Winkelmann's mouse (Peromyscus winkelmanni) is a species of rodent in the family Cricetidae found only in Mexico, and is named for John R. Winkelmann, who collected the first specimens. [2]
Rather larger than a house mouse, an adult Winkelmann's mouse measures 24 to 27 cm (9.4 to 10.6 in) in total length, about half of which is the tail, and weighs around 54 g (1.9 oz). The fur is tawny mixed with black over most of the body, becoming darker on the back, sometimes forming a distinct black band in the center of the back, and fading to bright tan or cinnamon on the flanks and cheeks. The under parts are pale grey. The tail has only a thin covering of hair, typically darker on the upper than on the lower surface. [2]
Compared with other, related, species, the ears are relatively small and dark in color, and the skull is slightly larger. However, Winkelmann's mouse can most readily be distinguished from its close relatives by the shape of its penis, which has a partially corrugated glans. [3] Females have six teats. [2]
Winkelmann's mouse is found only in a relatively small area of southern Michoacán in Mexico, where it inhabits isolated regions on the western slopes of the Sierra Madre Occidental. [1] It lives in woodland patches of tall oak trees, mixed with pines. These areas have dense understories, and thick epiphytes, including patches of mosses, orchids, and bromeliads. [2] There are no subspecies. Because it is only found in such a small area, and because much of the woodland on which it depends is currently subject to logging, it is formally considered an endangered species by the IUCN. [1]
Schmidly's deer mouse, is a recently described species of deer mouse from the mountains of western Mexico. It is part of the highly complex and well-studied Peromyscus boylii species complex. The uniqueness of Peromyscus from this area had long been suspected, but was only formalized in 2004 with the publication of its species description. The species was named in honor of David J. Schmidly, a mammalogist and former president of the University of New Mexico.
The Mexican volcano mouse is a species of rodent in the family Cricetidae endemic to high elevation areas of the Trans-Mexican Volcanic Belt.

The Tres Marías island mouse or Tres Marías deer mouse is a species of rodent in the family Cricetidae. It is found only on the Islas Marías off the west coast of Mexico. When last assessed, it was common on María Cleofás Island, but rare or absent on the other, more disturbed, islands.
The Puebla deer mouse is a species of rodent in the family Cricetidae. Only two specimens are known, both from Puebla, Mexico, with the last collected in 1947. It is therefore possible that the species is now extinct, although it is currently listed as Critically Endangered by the IUCN.

The tawny deer mouse or marsh mouse is a species of rodent in the family Cricetidae. It is found only in Mexico.
The false canyon mouse or Coronados deer mouse, is a species of rodent in the family Cricetidae. It is known only from Coronados Island, a small island in the Gulf of California, part of Baja California Sur, Mexico. The species is threatened by predation by feral cats, and the IUCN has assessed its conservation status as "critically endangered".
The Santa Cruz mouse is a species of rodent in the family Cricetidae. It is endemic to Mexico, where it is found only on two small islands in the southern Gulf of California. Feral cats on Santa Cruz Island are a threat.
The Nayarit mouse or Sinaloan deer mouse is a species of cricetid rodent endemic to Mexico. It was considered a subspecies of brush mouse until 1977.
Slevin's mouse, also known as the Catalina deer mouse, is a species of rodent in the family Cricetidae. It is endemic to Isla Santa Catalina off the east coast of Baja California Sur, an island with an area of about 40 km2 (15 sq mi), and it is the only native mammal on the island. It is named for Joseph Slevin, a curator at the California Academy of Sciences.
The narrow-skulled pocket mouse is a species of rodent in the family Heteromyidae. It is endemic to western Mexico, living west of the Sierra Madre Occidental crest.
