Head-body 55-62 mm, tail 33-49 mm, ear 12-18 mm, hindfoot 8-12 mm, forearm 39-48 mm; weight 8-18 g. Females are larger than males. Dorsal hairs of the Brazilian Serotine are relatively long (c. 8 mm ) and bicolored, with dark brown bases and reddish to yellowish-brown tips; ventral hairs have dark brown bases and yellowish to whitish tips. Faceis pinkish and almost hairless, with only sparse hairs near nose. Ears are short, elongated, and triangular, with rounded tips. Tragus is relatively short and broad. Membranes are blackish. Skull is robust; sagittal and lambdoidal crests are well developed; nasal opening is U-shaped; and zygomatic arches have robust postorbital process on medial part ofjugal. Upper inner incisors are separated, bilobed, and spatulated; I’ is reduced, conical, and separated from C' by small gap; P* is well developed, reaching one-third of C'; M' and M* are almost square, with W-pattern; M? is reduced and triangular; lower incisors are trilobed and in contact,filling all space between canines; and lower molars have well-developed cusps, decreasing in size from M, to M,. Chromosomal complement has 2n = 50 and FN = 48, with acrocentric autosomes and Y-chromosome and submetacentric X-chromosome.	Wide variety of habitats from open areas to rainforests in montane forests, lowland forests, gallery forests, temperate forests, savannas, swamps, open areas, orchards, and plantations from sea level up to elevations of ¢. 3000 m .	Brazilian Serotines are insectivorous. Foraging individuals have been caught from ground level up to heights of 30 m . They frequently forage over streams and near water and on edge habitats,trails, clearings, and around lampposts; some individuals seem to establish circular hunting routes. Fecal samples contained fragments of Coleoptera , Lepidoptera , and unidentified insects.	In Brazil , pregnant Brazilian Serotines were caught in September—February, each carrying 1-4 embryos. Lactating females were captured in November—January in Peru and Brazil . Non-flying young were caught in June in Peru . Reproductive cycle shows polyestry, with two pregnancies/year that each last ¢.90 days. Estimated reproductive season in south-eastern Brazil is from mid-Septemberto late February.	Brazilian Serotines are crepuscular and nocturnal. Individuals were caught from shortly before sunset to dawn. Most activity occurs within the first hour after sunset, but second small peak of activity occurs a couple of hours before dawn. Roosts have been found in hollow trees, under loose bark, and in caves, buildings, and dead trees standing in lagoons. Echolocation calls have FM and QCF components that sweep down from 45-75 kHz to 25-36 kHz. Calls have durations of 2-7-10 milliseconds, interpulse intervals of 74-101 milliseconds, and frequencies of maximum energy of 35-49-6 kHz.	The Brazilian Serotine is commonly found in small colonies with up to 14 individuals. It has been found roosting with Pallas’s Mastiff Bat (Molossus molossus) and Common Black Myotis ( Myotis nigricans ).	Classified as Least Concern on The IUCN Red List. The Brazilian Serotine is widespread, with presumably large populations, and occurs in protected areas. It is a locally common species in most ofits distribution.	Arias-Aguilar et al.

Non-flying young were caught in June in Peru . Reproductive cycle shows polyestry, with two pregnancies/year that each last ¢.90 days. Estimated reproductive season in south-eastern Brazil is from mid-Septemberto late February. Activity patterns. Brazilian Serotines are crepuscular and nocturnal. Individuals were caught from shortly before sunset to dawn. Most activity occurs within the first hour after sunset, but second small peak of activity occurs a couple of hours before dawn. Roosts have been found in hollow trees, under loose bark, and in caves, buildings, and dead trees standing in lagoons. Echolocation calls have FM and QCF components that sweep down from 45-75 kHz to 25-36 kHz. Calls have durations of 2-7-10 milliseconds, interpulse intervals of 74-101 milliseconds, and frequencies of maximum energy of 35-49-6 kHz. Movements, Home range and Social organization. The Brazilian Serotine is commonly found in small colonies with up to 14 individuals. It has been found roosting with Pallas’s Mastiff Bat (Molossus molossus) and Common Black Myotis ( Myotis nigricans ). Status and Conservation. Classified as Least Concern on The IUCN Red List. The Brazilian Serotine is widespread, with presumably large populations, and occurs in protected areas. It is a locally common species in most ofits distribution. Bibliography. Arias-Aguilar et al.

The species is usually found in moist habitats, including montane ;and lowland forests, gallery forests, open areas, orchards and plantations. ;It is an aerial insectivore species, that roosts in houses and hollow trees (Emmons and Feer 1997). Active comparatively earlier than other bats; individuals might be seen foraging around lights, and patrolling a circular path (Reid 2009).	Because this species has no specific habitat requirements, no threats can be identified throughout its extense geographic range.	Fairly locally common throughout most of its geographic range, but it may be uncommon on some marginal localities at the north (Mexico) or south (Argentina). Similar to other tropical insectivores, large colonies are not known.	Unknown	E. brasiliensis occurs from Nayarit and Veracruz to the south of South America. In Mexico, it occupies middle elevations of the Sierra Madre Occidental, Sierra Madre Oriental, and Chiapas (Ceballos 2014). ;It does not occurs in western Mexico (Arroyo-Cabralles pers. comm.). ;In South America is found on Trinidad and Tobago, and in Colombia, Venezuela, Guyana, and Surinam south through Ecuador, Peru, Brazil, and Paraguay into Uruguay and northern Argentina (Simmons 2005, Gardner 2008). ;Subgenus ;Eptesicus ; does not include ;andinus , ;chiriquinus , ;inca , or ;montosus ; see Davis (1966) and Simmons and Voss (1998). ;At least four subspecies are currently recognized (Simmons 2005). ;May be a species complex (R. Barquez pers. comm.).		Terrestrial	Same as other Neotropical insectivores with large geographic distributions, this species needs a thoroughly taxonomic review. Through its range, it is found at several protected areas. ;Large variation is expected among geographic populations and even subspecies, this may include ecological or reproductive aspects that need to be taken in account for specific conservation actions.
