Phylogenetic analysis of endosymbionts under “ Candidatus Neoehrlichia” subregion in Otiorhynchus spp. The tree represents the “Candidatus Neoehrlichia” subregion of the complete tree (see additional file 1: 16S rDNA gene-based phylogeny of endosymbionts in four different Otiorhynchus spp. larvae) and was constructed by using parsimony algorithm. Sequences obtained in the present study are coloured. The amount of sequences included in the groups of Wolbachia, Ehrlichia, „Candidatus Neoehrlichia” and Anaplasma are indicated by numbers.
