Thomas's big-eared brown bat (Histiotus laephotis) is a species of vesper bat found in South America.
Thomas's big-eared brown bat was described as a new species in 1916 by British zoologist Oldfield Thomas. [2] Thomas described the species based on specimens held by the Turin Museum of Natural History that had been collected by "Dr. Borelli", [2] likely Dr. Alfredo Borelli, who furnished many biological specimens during this time from Argentina, Paraguay, and Bolivia. [3] The holotype had been collected in Caiza, Bolivia, which is located in the Potosí Department of Southern Bolivia. [2] Of the species name "laephotis", Thomas was not clear on its meaning, though he remarked that it "[had] a similar meaning" to the name histiotus, [4] which means "sail ear" (from Ancient Greek "ἱστός" meaning "mast" + "οὖς" meaning "ear"). [5] A hypothesis for the etymology of laephotis is that it comes from Greek "λαιός" meaning "awkward" and "φως" meaning "light," possibly referring to an awkward flight in the daylight. [6]
The validity of Thomas's big-eared brown bat as a species has been disputed. In the past, it has been regarded as a subspecies of the big-eared brown bat, H. macrotis. [7] More recently, it has been considered a subspecies of the small big-eared brown bat, H. montanus. [8] At present, several sources consider it a valid species. [9] [10]
Individuals weight approximately 11 g (0.39 oz). [11] Its ears are very long relative to other members of its genus, at 32–33 mm (1.3–1.3 in) long. The ears are 23–24 mm (0.91–0.94 in) wide. Its fur is dark brown, with the tips of individual hairs lighter brown. Its ears and flight membranes are grayish in color. Its forearm is 46–51 mm (1.8–2.0 in) long. From head to tail, it is 104 mm (4.1 in) long. Its tail is 50 mm (2.0 in); its tragus is 11 mm (0.43 in) long. [2] It can be differentiated from the similar small big-eared brown bat (Histiotus montanus) by its yellowish fur, pale ears, and longer forearm. [11]
Its range includes Peru, Bolivia, and Argentina. [10] In March 2006, it was documented in Brazil for the first time. [12] A paper published in 2015 cited its first ever documentation in Chile. [11]
As of 2019, it was evaluated as near-threatened by the IUCN. [10]
Vespertilionidae is a family of microbats, of the order Chiroptera, flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat families, specialised in many forms to occupy a range of habitats and ecological circumstances, and it is frequently observed or the subject of research. The facial features of the species are often simple, as they mainly rely on vocally emitted echolocation. The tails of the species are enclosed by the lower flight membranes between the legs. Over 300 species are distributed all over the world, on every continent except Antarctica. It owes its name to the genus Vespertilio, which takes its name from a word for bat, vespertilio, derived from the Latin term vesper meaning 'evening'; they are termed "evening bats" and were once referred to as "evening birds".
The mouse-eared bats or myotises are a diverse and widespread genus (Myotis) of bats within the family Vespertilionidae. The noun "myotis" itself is a Neo-Latin construction, from the Greek "muós and "oûs", literally translating to "mouse-eared".
The big-eared woolly bat or (Peters's) woolly false vampire bat is a species of bat, belonging to the family Phyllostomidae.
The tropical big-eared brown bat, is a bat species found in Bolivia, Peru, Argentina, Brazil and Paraguay.
The velvety myotis, is a species of vesper bat from South America.
The cinnamon dog-faced bat, is a South American bat species of the family Molossidae. It is found in northern and central South America.
The white-throated round-eared bat is a bat species found from Honduras to Bolivia, Paraguay and Brazil. It creates roosts inside the nests of the termite, Nasutitermes corniger. It thrives on a mainly insect-based diet, focusing on the surfaces of foliage to hunt, and also eats fruit and pollen. It has a very wide range and is a common species over much of that range, so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Eptesicus is a genus of bats, commonly called house bats or serotine bats, in the family Vespertilionidae. The genus name is likely derived from the Greek words ptetikos 'able to fly' or petomai 'house flier', although this is not certain.
The big-eared brown bat is a species of vesper bat found in Argentina, Paraguay, and Chile.
The small big-eared brown bat is a species of vesper bat in the family Vespertilionidae. It can be found in Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Peru, Uruguay, and Venezuela.
The big-eared pipistrelle is a species of vesper bat in the family Vespertilionidae. It can be found in Indonesia and Malaysia. It forages over mud flats over Peninsula Malaysia but its roosting activities are unknown. Its habitat is being threatened by deforestation for agriculture, plantations, logging and fires but how it affects this bat or if it is adaptable are unknown.
Histiotus is a genus of South American vesper bats with species that include:
The Vespertilioninae are a subfamily of vesper bats from the family Vespertilionidae.
The Patagonian bonneted bat, also called the Patagonian dwarf bonneted bat, is a species of free-tailed bat found in Argentina, Bolivia and Paraguay.
The Isalo serotine is a vesper bat of Madagascar in the genus Laephotis. It is known only from the vicinity of the Isalo National Park in the southwestern part of the island, where it has been caught in riverine habitats. After the first specimen was caught in 1967, it was described as a subspecies of Eptesicus somalicus in 1995. After four more specimens were collected in 2002 and 2003, it was recognized as a separate species. Because of its small distribution and the threat of habitat destruction, it is considered "vulnerable" in the IUCN Red List.
The southern big-eared brown bat is a species of bat from the family Vespertilionidae. Although current taxonomy treats the southern big-eared brown bat as a separate species, it is often treated as a subspecies of the small big-eared brown bat. It lives in the forests of southern Argentina and Chile; though the population of the bat in the southern part of its habitat is low, there are no major concerns to justify anything lower than a Least Concern rating in the IUCN Red List.
Myotis izecksohni is a species of mouse-eared bat that is endemic to Brazil and Argentina.
Eptescini is a tribe of bats in the family Vespertilionidae. This tribe has a cosmopolitan distribution.
The Moche big-eared brown bat is a species of vesper bat in the family Vespertilionidae. It is endemic to coastal Peru. It is notable for its likely depiction in Moche ceramics over a millennium prior to its discovery to Western science in 2012 and scientific description in 2021.
