This species is known from the mountains of the Atlantic slopes of eastern Chiapas (Mexico) and northern Guatemala. In Guatemala, it occurs in the Sierra de Los Cuchumatanes, Alta Verapaz highlands, and the Sierra de Santa Cruz. Its altitudinal range is 140-1,500m asl. It probably occurs more widely in this range than current records suggest.
Habitat and Ecology
It lives in cloud forest and pine-oak broadleaf forests, but is somewhat adaptable and has been found under rocks in gardens and in coffee plantations. During dry periods it hides in arboreal bromeliads up to 5m above the ground. It breeds by direct development.
It is an uncommon species.
The main threat is habitat loss due to expanding agriculture (livestock), wood extraction, and human settlement, which results in the opening up, and hence drying out, of its habitat.
It has not been recorded from any protected areas, and there is a need for improved protection of pine-oak forest habitats in the range of this species.
