Costa Rica (Atlantic slope to 1200m and southern Pacific lowlands).
Occurs in mature wet forest habitats; nests in dead wood on forest floor, opportunistically in plant cavities, and under epiphytes; recruits to baits and extrafloral nectaries.
Types Mus. Comp. Zool. Harvard.
Major: mostly reddish yellow; head in full-face view subrectangular; posterior dorsal profile of head flat, not convex; premesonotal profile raised, semicircular; humeri from above subangular, extending beyond rest of pronotum below and only moderately prominent, along with mesonotal convexity in dorsal-oblique view; propodeal spines robust, more than half as long as the propodeal basal face anterior to them; all of mesosoma and most of dorsal surface of head foveolate and opaque; gaster completely smooth.
Minor: head subrectangular in side view; occiput broad and slightly concave; propodeal spines robust and half as long as propodeal basal face; all of head, mesosoma, and gaster foveolate and opaque; gaster completely smooth and shiny.

Range Atlantic slope to 1200 m and Pacific lowlands, Costa Rica (j. T. Longino 1997).
biology The species occurs in both lowland and montane rainforest, where the colonies nest both in dead wood on the forest floor and in live plant cavities and under epiphytes; workers have been observed attending extrafloral nectarines (Longino 1997).
