, Mexico Biogeographic regions
(According to curated Bioregion/Taxon lists): Neotropical
The types were collected by E. O. Wilson in leaf litter of dry, rocky, tropical evergreen forest. New material collected by the LLAMA project was in scrubby wet forest of eastern Chiapas and the seasonal evergreen forests of the Tikal region in Guatemala. All specimens were from Winkler samples of sifted leaf litter from the forest floor.
