Phylogeny of the Wormaldia occipitalis species complex. Species subgroups are marked and labelled with the corresponding name. Individuals are colour-coded by their morphological determination. Blue – W. occipitalis occipitalis, green – W. occipitalis meridionalis, gold – W. occipitalis x subterranea, red – W. subterranea, grey – W. sp. A Maximum likelihood based on the combined dataset (COI, wingless, CAD). Numbers on branches present bootstrap values >70 %. B Bayesian analysis based on the combined dataset (COI, wingless, CAD). Numbers next to the nodes present the node ages in million years.
