About the Arizona Myotis
The Arizona myotis (Myotis occultus) or southwestern little brown myotis is a vesper bat species inhabiting much of the southwestern United States and central Mexico as far south as the Distrito Federal. It was described as a new species in 1909 by American zoologist Ned Hollister.
The holotype was collected near Needles, California, in 1905. Its specific name "occultus" is Latin for "hidden or concealed". It is a small species with a total length of 96 mm (3.8 in)— of the total length, 40 mm (1.6 in) consists of its tail. Its fur is glossy brown with a cinnamon tint. The ventral fur and its face are paler brown. Its range includes parts of the Southwestern United States and the Mexican state of Chihuahua. It is found in a range of elevations from near sea level to 2,806 m (9,206 ft) above sea level.
As of 2018, it is evaluated as a least-concern species by the IUCN. It meets the criteria for this classification because it has a wide geographic range, its range includes protected areas, and it is not likely experiencing rapid population decline. Wikipedia →
