A minireview of the bat richness in the state of Tlaxcala, Mexico

Abstract

Given that Tlaxcala lacks an updated inventory of its chiropteran fauna, information gaps and advances in the taxonomy and distribution of the species, this work presents the first documented synthesis for the state, with the aim of providing a solid basis for future research on biodiversity, conservation, and environmental health. In Tlaxcala, 24 bat species have been recorded, three of which are endemic to Mexico (Corynorhinus mexicanus, Dermanura azteca, and Natalus mexicanus). According to PROY-NOM-059-SEMARNAT-2025, two species are listed as endangered (Leptonycteris nivalis and Choeronycteris mexicana). These mammals provide key ecological functions such as pollination, seed dispersal, and insect control, contributing to ecosystem balance. The absence of local protection programs highlights the need to implement comprehensive management and outreach strategies that promote the recognition of bats as indispensable allies for biodiversity and agriculture in Tlaxcala.
