Range
Costa Rica: Atlantic and Pacific slopes.
Identification
Antennae 9-segmented, so small it is hard to count the five segments between the two-segmented club and the larger first funicular segment; mesosoma strongly ankylosed; propodeal suture not impressed; propodeum short and sloping, without distinct dorsal face; petiole lacking anteroventral tooth; mesosomal and metasomal dorsa with abundant suberect pubescence, lacking erect setae or at lease these not clearly distinguishable from pubescence; color yellow.
Natural History
This is an extremely tiny ant. I know the species from two collections:
Costa Rica, Prov. Puntarenas, Osa Peninsula, Ranch Quemado: ex sifted leaf litter from wet forest floor (Winkler sample).
Costa Rica, Prov. Heredia, 17km N Vol. Barba, 800m (Barva Transect): ex sifted leaf litter from wet forest floor (Winkler sample).
