Figure 6 in Taxonomic inflation due to inadequate sampling: are girdled lizards (Cordylus minor species complex) from the Great Karoo one and the same?

Figure 6. Isolation by distance scatterplots for pairwise intra- and interspecific comparisons for Karoo cordylid lizards. (A) The Karoo taxa only (C.aridus, C. cloetei, C.minor) and (B) Karoo species compared to sister taxa (C.imkeae, C. macropholis). Intraspecific comparisons denoted by black dots. Interspecific pairwise comparisons: C. aridus/C. cloetei – triangles, C. aridus/C. minor – squares, C. cloetei/C. minor – circles, three Karoo species/C. imkeae – diamonds, three Karoo species/C. mclachlani – crosses. Isolation by distance trend is shown by the dotted line. Axes in A and B are not of the same range.
