Description

Pteronotus gymnonotus (Wagner, 1843) has its northernmost distribution records in southeastern Mexico, where it is classified as an endangered species. In this report we communicate two northernmost extralimital acoustic records of the species in the state of Veracruz, obtained in 2018 and 2022. The average constant frequency of echolocation calls of P. gymnonotus was 56.5 kHz in Boca Andrea and 53.88 kHz in Buena Vista. Acoustic detection surveys of the conspicuous echolocation calls of the species would help much in the detection of the species in roosts and foraging habitats.
