Phylogenetic tree of Mantophryne
(A) Island connectivity with sea level change. Present-day emergent land is coloured for cluster membership inferred with DAPC (see B), and islands unsampled in this study are shown in white. Sampling localities are shown by green dots. Elevation (above sea level) is shown by contour lines (200 m spacing). Smaller islands (Ste. Anne and Curieuse) are circled for clarity. The grey shaded area represents exposed land, with the shade of grey in the key indicating metres below current sea level. Bathymetry data from the GEBCO 2024 repository. Inset map shows position of the Seychelles (indicated with a green loop) relative to Africa. Latitude and longitude given in decimal degrees. (B) DAPC of K = 4, with eight PCs and two eigenvalues. (C) Hypogeophis rostratus, photographed by STM.
