Etymology: The genus name was coined in 1829 by the German zoologist Johann Jakob Kaup, who needed a Latin label for a group of small bats. He took it from the Italian "pipistrello," meaning bat, and gave it a Latin form with the diminutive ending "-ellus," so the name roughly means "little Italian-style bat." The Italian word is itself a folk-style term whose exact origin is uncertain. It is often linked to the Latin "vespertilio," meaning bat, though the route from one to the other is not fully clear. The name stayed in scientific use because it was short and easy to Latinize. Zoologists later used the same root for the common species name, which is why the familiar English "pipistrelle" is a borrowing of the Italian form. The genus was given its formal name long after the bats themselves were described, so the name records a 19th-century classification rather than any ancient naming tradition.

Synonyms: bat, vesper bat
