Identification
Worker: This is a common bicolored species, having a dark brown head and gaster with a lighter colored mesosoma, usually golden yellow, but some may be light brown. The antennal scapes are short (1.02 mm) and surpass the posterior margin of the head by less than twice the maximum thickness of the scape. The scape has few short, decumbent hairs (no more than 20). The longest erect hairs are on the dorsal surface of the pronotum (0.26 mm in length). The mesosoma is convex with the highest point at the mesonotum.
