Figure 9 in Genetic and morphological studies of species status for poorly known endemic Trochulus phorochaetius (Bourguignat, 1864) (Gastropoda: Pulmonata: Hygromiidae), and its comparison with closely related taxa
Figure 9. The Bayesian tree for COI gene sequences assigned to Trochulus. Two sequences of Trochulus lubomirskii (= Trichia lubomirskii = Plicuteria lubomirskii) and one Petasina bielzi were also included as the out-group. Labels for Trochulus hispidus, Trochulus plebeius, and Trochulus phorochaetius were coloured in red, blue, and green, respectively. Additional acronyms beside the species name or an ampersand symbol '&' indicate 100% sequence identity for the joined names. Numbers at nodes, in the order shown, correspond to posterior probabilities estimated in MrBayes (MB), as well as bootstrap support values calculated in TreeFinder (TF), and PAUP using the weighted least squares (LS) method. Values of the posterior probabilities and bootstrap percentages lower than 0.50 and 50%, respectively, were omitted or indicated by a dash '-'.
