Hair- nosed bats ( Mimon ) are a genus in the leaf-nosed family , with four species found in Central and South America .
Types and distribution
The following species belong to the genus.
- The distribution area of the southern hair-nosed bat ( Mimon bennettii ) extends from eastern Colombia to southern Brazil . The species is absent in the central Amazon .
- The Cozumel hair-nosed bat ( Mimon cozumelae ) is found mainly in eastern Central America. It can be found from southern Mexico to Colombia.
- The striped hair-nosed bat ( Mimon crenulatum ) inhabits Central and South America from southern Mexico to Peru , Bolivia and Brazil.
- The Koepcke hair-nosed bat ( Mimon koepckeae ) is restricted to a small area in the highlands of Peru.
The first two species were grouped into one species for a long time. Furthermore, various zoologists were of the opinion that the Koepcke hair-nosed bat is a subspecies of the striped hair-nosed bat.
features
Most of the specimens examined had a head-trunk length of 50 to 75 mm, a tail length of 10 to 30 mm and a forearm length of 48 to 57 mm.
The weight of the southern hair-nosed bat and the Cozumel hair-nosed bat is around 22 g, while the striped hair-nosed bat is significantly lighter at around 12 g. The fur of these bats is usually chocolate brown, black brown or light brown in color. Shades of yellow, orange, or red may appear in older individuals. With a few exceptions, hair-nosed bats have a white, yellow, or orange patch behind their ears. The light eel line that gives the striped hair-nosed bat its name is not found in all specimens.
Like other representatives of the subfamily lance nose , the species have a long, pointed nose sheet . The clear difference between them and other lance noses is the tooth formula with only one incisor and two premolars in the lower jaw.
The German common name of the genus is only applicable to the striped hair-nosed bat and the Koepcke hair-nosed bat. In these, the edges of the nasal blade are wavy and covered with straight hair. In the other two species, the nasal blade has smooth edges.
Way of life
These bats can be found in moist evergreen forests as well as in more dry, deciduous deciduous forests . The two species that occur in Brazil can also be found in the Cerrado savannah landscape . The species differ in further aspects of the way of life.
