Genoways's Yellow Bat
Genoways's yellow bat (''Rhogeessa genowaysi'') 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. Taxonomy and etymology This species was described in 1984 by Robert J. Baker, based on an individual that was collected in 1981. The eponym for this species is Hugh H. Genoways, whom Baker chose "in recognition of his outstanding contributions to systematic mammalogy." It is one of the seven species recognized in the black-winged little yellow bat species complex.Genoways, H. H., & Baker, R. J. (1996). A new species of the genus ''Rhogeessa'', with comments on geographic distribution and speciation in the genus. Its closest relative is the black-winged little yellow bat.

Thomas's Yellow Bat
Thomas's yellow bat (''Rhogeessa io'') is a species of bat from the family Vespertilionidae. Taxonomy Thomas's yellow bat was given its binomial nomenclature by Oldfield Thomas in 1903 as ''Rhogeessa io''. Synonyms for the species include ''Rhogeessa bombyx'' (Thomas, 1913), ''Rhogeessa riparia'' (Goodwin, 1958), and '' Rhogeessa velilla'' (Thomas, 1903). The Thomas's yellow bat was formerly included as a subspecies of the black-winged little yellow bat, but was considered distinct in 1996. The species needs taxonomic review for a number of reasons. One of these reasons includes the possibility that subspecies of the Thomas's yellow bat may be their own species. Range and conservation Thomas's yellow bat is native to Bolivia, Brazil, Colombia, Costa Rica, Ecuador, French Guiana, Guyana, Nicaragua, Panama, Suriname, Trinidad and Tobago, and Venezuela. It is listed as "Least Concern" by the IUCN Red List due to its wide distribution, presumed large population, occurrence in a n ...

Ecuadorian Little Yellow Bat
''Rhogeessa velilla'', also called the Ecuadorian little yellow bat, is a species of vesper bat in the genus ''Rhogeessa''. It is found in Northwestern Peru and parts of Ecuador. The species was previously included in '' R. io'', but is now recognized as a separate species. Very little is known about this species, though it is generally considered to be insectivorous. Taxonomy ''Rhogeessa velilla'' was described as a new species in 1903 by British zoologist Oldfield Thomas. The holotype was collected by Perry O. Simons on Puná Island in 1898. In 1958, George Gilbert Goodwin published that he considered it a subspecies of the little yellow bat (''R. parvula''). In 1973, R. K. LaVal published that it should instead be considered a subspecies of the black-winged little yellow bat (''R. tumida''). In 1996, Hugh H. Genoways and Robert James Baker elevated Thomas's yellow bat (''R. io'') from a subspecies of the black-winged little yellow bat; ''R. velilla'' was then considered synon ...

Husson's Yellow Bat
Husson's yellow bat (''Rhogeessa (Rhogeessa) hussoni'') is a species of vesper bat found in Suriname and southern Brazil. Description Husson's yellow bat is primarily distinguished from other species in the genus ''Rhogeessa'' (particularly from '' R. io'' which is also found in Brazil) by its fur colour. Both its ventral and dorsal fur is golden brown with brown tips. Its muzzle is similar to that found in the genus ''Eptesicus'' with more obvious pads than ''R. io''. Cranial measurements including breadth of the upper canines and palate, and the length of the teeth across the maxillary bone were all larger in Husson's yellow bat. Conservation status There have been difficulties capturing vesper bats using the usual methods and problems differentiating the different species within the genus ''Rhogeessa''. As a results of this, very little is known about the species and the IUCN The International Union for Conservation of Nature (IUCN; officially International Union ...

Yucatan Yellow Bat
The Yucatan yellow bat (''Rhogeessa aeneus'') is a species of bat found in the Yucatán Peninsula in Mexico, and possibly also in Belize and Guatemala.

Range and habitat A small population of these bats has been observed on Spanish Lookout Caye, Belize, since at least 1998. They are on both the east and west sides of the mangrove caye, which is located east of Belize City in the Drowned Cayes Range. According to the locals who work on the caye, the bats are thought to roost in the coconut trees ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Yellow Bat
The little yellow bat (''Rhogeessa parvula'') is a species of vesper bat found only in Mexico. Description One of the smallest vesper bats, adult little yellow bats measure only in total length, with a forearm about long, and weigh just . There may be some cline (biology), clinal variation in body size, with the smallest individuals being found in the Nayarit region, and size increasing both to the north and south of this area. As the common name suggests, the fur is generally yellowish, with individual hairs being a fawn or chestnut brown for most of their length, and greyish brown at the base. The fur is silky in texture, and fades to a greyer shade on the animal's underside. The wing membranes are black and hairless, except for a small patch of fur on the membrane between the legs. The tail extends to the end of the uropatagium. The head is unusually small and narrow, with whiskers, small pointed ears, and tiny eyes. There is a wart above each eye, and another below the chi ...

Black-winged Little Yellow Bat
The black-winged little yellow bat (''Rhogeessa tumida'') is a species of Vespertilionidae, vesper bat native to Central America. Description The black-winged little yellow bat is a small bat, with a total length of between , and no significant difference in size between the sexes. The fur is buff or yellowish, ticked with near-black or cinnamon, and is paler on the bat's underside. The flight membranes are hairless, and unusually thick for a bat of its size. The ears are smaller than in many closely related species, and have a prominent scent gland on their upper surface in males that is absent in females. Biology Little is known of the habits of biology of the species. Individuals have commonly been caught near streams or rivers, and roost in hollow trees or artificial structures. They are nocturnal, being most active shortly after sunset and just before dawn, and feed on small, flying insects. They have diploid chromosome numbers of 30, 32, 34, and 52.

Allen's Yellow Bat
Allen's yellow bat (''Rhogeessa alleni'') is a species of vesper bat. There is some taxonomic debate surrounding this species, with some authors considering ''Baeodon'' a genus rather than a subgenus. It is endemic to Mexico. Taxonomy and etymology It was described as a new species in 1892 by British zoologist Oldfield Thomas. Thomas noted that the eponym for the species name "''alleni''" was Harrison Allen, calling him "the chief authority on North-American bats." In 1906, Gerrit Smith Miller Jr. placed Allen's yellow bat into a newly-coined genus, ''Baeodon''. At present, some authors keep Allen's yellow bat as part of ''Rhogeessa'' within the subgenus ''Baeodon'', while others believe that it is distinct enough that ''Baeodon'' should be considered a monotypic genus rather than a subgenus. Description It is a small species of bat, weighing only . It has large ears, with long tragi. The tragi are rounded at the tips, with a straight or slightly concave inner margin and a sl ...

Menchu's Little Yellow Bat
Menchu's little yellow bat (''Rhogeessa menchuae'') is a species of vesper bat found in Central America. It was described as a new species in 2012. Taxonomy and etymology Menchu's little yellow bat was described as a new species in 2012 by Baird et al. Morphological and genetic analyses differentiated it from the black-winged little yellow bat, ''R. tumida''. The holotype was collected by R. D. Bradley in 1991 in the Atlántida Department of Honduras. The eponym for the species name "''menchuae''" is Rigoberta Menchú.
