Phylogenetic tree based on maximum likelihood inference of combined Bloc, RPB1, Tef1 data. Value above branches = Maximum likelihood bootstrap values (BS) / Bayesian posterior probabilities. Grey bars represent species delimitation results from ABGD-, SPN-, GMYC- and BPP based algorithmic methods based on Bloc, RPB1, and Tef1 sequences. Scale bar indicates the number of nucleotide substitution per site. a: delimited as the same species. B. araneola, B. gryllotalpidicola, B. loeiensis, B. medogensis, and B. rudraprayagi were not delimited by any DNA-based algorithm due to abundant missing data in their sequences.
