Fig 8. Maximum-likelihood phenogram based on allele frequencies calculated with four microsatellite loci for the 51 populations of H. obsoletus (722 individuals).

Individuals were associated with Convolvulus arvensis and Urtica dioica (green branches), Vitex agnus-castus (blue branches) and Crepis foetida (red branches) from Southeastern Europe and Turkey analyzed in this study and for the Israeli population associated with V. agnus-castus [7]. Hyalesthes luteipes was used as an outgroup to root the tree. The two most divergent populations of the Crepis foetida-associated genotype group from east Turkey (Cf-TR) and the Vitex agnus-castus-associated genotype group from Israel (V-IL) are designated.
