Maximum statistical parsimony network of Bembidion species sharing COI haplotypes: A Bembidion atrocaeruleum Stephens, 1828 and Bembidion varicolor Fabricius, 1803 B Bembidion guttula (Fabricius, 1792) and Bembidion mannerheimii C.R. Sahlberg, 1827. Used settings included a user specified maximum of connection steps at 50, gaps were treated as fifth state. Each line represents a single mutational change whereas small black dots indicate missing haplotypes. The numbers of analyzed specimens (n) are listed, whereas the diameter of the circles is proportional to the number of haplotypes sampled (see given open half circles with numbers). Scale bars = 1 mm. Beetle images were obtained from www.eurocarabidae.de.
