This species is known from the northern versant of the Sierra Juárez (at 1,600-2,180m asl), near the crest of the Sierra Juárez (Cerro Machín and Cerro San Felipe) (at 2,370 and 2,670m asl), and the Sierra Mixes (at 2,121-2,568m asl), Oaxaca, Mexico. It might occur a little more widely.
Habitat and Ecology
It inhabits cloud forest and pine-oak forest at high elevations. Adults may be found close to forest streams or in arboreal bromeliads. The larvae have been found in pools in streams.
The population status of this species is unknown.
It is presumably threatened by the conversion of forest habitat to agricultural land, and by logging. Chytridiomycosis may also pose a threat, as it is a high-elevation stream-dwelling amphibian, and declines due to the disease have already been detected amongst other species of this genus.
It is not known if the species occurs in protected areas, but the montane pine-oak forest habitats of Mexico in general are poorly protected. Further survey work is needed to determine the population status of this species, and whether chytrid is a threat.
This species was previously included in the genus Hyla but has recently been moved to the genus Plectrohyla (Faivovich et al. 2005).
