Natural History:

Members of the genus are all predaceous, with a static pressure mode of attack (Bolton 1999).

In Costa Rica, this species occurs in wet forest habitats. It is apparently rare and/or difficult to collect. Most collections have been from mid-elevation wet forest (around 500m) on either slope. I have twice collected the species using Winkler bag extraction from sifted forest floor leaf litter. One collection was from Carara and the other from Hitoy Cerere. These were the only occurrences among dozens of sifted litter samples that I have examined from throughout Costa Rica. I also collected a small colony in Braulio Carrillo National Park. It was in a rotten stump at the forest edge.
