh et al. 2005 published a phylogenetic analysis of dogs (Canidae). In the context of this presentation, the Maikong ( Cerdocyon thous ) was identified as a sister species of the genus Lycalopex on the basis of molecular biological data . The short-eared fox ( Atelocynus microtis ), which is also native to South America , was shown as a sister species of this group; other species of the clade are the forest dog ( Speothos venaticus ) and the maned wolf ( Chrysocyon brachyurus ).
