A Synopsis of the American Bats of the Genus Pipistrellus

This compact volume surveys the small, insect‑eating bats of the genus Pipistrellus across North America, from the Canadian border down to Honduras. Drawing on both historic museum collections and fresh specimens gathered in Veracruz over the past three years, the authors carefully document each species’ range, coloration, and key physical traits. Detailed descriptions of skull shape, ear structure, and dental patterns help readers see how these bats differ from their close relatives in the family Vespertilionidae.

The work presents side‑by‑side comparisons of the two recognized western and eastern forms, highlighting subtle variations in foot length, tragus shape, and tooth arrangement. Illustrated with a single figure and concise tables, the authors use these data to clarify long‑standing taxonomic ambiguities and suggest a more precise classification of the group. Listeners will come away with a clear picture of how scientists untangle species identities through careful anatomical study.
