This species is known only from a very restricted area to the north and south of Putla town in extreme western Oaxaca, Mexico, at 800-1,400m asl. Extensive surveys for the species have not been conducted and it might occur more widely.
Habitat and Ecology
It lives in secondary tropical semi-deciduous forest, as well as in shaded banana and coffee plantations. It is arboreal, and most specimens have been collected in the leaf axils of red banana trees and other large-leaved plants. It reproduces by direct development.
It is an uncommon species.
This species appears to be relatively resistant to habitat modification (taking place across the range due to logging and agriculture) and occurs in shaded plantations, though even these habitats are threatened as a result of shifting agricultural practices - specifically the change from red bananas to yellow bananas as a crop of choice.
It is not known from any protected area, making the protection of forest habitat for this species a priority. Efforts should be made to encourage red banana cultivation. It is protected by Mexican law under the "Special Protection" category (Pr).
Red List Status
Listed as Endangered because its relatively small range (<5,000 km2) has largely been deforested in the past and the remaining artificial habitat (red bananas) is being replaced and fragmented by yellow bananas.
