Natural History

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

The single known specimen is from La Selva Biological Station. It was from a 10cm deep soil/litter core placed in a Berlese funnel. The soil core came from trap site 3 of the ALAS project, La Selva GIS 1498/1848 (along Hartshorn trail), a site with old-growth wet forest on alluvial soil.
