is a montane species. The lowest elevation record is 950 m in Panama, and the highest record is 2000 m in southern Peru. It has been collected most often in mature cloud forest and montane oak forest habitats, but has also been collected in litter beneath cultivated coffee. All collections are from Berlese and Winkler samples of sifted litter and rotten wood from the forest floor.
