Areas are coded by mountain block as follows: EU = East Usambara, NG = Nguru, UL = Uluguru, SH = Southern Highlands, MU = Mu, NA = Namuli, UD = Udzungwa, RU = Rubeho, WU = West Usambara. BFD: Log likelihood values (lnL) are given for potential species grouping scenarios for path sampling (PS) and stepping stone analysis. Bayes Factors of each progressively more likely scenario are shown (BF). Bayes Factors above 10 are considered “decisive”. Top models from each analysis both predict six species, though BPP lumps H. davenporti and H. burgessi and splits the two populations of H. spinigularis
