Eyes composed of 1-3 facets (occasionally up to 6); in full face view eyes small enough to not break lateral outline of head; puncta on face similar in size to interspaces, face feebly shining; petiolar node tapering to a rounded summit; color usually dark brown, occasionally reddish brown. Measurement data.
Natural History
This species occurs in a wide variety of habitats throughout Costa Rica, from sea level to about 1000m elevation. Although most abundant in mature wet forest habitats, I have collected it in dry-forest riparian habitat at Finca La Pacifica in Guanacaste Province. The species occurs very often in Winkler samples of leaf litter from the forest floor. I rarely collect it by other means. At La Selva I found a nest in dead wood on top of large rotten log. At the Arenal Observatory Lodge I found a nest in rotten wood on the forest floor. At the Maritza Biological Station in Guanacaste Conservation Area workers came to honey/tuna baits on the ground.
