Taxonomy and etymology

It was described as a new species in 1860 by Swiss scientist Henri Saussure.[3] Its species name "aztecus" refers to the indigenous Aztecs of Mexico, where this species was first documented.

Description

It is one of the smallest bats of the genus Molossus. Its fur is chocolate brown and its patagia, nose, and ears are very dark brown. Individuals weigh 12–16 g (0.42–0.56 oz). Its forearm length is 34–35 mm (1.3–1.4 in). Its dental formula is 1.1.1.31.1.2.3 for a total of 26 teeth.[4]

Biology and ecology

It is nocturnal, foraging for its insect prey at night and roosting in hollow trees during the day. Unusually for its genus, females may become pregnant while still nursing a pup.[4]

Range and habitat

It is endemic to Mexico. It is generally documented at elevations greater than 1,500 m (4,900 ft) above sea level.[4]
