Identification

This is an attractive, bicolored ant (head and mesosoma red, gaster black), in which the mid and hind tibiae normally have only 1 or 2 erect or suberect hairs, located near the apices of the tibiae. The scapes are without erect hairs (except at the apex). The clypeal fossa is shallow and the surface of the clypeus is broadly convex. The suberect hairs on the gaster are widely scattered and sparse. (Mackay and Mackay 2002)
