Description
Plateaux, L. & Cagniant, H. 2012: 436: We conclude from all these observations that Leptothorax tuberum unifasciatointerruptus is a hybrid of Temnothorax unifasciatus and Temnothorax albipennis. Hybridization works in both directions, parents may be alternately of the two species, and males are from the parthenogenetic egg of the queen mother. Note that both species exist also in places (especially in Luberon and Ventoux) where the where the form was found. We therefore ask: T. albipennis x T. unifasciatus = L. tuberum unifasciatointerruptus Forel.
