Maximum likelihood tree based on DNA barcode data, constructed with IQ Tree. The results of the species delimitation analyses are summarised on the right. Black boxes indicate congruence with our morphological examinations, while the red boxes highlight disagreements. Species and species groups are named according to the results of our integrative taxonomy approach (see corresponding treatments). The dotted line is connecting the outgroup, Aegilips sp., to the remaining tree and is not to scale. Identical sequences from the same sites are combined in respective tip labels and are indicated with a (+ n). Ultrafast-bootstrap support is shown on the nodes.
