Description
A member of the gertrudae group, easily distinguished in the major from the other two known members (Pheidole capillata, Pheidole gertrudae) by the extensive rugoreticulum on the head, transverse carinulae on the pronotal dorsum, and lack of any propodeal spine or denticle, with the basal and declivitous propodeal faces in side view forming a blunt right angle.
