Description
With Pheidole camptostela, unique within Pheidole for the sharply bent petiole and depressed petiolar node, as seen from the side, in both major and minor. Distinguished from camptostela by the less exaggerated form of the petiolar modification, the presence of rugoreticulum on the head of the major, and the broader, less concave occiput of the minor.
