Polyrhachis callima

Nests of P. callima, which are identical to those of Polyrhachis conciliata, are excavated in soil with entrances under pieces of wood, stone, or beneath tufts of grass. The holotype colony, which was almost completely excavated, contained 129 ants, including a dealate queen and a male.

Identification
At the type locality, Polyrhachis callima was sympatric with Polyrhachis conciliata. These species are superficially very similar and I originally considered them to represent a single species. However, closer examination revealed several characters clearly separating them. The most apparent difference is their pilosity which, in P. callima, is distributed almost evenly over the entire dorsum of the body, with the longest hairs reaching or exceeding the greatest diameter of the eyes in length. In contrast, the pilosity in P. conciliata is distinctly shorter and completely absent from the mesonotal and propodeal dorsa.
