Fig. 2 in Big and beautiful: the Megaxyela species (Hymenoptera, Xyelidae) of East Asia and North America

Fig. 2. Phylogenetic hypothesis of Megaxyela Ashmead, 1898, based on a Maximum Likelihood analysis of the barcoding region (COI-5P) applying the the Jukes-Cantor model. Two specimens of Macroxyela ferruginea (Say, 1824) have been included as outgroup. See Material and Methods for details. Bootstrap values above 50 % are shown next to the concerning nodes. The labels of the individual specimens consist of species name, voucher number (for Megaxyela identical with the DEI-GISHym numbers used in the text, for Macroxyela GenBank accession number), sex (♀ for females, ♂ for males) or larva, country and province of origin, and sequence length.
