Notes

Cardiocondyla are tiny myrmicine ants which live in colonies consisting of several dozen to a few hundred workers. Queen number varies by species. Nests are commonly in the soil, less so under rocks and in just a few species are known to be made in vegetation. Open arid habitats are favored by many Cardiocondyla. Several species are well known tramp species
