Phylogenetic tree inferred from cytochrome B data of Phlebotomus chabaudi and Ph. riouxi specimens. We added to the analysis the sequences of Ph. chabaudi published by Tabbabi et al. (2014). The phylogram results from bootstrapped data sets obtained using the PhyML 3.0 program [21] using GTR (general time reversible) + Γ distribution (gamma distribution of rates with four rate categories). The tree was visualized using the TreeDyn program, version 198.3 [7]. The percentages above the branches are the frequencies with which a given branch appeared in 500 bootstrap replications. Only bootstrap values higher than 50% on the early branches are shown. A sequence of Ph. sergenti (AF161216) was used as the outgroup. The sequences marked by * were published by Tabbabi et al. (2014); R = sequences found in specimens morphologically characterized as Ph. riouxi. C = sequences found in specimens morphologically characterized as Ph. chabaudi. RC = sequences found in specimens morphologically characterized as Ph. chabaudi or Ph. riouxi. Int = sequences found in specimens morphologically characterized as intermediate between Ph. riouxi and Ph. chabaudi.
