The hair-footed mouse- eared bat ( Myotis keaysi ) is a bat belonging to the genus mouse- eared bat that is widespread in Latin America .
Appearance
This species is a small bat with a woolly fur. The length of the body of the head varies between 4.1 and 5.3 cm, plus a 3.3 to 4.1 cm tail. The color of the fur varies and can be gray, brown or reddish brown.
The hair-footed mouse- ear is very similar to other South American mouse-ears like the black mouse-ear ( Myotis nigricans ), the decorated mouse-ear ( Myotis elegans ) and the mountain mouse-ear ( Myotis oxyotus ) and is difficult to distinguish from them. These types can be distinguished from one another on the basis of features of the skull, the hair of the uropatagium and the shape of the penis bone .
distribution
The northern limit of the range is in Tamaulipas ( Mexico ). From here the hair-footed mouse-eared mouse is spread over all of Central America and in western South America ( Colombia , Venezuela , Peru , Ecuador , Bolivia , Argentina ). It is also found on the island of Trinidad .
Both rain and dry forests and arid scrubland are accepted as habitats. Limestone caves and tree caves are sleeping places, but today also bridges and house roofs.
Systematics
The hair-footed mouse-eared mouse-ear was originally considered a subspecies of the red mouse-eared mouse ( Myotis ruber ), then the black mouse-eared ( Myotis nigricans ). In 1973, LaVal classified them as a distinct species.
There are two subspecies:
- Myotis keaysi keaysi , in western South America
- Myotis keaysi pilosatibialis , in Central America, in northern South America and in Trinidad
