Range
Venezuela, Costa Rica, Mexico (Chiapas). In Costa Rica I have seen specimens only from the Osa Peninsula region, in spite of extensive collecting elsewhere.
Identification
Antennae 7 segmented; face somewhat shiny, not mat or punctate; interantennal lamella subtriangular in lateral view; lamella relatively smaller compared to humilis, a tooth originating between antennal insertions, well above anterior margin of clypeus, such that in side view lamella is usually not visible, obscured by antennal scapes; clypeus projecting relatively less beyond mandibles compared to humilis.
Notes
For general observations on biology of genus, see horni.
In Costa Rica, I have collected workers of this species from three different Winkler samples from three different sites on and near the Osa Peninsula: Sirena, Rancho Quemado, and a site 19km S of Ciudad Neilly.
