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 cinnamon red bat is a species of bat in the family Vespertilionidae. It was first described from a specimen that had been collected in Chile. For more than one hundred years after its initial description, it was largely considered a synonym of the eastern red bat. From the 1980s onward, it was frequently recognized as distinct from the eastern red bat due to its fur coloration and differences in range. It has deep red fur, lacking white "frosting" on the tips of individual hairs seen in other members of Lasiurus. It has a forearm length of 39–42 mm (1.5–1.7 in) and a weight of 9.5–11.0 g (0.34–0.39 oz).
