The Guadeloupe big brown bat (Eptesicus guadeloupensis) is a species of vesper bat. It is found only on the island of Guadeloupe. It is one of the eleven species of bat found on Guadeloupe, and one of three that are endemic. [2]
It was described by Genoways and Baker in 1975. The holotype used for the species description was collected in July 1974 by the authors in eastern Baie-Mahault of Guadeloupe. They believed that it was most closely related to the big brown bat, Eptesicus fuscus. They placed it in the fuscus group of the genus Eptesicus, as defined by Davis in 1966. [3] Before the description of the Guadeloupe big brown bat, the only other member of the fuscus group was its identifier, Eptesicus fuscus: the big brown bat. [4] Its species name guadeloupensis is a Latinized version of Guadeloupe, where the bat is found.
It is the largest member of its genus that occurs in the New World. Its wing membranes are black in color. Its fur is bicolored, with individual hairs black at the base and lighter at the tip. The hairs are chocolate brown at the tip on its back, and [[buff colour)|buffy]] at the tip on its belly. From snout to tail, it is 129–133 mm (5.1–5.2 in) long. Its forearm is 49.6–51.5 mm (1.95–2.03 in) long. Ears are 22.5–24 mm (0.89–0.94 in) long, tail is 54–60 mm (2.1–2.4 in) long, and hind foot is 11–14 mm (0.43–0.55 in) long. [3]
Like all other members of its genus, it is diploid with 50 chromosomes and a Fundamental number of 48. [3] It is insectivorous. During the day, it is thought to roost in trees within gallery forests. [1] It is infrequently encountered, therefore little is known about its reproduction. A post-lactating female and a juvenile female were once encountered in late July, suggesting that females could give birth in May or June. [2]
It is endemic to the Basse-Terre Island of Guadeloupe, which is in the Lesser Antilles of the Caribbean. It is encountered in tropical rainforests and gallery forests. It is most often found at low elevations, from 0–300 m (0–984 ft) above sea level. [1]
It is currently listed as endangered by the IUCN. Major threats to this species include habitat loss, hurricanes, and the spread of exotic, invasive species such as rats, mice, and mongooses. It may also be threatened by competition with the native velvety free-tailed bat, which is abundant. [1]
The big brown bat is a species of vesper bat distributed widely throughout North America, the Caribbean, and the northern portion of South America. It was first described as a species in 1796. Compared to other microbats, the big brown bat is relatively large, weighing 15–26 g (0.53–0.92 oz) and possessing a wingspan of 32.5–35 cm (12.8–13.8 in).

Genoways's yellow bat is a species of vesper bat found only in Mexico. It is threatened by habitat loss. Due to its imperiled status, it is identified by the Alliance for Zero Extinction as a species in danger of imminent extinction.
The inland forest bat is a vesper bat that occurs in central and arid regions in Australia. They were first described in 1987, published in a review of poorly surveyed microbat populations. A tiny flying mammal, it occupies small cavities in trees and buildings while roosting. The nocturnal activity is foraging for insects, typically moths.
Finlayson's cave bat is a species of vesper bat found only in Australia.
The Guadeloupe big-eyed bat is a species of bat in the family Phyllostomidae. It is found in Guadeloupe and Montserrat. It is threatened by habitat loss mostly because of Hurricane Hugo, which destroyed 90% of its population in 1989. The species may be locally extinct in some areas of Guadeloupe.
The Kolar leaf-nosed bat, or leafletted leaf-nosed bat is a species of bat in the family Hipposideridae. It is endemic to India. Its natural habitats are subtropical or tropical dry forests and caves. It is found in only one cave in India, and its population is less than 200 individuals.
