在不到100种的庞氏蚁中，蚁后不再存在，取而代之的是交配产卵的工蚁。其他亚科的工蜂在除去蚁后可以产下单倍体卵，但它们从不进行有性繁殖。工蜂能够交配是因为它们在大多数物种中都有受精囊，外来雄性在它们的巢穴附近性活跃，它们的臀腺分泌物可以承担性的意义。此外，蜂后很少繁殖力很强，一只或几只加马格斯能够接近它们的产卵量。最后，殖民地分裂的机会会随着他们的生活史而发生，这是一个必要的前提条件，因为玩家不能独立地开始新的殖民地。这些特征中的许多与这个遗传学上原始的群体中所表现出的有限的种姓分化有关。虽然一些非ponerinae物种表现出一些这些先决条件，但在Ponerinae之外还没有发现gamergates，只有它们表现出导致女王消除和工人交配的特征。
In less than 100 species of ponerine ants, queens no longer exist and have been replaced by mated egg-laying workers. Workers in other subfamilies can lay haploid eggs when queens are removed, but they never reproduce sexually. Ponerine workers are able to mate because they have a spermatheca in most species, foreign males are sexually active near their nests, and their pygidial gland secretions can assume a sexual meaning. Furthermore, ponerine queens are seldom very fecund, and one or several gamergates are able to approximate their egg production. Finally, opportunities for colony fragmentation occur consequent to their life history, and this is a necessary precondition because gamergates cannot start new colonies independently. Many of these characteristics are associated with the limited caste divergence exhibited in this phylogenetically primitive group. Although a few non-ponerine species exhibit some of these preconditions, gamergates have not been found outside the Ponerinae, which alone exhibit the combination of traits leading to queen elimination and worker mating.
