Range
Costa Rica: Osa Peninsula and Penas Blancas Valley in Cordillera de Tilaran.
Identification
Preorbital carina sinuous or straight, extending past eye and directed toward posterolateral vertex margin; in face view with distinct lateral and posterolateral tubercles, such that margins of head behind eye are not rounded; anterior pair of mesonotal spines short and blunt; frontal lobes evenly rounded.
Natural History
I know this species from three collections:
A Winkler sample from Refugio Eladio in the Penas Blancas Valley east of Monteverde.
A Winkler sample from Sirena in Corcovado National Park.
A series of workers from San Pedrillo in Corcovado National Park. The workers were carrying insect feces to a nest entrance in the soil. A dirt mound, 10cm across, was adjacent to but separate from the actual, cryptic nest entrance.
