Phylogeny

Chronogram of the D. virilis group of species obtained with the BEST topology. The alternative topology obtained with MP, ML and BI, which differs in the position of D. littoralis that is placed as sister species to the virilis phylad, is shown with a dashed line. Times in MY for the different cladogenesis events are shown inside the nodes in bold; the first is the age obtained for the BEST tree and the second is the age obtained for the Bayesian tree. Numbers in italics outside nodes correspond to the node numbers of Table 4 in Morales-Hojas et al. (2011).
