Camponotus germaini is a soil-nesting species recorded from low forests, second growth forests, and edge habitats. Emery (1911d) distinguished C. tacuruensis from C. germaini on the basis of size and head shape of the major worker. I have examined Emery’s types for both taxa. Although it is true that C. germaini tacuruensis is slightly larger than most collections of C. germaini in Paraguay, I can find no other difference to distinguish C. tacuruensis . The head shape of the major worker in spite of Emery’s written description is scarcely different between the two forms and both forms fall within the observed range of variation of this species in Paraguay.
