Population [top]

Population: This bat is rare; apparently know only from two localities (Ceballos and Oliva, 2005). They are very difficult to distinguish from sibling wide spread species Rhogeessa tumida and because of that it could have been missidentified (Arroyo-Cabrales pers. comm.)
Current Population Trend: Decreasing
Additional data:
Population severely fragmented: Yes

Habitat and Ecology [top]

Habitat and Ecology: This species has been taken under the canopy of mature second growth lowland tropical forest. It is an aerial insectivore and is among the first bats to appear in the evening for feeding. No information about its reproduction is available. However, closely related species such as Rhogeessa tumida is known to bear two young per year with individuals reaching sexual maturity at the age of one year (Roots and Baker, 1998).
Systems: Terrestrial

Threats [top]

Major Threat(s): The area is very affected by tropical storms in some cases even hurricanes (Arroyo-Cabrales and Jimenez pers. comm.) and habitat loss due to conversion to agriculture.

Conservation Actions [top]

Conservation Actions: It is found only in a very restricted State protected area. The species is including inside the Mexican regulation for species conservation NOM-59-SEMARNAT-2001 (under P categorie which means Endangered of extinction).
