impaternata is a unisexual clonal species of hybrid origin, arguably with a gynogenetic mode of reproduction in which (i) the parthenogenetic production of diploid female eggs by its queens is spermdependent, requiring allospecific copulation followed by interaction without fertilisation between their unreduced oocytes and nonconspecific sperm cells and (ii) sperm necessary for this purpose is likely acquired by the gynes through copulation with technically allospecific males produced from eggs laid by impaternata queens and reared in impaternata nests.
