Japanese house bat Pipistrellus abramus, photographed by Yushi Osawa.

Belongs within: Vespertilionini.

Pipistrellus, the pipistrelles, is a genus of small bats found in most of the Old World (including northern Australia) and North America. Most species of the genus have a distinctive weak, fluttery manner of flight that has been described as butterfly-like.

Characters (from Miller 1907): Dental formula I 2/3, C 1/1, Pm 2/2, M 3/3; teeth unspecialised. Outer upper incisor not as large as inner, but extending considerably beyond its cingulum. Inner upper incisor simple, or more often with a well-developed secondary cusp. Canines usually rather stout, posterior cutting edge of upper canine often, though not invariably, with incipient secondary cusp. Anterior upper premolar barely or not in toothrow. Skull similar to Myotis, though with tendency to greater breadth. External characters also similar to Myotis, except ear usually shorter and broader, tragus less acutely pointed, in some species bent forward at tip.
