Neighbour-joining (NJ) topology of the analysed ground beetle species, based on Kimura 2-parameter distances. Triangles show the relative number of individual’s sampled (height) and sequence divergence (width). Numbers next to nodes represent non-parametric bootstrap values > 75% (1,000 replicates). Beetle images were obtained from http://www.eurocarabidae.de except for Agonum monachum (Duftschmid, 1812) (Photo taken by Lars Hendrich).
