Biology:

This species occurs in cloud forest, from 1050–1400 m elevation. It is known only from the slopes of Volcán Atitlán, where it is sympatric with R. isthmica. At the type locality it seemed to occur just below the zone of high abundance of R. isthmica, at the lower edge of the cloud forest and at the transition to extensive coffee plantations at lower elevations. The six known specimens are from Winkler samples of sifted leaf litter.
