    AnnotationPhylogeny of ants of the tribe Lasiini (Lasius, Acanthomyops, Prenolepis, Euprenolepis, Paratrechina, Pseudolasius, and Myrmecocystus) was analysed using morphological and molecular data sets. Resulting tree topology is congruent with two alternative scenarios of origin of the temporary social parasitism: (i) a single origin of the parasitic strategy in a derived subclade of Lasius and a secondary loss of this trait in Cautolasius, (ii) a parallel origin of the social parasitism within the Chtonolasius and Acanthomyops + Dendrolasius + Austrolasius. Emery’s rule in the strict sense does not apply to this group because most parasites exploit any ecologically available, even phylogenetically distant host species.The parasitic strategy in Lasius could have originated from the aggressive interactions between cofounding queens during pleometric colony founding and/or from the secondary queen adoption.
