Abstract Matriline and the predominant social tasks performed by workers are correlated in the functionally polygynous ponerine ant Gnamptogenys striatula. This result favors the idea that polygyny might have been secondarily selected and maintained in ants because it provided more genetic variability and, thus, more potential variation in the regulation of the division of labor within mutualistic societies. As in previous studies on ants, nepotism could not be demonstrated. Because of the relatively small number of individuals per colony, these ponerine ants constitute a valuable model for exploring how polyethism is determined in insect societies.
