This species is known from south-western Zapotitlán de las Salinas, central Puebla, and northern Oaxaca, Mexico. It might occur more widely than is currently known. It occurs at about 1,500m asl.
Habitat and Ecology
This stream-breeding amphibian inhabits temporary streams with rocks and arid scrub vegetation that provide suitable microhabitats. It seeks refuge in bromeliads during the dry season.
It is a common species.
The major threat is the ongoing disturbance and loss of the species' arid tropical scrub habitat due to infrastructure development, partly due to the construction of tourist facilities.
The range of this species includes Reserva de la Biósfera del Valle de Tehuacán-Cuicatlán.
Red List Status
Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat in Puebla and Oaxaca, Mexico.
This species was previously included in the genus Hyla but has recently been moved to the resurrected genus Exerodonta (Faivovich et al. 2005).
