Range

Endemic to Mexico, it is found in the mountains from southern Hildalgo south through Puebla and Veracruz to the volcanic edifices of Cofre de Perote and Pico de Orizaba,[1] the former being the type locality.[2]

Description

This rodent is light to dark brown in color and weighs 400 to 650 g, with males being slightly larger. There are usually small white areas near the base of the tail.[5] Its karyotype has 2n = 38 and FN = 72.[4]

Habitat

It inhabits Zacatonal grassland and temperate pine-oak woodlands at elevations from 2400 to 4000 m.[1]

Taxonomic history

Initially described as a species in 1895,[2] C. perotensis was demoted to a subspecies of C. merriami in 1968.[6][7] In 2005 it was split off again when found to be distinct in molecular, chromosomal and morphological characters.[4] It subsumes the previously proposed taxa C. estor (Merriam, 1895), C. merriami irolonis (Nelson and Goldman, 1934), C. irolonis (Davis, 1944), and C. merriami peraltus (Goldman, 1937), and is part of the C. castanops species group.[4]

Conservation status

Although it occupies an area of less than 20,000 km2, C. perotensis is thought to be common and is not considered threatened.[1]
