Specimen labels

Nests are found under stones and logs (as well as in logs), usually banked with thatching, or simply in thatched nests. Reproductives were collected in nests from July to September. This species enslaves Formica neorufibarbis. (Mackay and Mackay 2002)


Workers have at least a few blunt tipped or spatulate hairs on the dorsum of the pronotum. The scapes, underside of the head, and petiole lack erect hairs. The gaster has only a few erect hairs, and the surfaces are sparsely covered with silver, appressed pubescence. The head and mesosoma are red, the gaster black. (Mackay and Mackay 2002)
