The BI phylograms constructed from ITS2 and COI sequences and used for the PTP analysis after discarding the outgroup. Numbers at nodes indicate Bayesian posterior probability values; values below 0.90 are not shown. Species of the ‘P. richtersi’ and ‘P. areolatus complexes’ are indicated by blue and red branches, respectively, whereas outgroup taxa are marked with black. Each terminal node on the COI tree represents a separate species delimited by the PTP, as well as by the ABGD method, whereas on the ITS2 tree two putative species are represented by multiple nodes (indicated by brackets). Please note that although in both trees the ‘P. richtersi complex’ is monophyletic, in the ITS2 tree, the ‘P.areolatus complex’ is polyphyletic, whereas on the COI tree it is paraphyletic. Please see Supporting Information, Table S3 and ‘Phylogenetic analysis’ subsection in Material and Methods for details on sequences used in the analyses. Scale bars represent substitutions per position. Highlighted are sequences for Paramacrobiotus areolatus s.s. (Murray, 1907).	Figure 7.
