Table 2. Intra- and inter-unit pairwise genetic distances between the four mitochondrial units of Laspionchis based on our data set of 61 COI sequences (Table 1). Ranges of minimum to maximum distances are indicated (as percentages): e.g., individual sequences within L. boucheti are between 0 and 2.7% divergent, and individual sequences between L. boucheti and L. bourkei bourkei are minimally 8.6% and maximally 10.4% divergent. Overall, the distance gap between all four mitochondrial units is between 2.5% (the maximum intra-unit distance within L. boucheti and within L. bourkei matangensis) and 3.9% (the minimum distance between L. bourkei lateriensis and L. bourkei matangensis). Finally, the distance gap between the two species L. boucheti and L. bourkei is between 2.5% and 7.5%.
