Figure 6 in Integrative taxonomy using historical specimens provides evidence for a single species of bushbuck, Tragelaphus scriptus (Mammalia: Bovidae)

Figure 6. Phylomorphospace shows poor correspondence between mitogenomic relationships and morphological differences. Axes refer to the first and second principal components (PC1 and PC2) of the geometric morphometric analysis. The key is the same as that shown in Figure 1; labels refer to specimens in Table 1. Note that this figure includes only specimens for which mitochondrial DNA was extracted.
