Anochetus rectangularis

Group of rectangularis. Australian species of medium size with more or less axially compressed petiolar node; in 3 of the species, nodal summit transverse and concave in the middle, the free angles forming teeth in one of these species (paripungens, rectangularis, armstrongi). In the fourth species (turneri) the node is thick and rounded above (fig. 33), but this species seems otherwise related to rectangularis.Published as part of Brown, WL Jr.,, 1978, Contributions toward a reclassification of the Formicidae.
