Bayesian phylogenetic inference tree of Udea, based on genetic and morphological data. Numbers on the branches represent posterior probabilities (PP) ≥ 0.9, scale bar represents substitutions per site; note that for the taxa marked with an asterisk (*), the analysis was done with morphological data only. The sampled African Udea species are marked in bold, Udea species groups sensu Mally and Nuss (2011) are indicated on the right.
