Species identification tree as derived from the mitochondrial DNA sequence of the COI barcoding gene of 25 specimens previously assigned to Anthidium undulatum. The gene sequences are divided into three groups, which are assigned to A. undulatum Dours, 1873; A. wahrmani (Mavromoustakis, 1948) stat. nov., and A. libanicum Kasparek sp. nov. (see text).
