Ecological Niche Divergence of speciation according to major habitat types. Left: Principle Component Analysis of current habitat suitability for each species. Montane grassland/forest mosaic species are on the right, while rainforest adapted species are on the left. Right: Distribution of forest (trees) and mosaic (grasses) adapted species on *BEAST species tree. A double-sided arrow between habitat types indicates the two nodes where ecological shifts are inferred. Relative population sizes based on field collection estimates and potential range sizes are shown in the relative size of color-key circles. The split distribution of H. spinigularis is represented by two circles to represent the two distant populations in Malawi and Mozambique separated by ~160 km. The two localities of H. tanneri are represented by a single circle as they are within the same mountain block and separated by only ~25 km
