Lesser Long-nosed Bat

The lesser long-nosed bat (Leptonycteris yerbabuenae) is a medium-sized bat found in Central and North America. It is sometimes known as Sanborn's long-nosed bat or the Mexican long-nosed bat, though the latter name is better avoided since it is also used for the entire genus Leptonycteris and for one of the other species in it, the greater long-nosed bat (L. nivalis).

Originally described as a subspecies of the greater long-nosed bat, it was later considered a subspecies of the southern long-nosed bat, before being confirmed as a distinct species. Enthusiasts for the bats often refer to them simply as leptos because they are the best known members of the genus Leptonycteris. The scientific name is derived from the type locality, near Yerbabuena in Guerrero, Mexico.
