Comments. The Mexican workers differ slightly from the Costa Rican ones. The head sculpturing is rugulate to rugo-reticulate posteriorly. The apical and subapical teeth on the masticatory margin are bigger than the basal and sub-basal teeth, and the promesonotum of the queen is smooth and shining (sculptured in Costa Rican queen). However, I consider these differences to be geographical variation, not worthy of species status. New collections in the areas between Mexico and Costa Rica (including queens and males) may clarify whether or not we are dealing with more than one species.
