FIGURE 8. A Bayesian inference (BI) tree of 16 S rDNA for the subfamily Potamiscinae, with the sequences and accession numbers in Shih et al. (2009), as well as some additional species (see Material and methods). The species inhabited in Chinese caves are highlighted in gray. Probability values at the nodes represent support values for BI and maximum likelihood (ML). Only values> 50 % are shown.
