The geographic and elevational distribution of the genus Natalus Gray, 1838 (Mammalia, Chiroptera) in Guatemala, including the first record of N. lanatus Tejedor, 2005

We document the first confirmed record of Natalus lanatus from Guatemala, increasing the national bat fauna to 107 species, and present the first country-level synthesis of the geographic and elevational distribution of the genus Natalus . Morphological analyses of N. lanatus ( n = 8) and N. mexicanus ( n = 8) show clear differentiation, with the first two FAMD dimensions explaining 61% of total variance. Voucher-based records further show elevational segregation, with N. lanatus occurring at 731–2,573 m and N. mexicanus from near sea level to 523 m.
