This species occurs in Pacific lowlands and foothills from extreme eastern Oaxaca, east of the plains of Tehuantepec, Mexico, through Guatemala southward to central El Salvador. Another population occurs at the Cintalapa Valley in southwestern Chiapas (0-700m asl). It probably occurs more widely than current records suggest, especially in areas between known sites.
