Phylogenetic tree of R. appendiculatus cox1 haplotypes. The evolutionary history was inferred by using the neighbor-joining method based on the Tamura 3-parameter model. A discrete Gamma distribution was used to model evolutionary rate differences among sites. Bootstrap values (> 80) are displayed above nodes. CH1-22 are haplotype names. The values in parentheses correspond to the frequency of each haplotype. KU725893 and AF132833 are GenBank accession numbers for R. appendiculatus sequences used as reference haplotypes from Kenya and Zimbabwe, respectively. Two species (R. eversti and R. microplus) obtained in this study and R. turanicus from GenBank (accession number: KU880574) were included as outgroups
