Abstract: 【Objective】 Through studying the numerical taxonomy of the species of Phlebotominae from China to explore the phylogenetic position of these species in Phlebotominae.【Methods】 Cluster analysis was carried out with 40 species of Phlebotominae from China as taxa and 68 morphological characters as index.【Results】 The result of cluster analysis is consistent with classic taxonomy in the genus classifications of Phlebotominae and subgenus classifications of genus Phlebotomus, while there are some differences in the subgenus classifications of genus Sergentomyia which is divided into 8 groups by cluster analysis. Two of them are respectively identical with subgenus Sergentomyia and nicnic group in classic taxonomy. S. quanzhouensis and S. tangi unite with subgenus Parrotomyia. S. yini is separated into subgenus Neophlebotomus. S. iyengari, S. malayensis, S. lanzhouensis, S. nankingensis and S. turfanensis aggregate as a group. S. koloshanensis, S. fanglianensis, S. yunnanensis and nicnic group unite as a group which has a far phylogenetic relationship with that composed of other species of genus Sergentomyia. 【Conclusion】 The result of cluster analysis of Chinese Phlebotominae is consistent with classic taxonomy on the whole. It confirms the reliability of classic taxonomy and also reveals the uncertain classification of some species in genus Sergentomyia in classic taxonomy. The difference between the two classifications of genus Sergentomyia suggests that refining the taxonomic position of some species and founding a new multispecies genus or subgenus or group at the subgenus level are essential.
