Habitat
Leaf litter and subcortical . have been documented in montane forests, including cloud forest environments at elevations such as Cofre de Perote mountain.
Distribution
Primarily Neotropical Region. Documented from Mexico (Veracruz: Cofre de Perote mountain; Hidalgo: Xochicoatlán) with broader distribution throughout tropical Americas implied by leaf litter fauna surveys.
Behavior
Flightless due to condition. Associated with ground-dwelling habits in decomposing organic matter and under bark.
