Natural History:

Discothyrea are extremely small, cryptobiotic inhabitatants of forest leaf litter (see Genus Overview). 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.
