Fig. 16. A rooted maximum likelihood phylogeny based on sequences that combine mitochondrial COI and nuclear EF1-α including three xystodesmid genera. The phylogeny includes six sequences of Xystodesmus bifurcus sp. nov., eight of X. pallidus (Verhoeff, 1937), nine of X. shirozui (Takakuwa, 1942), two of Riukiaria koreana sp. nov., and three of Parafontaria koreana (Paik, 1963) obtained in this study, and two sequences of closely related species, Xystodesmus sp. PM-2015 and R. holstii (Pocock, 1895) which were retrieved from NCBI GenBank. Melaphe vestita Hoffman & Lohmander, 1968 was employed as an outgroup which was also retrieved from NCBI GenBank. The detailed information of sequences in the phylogeny is given in Supplementary Tables 1 and 3 (Supp. file 1). The numbers on the branches indicate bootstrap values (BP in ML phylogeny) and posterior probabilities (BPP in BI phylogeny) separated by a slash. The scale bar refers to a phylogenetic distance of 0.02 nucleotide substitutions per site.
