This species is known only from Sierra de Los Tuxtlas, southern Veracruz, Mexico. The type locality is recorded as 900-1,200m asl.
Habitat and Ecology
The primary habitat is lowland tropical humid rainforest; it seems to live on the ground and under leaf-litter. Breeding takes place by direct development.
It is an uncommon species.
The high rate of transformation of original forest habitat in this area is notorious, and deforestation for the cultivation of coffee, fruits and tobacco is rapidly increasing.
The range of this species is wholly within Reserva de la Biósfera Sierra de Los Tuxtlas, although logging is taking place within this area. A survey to evaluate the population status of this population in Los Tuxtlas is needed, and real protection of the Sierra de Los Tuxtlas and the surrounding areas is urgent. This species is protected by Mexican law under the "Special Protection" category (Pr).
