Specimen labels

This species nests under stones.


Workers may be recognized by the lack of a process on the metasternum, being concolorous yellow to blackish-brown, by lacking elongate punctures on the genae, and in having erect hairs present on the ventral surface of the head, posterior border, promesonotum, propodeum and dorsal margin of the petiole. The four faces of the femora have erect hairs, and the petiole is thick as seen in profile, with a rounded apex. (Mackay and Mackay 2002)
