Based on available sex-ratio data, and a few published laboratory proofs, it appears that thelytokous parthenogenesis is probably widespread in the oribatid mites. It is especially common in early-derivative taxa, such as the Desmonomata, where it seems to characterize whole families. Fifteen species of that group were proven capable of parthenogenesis

PARTHENOGENESIS occurs naturally in several orders of insects, and can conveniently be classified according to the sex of the offspring which develop from the unfertilized egg: (1) arrhenotoky—males only (fertilized eggs give rise to females); (2) thelytoky—females only; (3) amphitoky—both sexes.

Thelytokous reproduction by dealate queens in Monomorium hiten Terayama, 1996, collected from four islands of the Nansei Islands (Okinawa Prefecture, Japan) was confirmed in the field and laboratory. Dissection revealed that all dealate queens (N = 38) found in nine field collected colonies were uninseminated.

AbstractOnly recently has it become clear that several species of eusocial hymenopterans regularly reproduce by thelytokous parthenogenesis, that is, the production of diploid female offspring by unmated females. This phenomenon suggests that parthenogenetic reproduction might be advantageous to organisms under certain environmental conditions.

The Evolutionary Genetics of Thelytokous Parthenogenesis in Eusocial Hymenoptera
2014The phenomenon of thelytoky, the asexual production of diploid female offspring, is being increasingly uncovered among the eusocial Hymenoptera. Thelytoky is associated with a number of fascinating and novel reproductive systems. In this thesis I investigate the evolutionary and genetic consequences of thelytokous parthenogenesis, with particular focus
