The chacoan forms, while difficult to subdivide further on the basis of external worker morphology, show two distinct nest phenotypes in reproductively mature colonies. I have observed these nest forms within a few meters of each other. One form constructs large, conspicuous crater mounds while the other has cryptic nest entrances in the soil consisting of a single small hole with a slight scattering of excavated earth placed up to half a meter away, a pattern similar to the nests of
