This species is known from three different collections, all from the same locality. They were collected at the 1070m site on the Barva transect in Braulio Carrillo National Park. This is a very wet forested site. The three collections were from the ALAS project. Two were Winkler samples of sifted leaf litter from the forest floor; one was in a pan trap on the ground.
