Mexican volcano mouse
|Mexican volcano mouse
Temporal range: Pleistocene – Recent
Taxonomy and systematics
Merriam originally described the Mexican volcano mouse as one of three species in the genus Neotomodon; N. alstoni was moved to the deer mouse genus Peromyscus in 1979, then subsequently moved back to Neotomodon. Merriam does not state after whom the species is named in his original description for the genus (and species). Despite the current taxonomy, a recent phylogeny based on cytochrome-b sequences shows Peromyscus to be polyphyletic, and the authors of that paper suggest Neotomodon (and several other monotypic genera) be transferred to Peromyscus.
With relatively large eyes and ears, bi-colored body and tail (dark dorsally and white ventrally), and a tail slightly shorter than the body length, the Mexican volcano mouse appears very similar to a deer mouse, but it is diagnosed by several skull characters including the number and extent of palatal ridges and molar characteristics.
Mexican volcano mouse breeding is thought to occur between June and September, with two to three litters per year of 3.3 young per litter. The mouse exhibits bi-parental care in captivity, which suggests a monogamous mating system. Little is known about other life history characteristics of the species, for example, sex ratio, age at first breeding, etc.
