Maximum likelihood phylogenies of R. sanguineus s.l. ticks. Maximum likelihood trees based on partial R. sanguineus s.l. 12S rRNA (a) and 16S rRNA (b) sequences, rooted with R. turanicus sequences from NCBI GenBank. Ticks identified by diagnostic PCR as temperate lineage in orange, tropical in blue. Numbers at internal nodes represent support values from bootstrap based on 500 replications.
