Van Gelder's bat


Van Gelder's bat is a species of vesper bat in the family Vespertilionidae.
It is found in Belize, Costa Rica, Honduras, and Mexico. The species is monotypic within its genus. It is part of the tribe Antrozoini within the subfamily Vespertilioninae and is related to the pallid bat. The bat is found in forest habitat from sea level to elevations as high as 2300 m, although not usually above 1300 m, and is insectivorous and crepuscular. It apparently has a fragmented distribution, and is threatened by deforestation.

Taxonomy and etymology

The bat was discovered by Richard Van Gelder, then curator of mammalogy at the American Museum of Natural History. The bat was collected on the AMNH Puritan Expedition to Baja California in 1957 on the Tres Maria Islands by Richard Zweifel and Oakes Plimpton. Van Gelder dubbed the bat "dubiaquercus" in honor of the collectors: dubia means "doubt" in Latin, as zweifel does in German; quercus is Latin for "oak".

Range and habitat

Van Gelder's bat is found in Central America where its range includes Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua.
It has been documented at a range of elevations from above sea level.

Conservation

As of 2018, it is evaluated as a near-threatened species by the IUCN.
It meets the criteria for this classification because it is locally uncommon throughout its range; it is experiencing significant population declines; and its habitats are "highly fragile".
