Table 2. Pairwise genetic distances between individual sequences within and between mitochondrial units, based on our data set of 159 COI sequences (Table 1). Ranges of minimum to maximum distances are indicated (as percentages). For instance, within P. tumidus (Semper, 1880) unit #1, individual sequences are between 0 and 3.2% divergent; individual sequences between P. tumidus unit #1 and P. boholensis gen. et sp. nov. unit #2 are minimally 6.4% and maximally 7.9% divergent; also, overall, the distance gap between P. tumidus unit #1 and the eight other mitochondrial units is between 3.2% (the maximum intra-unit distance within P. tumidus unit #1) and 5% (the minimum distance between P. tumidus unit #1 and P. tumidus unit #3). The data from this table are illustrated in Figure 5 to help visualize the large gap between intra-specific and inter-specific distances.
