Mexico south to Costa Rica, many Caribbean islands. Uncertain whether native in Costa Rica.
Shiny black throughout. This species is superficially similar to shiny black Solenopsis, but is separable by the 3-segmented antennal club.
In Costa Rica this is a moderately common species in disturbed areas in the seasonally dry northwest portion of the country. I have collected it in Santa Rosa National Park, where I observed workers recruiting to a dead grasshopper on an asphalt road. I also have records from Curu on the Nicoya Peninsula and La Pita on the road from the PanAmerican highway to Monteverde. I have never found a nest of the species.
