Fig. 1. Concatenated mitochondrial RaxML phylogram of the genus Nucras and outgroups used in this study. Bootstrap support (above) and posterior probabilities (below) are shown for the species level and more inclusive nodes. Select nodes containing individuals with identical or minor sequence divergence (less than 2%) from shared localities and from non-focal taxa have been collapsed in order to condense overall tree size; but a full list of the specimens used in this study can be found in Table 1.

FIGURE 5. Map of A) the distribution by quarter degree squares of Nucras tessellata in South Africa—yellow squares circles (from Bates et al. 2014, including virtual records but excluding questionable records) and Nucras aurantiaca sp. nov.—red squares; and B) close-up of the region of Lambert's Bay Strandveld vegetation type (teal coloration) occupied by N. aurantiaca (based on Mucina & Rutherford 2006). Red star is the type locality of N. aurantiaca sp. nov., red dot is the camera trap locality for the species.
