The Puebla deer vole ( Peromyscus mekisturus ) is a possibly extinct rodent from the genus of the whitefoot mice ( Peromyscus ) in the family of the burrows (Cricetidae). It was endemic to the Mexican state of Puebla and is only known from two specimens.

features

In the holotype , a female, the head-trunk length is 249 mm, the tail length 155 mm and the hind foot length 24 mm. The second specimen is a male with a head-trunk length of 222 mm, a tail length of 135 mm, a hind foot length of 22 mm and an ear length of 17 mm. The upper side is gray in front, gradually changes to an olive-reddish yellow and is pale reddish yellow on the rump. The back is somewhat covered with black hair, but there is no dark back area. The nose is gray with a small whitish spot on the extreme tip. A dark ring runs around the eyes. The underside is yellow-brown-whitish, the chest region yellow-brown and the chin, lips and sides of the muzzle are whitish. The wrists are dark and the forefeet white. The front of the ankles and the upper two-thirds of the metatarsus are dark. The rest of the hind paws, toes and sides of the ankle are white. The tail is dark on top and indistinctly lighter on the underside. The rostrum of the skull is short and narrow. The cheekbone is square and spreads forward. The outer sides converge strongly towards the front. The frontal bone narrows between the eye sockets. There is no bulge above the eye, as in other Peromyscus species. The skull is wide and fairly flat. The Inca leg is narrow. The tympanic membrane is small.

status

The holotype was collected in March 1894 by Edward William Nelson and Edward Alphonso Goldman at an altitude of 2560 m near Chalchicomula ( Ciudad Serdán ) in the Mexican state of Puebla. The second specimen was caught in 1947 by Emmet Thurman Hooper (1911-1992) at 1700 m altitude near Tehuacán in the state of Puebla. The IUCN lists the Puebla deer vole in the category “critically endangered” with the addition “possibly extinct”. Presumably the area of ​​the distribution area is less than 100 km². The habitat is highly fragmented and acutely affected by agricultural activities.
