Costa Rica (500m elevation on Cordillera Volcanica Central).
Mesosomal dorsum with erect hairs; opening of propodeal spiracle viewed perpendicularly slit-shaped, more than twice as long as wide; mandible with approximately 17 teeth; dorsal outline of mesosoma interrupted by a distinct, impressed propodeal groove, so that the mesonotum forms a convexity separate from the more or less convex propodeal dorsum; in full-face view, a line drawn through the centers of the eyes falls near mid-head, crossing near posterior limits of frontal carinae; cheeks with a distinct carina reaching from clypeal wing to eye margin; anterior face of petiolar node somewhat sloping to rounded apex, dorsolateral margins weak but present; posterior margin of head broadly and strongly convex.
Similar species: dismarginata.
This species is only known from a series of workers collected in two different Malaise traps. The Malaise traps were part of the Project ALAS sampling at the 500m elevation (El Ceibo) site on the Barva Transect in Braulio Carrillo National Park.
