Abstract

We compared intranidal variation in worker size in the two closely relatedplant-ants Aphomomyrmex afer and Petalomyrmex phylax. Each of these generais monotypic, and the two appear to be sister species among extant ants. Workers of A. afer are larger on average and exhibit much greater intranidalsize variation. Workers of P. phylax are smaller and much less variable insize. Both species show weak allometry for some pairs of characters. Head shape is also different in workers of the two species. We discuss these differences in relation to the ecology of A. afer and P. phylax, and propose ascenario for the evolutionary divergence of worker morphology in these twospecies. Based on comparisons of these two monotypic genera with related ants, we suggest that reduced intranidal variation in worker size is a derived trait in Petalomyrmex.
