Natural History:

Mackay described this species from five workers captured in a pitfall trap from Lomas Barbudal, a dry forest site in Guanacaste Province. He also reported a collection from 24km SW Cintalpa, Chiapas, Mexico. I collected a worker in a Winkler sample of sifted leaf litter from a small patch of riparian forest at Finca La Pacifica, also in Guanacaste Province. Specimens of M. smithii were in the same Winkler sample.
