FIGURE 10. Phylogeny of Asian forest scorpions (Scorpionidae: Heterometrinae Simon, 1879, stat. nov.), obtained by simultaneous phylogenetic analysis of 186 morphological characters and 4188 aligned DNA nucleotides from three mitochondrial and two nuclear gene loci (Loria and Prendini, in press). Maximum likelihood tree with unambiguous morphological synapomorphies optimized. Black circles indicate uniquely derived apomorphic states, white circles parallel derivations of apomorphic states. Numbers above circles indicate characters, numbers below indicate states (appendix 1).
