T. mexicana ranges from southern Mexico in the north of its range, through Central America as far south as northwestern Peru and northwestern Venezuela. It ranges from sea level to 2,000 m asl, although most sightings have been recorded from areas below 1,000 m asl (Cuarón 2005, Cuervo-Díaz et al. 1986, Eisenberg 1989, Tirira 2007).
