Asháninka arboreal chinchilla rat

The Asháninka arboreal chinchilla rat[1] (Cuscomys ashaninka) is a large species of chinchilla rats from the Andes of far northern Cusco in Peru. It was first scientifically described in 1999.

Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Rodentia
Family: Abrocomidae
Genus: Cuscomys
Species:
C. ashaninka[2]
Binomial name

Emmons, 1999

The first specimen of this species was discovered by Dr. Louise Emmons, a researcher of the Smithsonian Institution from Washington, D.C., who found it by chance while climbing in the Vilcabamba Mountains near Machu Picchu. Emmons named the genus after the city of Cusco, and she named the species for the Asháninka people who live in Peru.[3]

Description and habitat

The animal has grey fur, with a white nose and lips, large claws, and a line of white fur running down its head.[3] It is 30 cm (12 in) in length, with a tail of 20 cm (7.9 in). It weighs 910 g (32 oz).[4] Ashaninka arboreal chinchilla rats live in dwarf forest and are hunted by long-tailed weasels.[1]

Classification

When described, it was placed in the family Abrocomidae, but was considered different enough from existing species for the creation of the genus Cuscomys. Since then, the Machu Picchu arboreal chinchilla rat (Cuscomys oblativus), a species of chinchilla rats originally placed in the genus Abrocoma, has been shown to be a member of Cuscomys. Although it was considered extinct by the IUCN at the time, photos of a rodent showing some similarities to C. ashaninka taken at Machu Picchu in late 2009 may show C. oblativus.[5]
