Mexico south to Costa Rica, many Caribbean islands. Uncertain whether native in Costa Rica.


Natural History:

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.

Taxonomic Treatment (provided by Plazi)

Fernández, F., 2007:
This species is similar to M. compressum and, to a lesser extent, to M. cyaneum . A characteristic that appears to separate it from similar species is the petiolar profile, which in frontal view is flat to weakly concave.
