Diagram to help visualize the data on pairwise genetic distances between COI sequences within and between species and mitochondrial units (P. verruculata) in Peronia (see Table 3). Ranges of minimum to maximum distances are indicated (in percentages). For instance, within P. willani, individual sequences are between 0 and 1.9% divergent; individual sequences between P. willani and the other species or units are minimally 4.3% and maximally 16.8% divergent. The colors are the same as those used in Figs 2–4, 6.
