Figure 2

Parsimony-based haplotype-network of mitochondrial COI sequences from 36 studied Lethrus apterus populations obtained by TCS. Each recovered haplotype is numbered at its position on the network (either in the circle or next to it). Dots represent unsampled (extinct) haplotypes. Shaded haplotypes appear as a statistically supported (Bpp = 0.95) monophyletic clade on Fig. 3 and are geographically confined to the Hungarian Middle Range (on the western part of the distribution area).
