A New Subspecies of the Fruit-eating Bat, Sturnira ludovici, From Western Mexico

A meticulous field study reveals a previously unnoticed subspecies of fruit‑eating bat nestled in the highlands of western Mexico. Researchers gathered dozens of specimens during summer netting expeditions, noting distinct measurements, coloration, and cranial features that set these bats apart from their better‑known relatives. The description highlights a smaller overall size, a broader skull, and a drab brown coat that lacks the bright epaulets seen in nearby species.

Beyond the technical details, the work places the new population within a broader pattern of geographic variation among tropical bats, where northern individuals tend to be more diminutive. By mapping its range from Durango down to Jalisco, the study opens the door for further surveys in central and eastern Mexico, underscoring how even well‑explored regions can still hide surprising biodiversity.
