Subgenus relationships in the previous and new phylogenetic reconstructions of the genus Lasius. Subgenera abbreviations: Acanthomyops (Ac), Austrolasius (Au), Cautolasius (Ca), Chthonolasius (Ch), Dendrolasius (D), Lasius sensu stricto (L). The topologies were extracted from papers by Wilson , "W55", Hasegawa , "H98", and Janda and coworkers , "J04", as well as from the Bayesian tree of combined, concatenated data in Fig. 2 of this paper, "new"; see Methods section for details of the procedure used for inferring the topologies W55, H98, and J04. A dotted line indicates that node support for monophyly of the subgenus was not significant. White squares indicate constraints enforced in constraint analyses using our concatenated data set in order to test the subgenus relationships of W55, H98, and J04.
