The Van Gelder bat ( Bauerus dubiaquercus ) is a bat in the smooth-nosed family (Vespertilionidae) that occurs in Central America. The species was temporarily listed with the desert bat ( Antrozous pallidus ) in the genus Antrozous . Newer taxonomic works lead them in the monotypical genus Bauerus .
The generic name Bauerus honors Harry J. Bauer, who financed the expedition on which the species was discovered. The species name dubiaquercus is composed of the Latin words dubia (doubtful) and quercus (oak, English oak ) to honor the expedition participants Richard G. Zweifel and Oakes A. Plimpton.
features
With a head-to-trunk length of 57 to 75 mm and a tail length of 46 to 57 mm, the species is about the same size as the desert bat, but it is slightly lighter at 13 to 20 g. The forearm length ranges from 48 to 57 mm. Bauerus dubiaquercus is also similar to the desert bat in other body features . The species has a darker brown colored fur and larger ears. In some individuals, there are additional needle-shaped third incisors in each half of the lower jaw. The tail is completely enclosed by the tail skin. On the well-developed spur of the hind legs ( calcar ) there is an elongated hump.
distribution and habitat
The distribution area extends from southern Mexico to Costa Rica . Bauerus dubiaquercus has several separate populations in this region, the species also occurs on the Mexican Marias Islands . In the mountains it reaches 2300 meters above sea level. Different types of forests serve as habitat .
Way of life
The way of life of this bat is largely unexplored. It probably eats flying insects, which may be completed with parts of plants. One young is born per litter. The species flies at a low altitude above the bottom of forest aisles or clearings. Trapped specimens were successfully fed cockroaches and leaf locusts.
status
Environmental pollution and deforestation threaten the existence of the species. It is listed by the International Union for Conservation of Nature (IUCN) in the early warning list ( Near Threatened ).
