Thelytokous parthenogenesis in which diploid females are produced from unfertilized eggs, was recently reported for some ant species. Here, we document thelytokous reproduction by queens in the polygynous species Pyramica membranifera. Queens that emerged in the laboratory were kept with or without workers under laboratory conditions. Independent colony founding was successful for a few queens if prey was provided. All artificial colonies, which started with a newly emerged queen and workers produced new workers and some of the colonies also produced female sexuals. Some of the female sexuals shed their wings in the laboratory and started formation of new polygynous colonies. Workers had no ovaries and thus, were obligatorily sterile.
产雌孤雌生殖是指未受精卵发育成二倍体雌性个体，最近在一些蚂蚁物种中被报道。在此，我们记录了多蚁后物种膜翅棱胸切叶蚁中蚁后的产雌孤雌生殖现象。在实验室中羽化出的蚁后在有工蚁或无工蚁的实验室条件下饲养。如果提供猎物，少数蚁后能成功独立建立蚁群。所有由新羽化的蚁后和工蚁开始组建的人工蚁群都产生了新的工蚁，并且其中一些蚁群还产生了雌性有性个体。一些雌性有性个体在实验室中蜕掉翅膀并开始组建新的多蚁后蚁群。工蚁没有卵巢，因此必然是不育的。
