FIGURE 18. Phylogenetic relationship among the species of the Rhyacophila fasciata Group included in this study. Combination of bayesian phylogenetic and maximum likelihood trees based on COI. Support for each node is represented by the posterior probabilities (PP) resulting from the Bayesian inference analysis and the bootstrap support values (BS) obtained for the maximum likelihood tree (PP/BS). Rhyacophila cf. obliterata (Robl) (18a), outgroup; Rhyacophila fasciata Group: Rhyacophila kykladica Malicky & Sipahiler 1993 (Rkyk) (18b), Rhyacophila macedonica Karaouzas, Valladolid & Ibrahimi (n. sp.) (Rmac) (18c), Rhyacophila fasciata Hagen 1859 (Rfas) (18d), Rhyacophila denticulata McLachlan 1879 (Rden) (18e), Rhyacophila sociata Navás 1916 (Rsoc) (18f), Rhyacophila fasciata viteceki Valladolid & Kučinić 2020 (in Valladolid et al. 2020) (Rfvit) (18g), Rhyacophila fasciata delici Kučinić & Valladolid (in Valladolid et al. 2020) (Rfdel) (18h), Rhyacophila septentrionis McLachlan 1865 (Rsep) (18i).
