Abstract:Macropsinae is distributed around the world. The phylogenetic relationship of Macropsinae appears to be confused, and the taxonomic status of some genera strongly needs to be verified and discussed. We choose 23 Cicadellidae species (including 22 Macropsinae of ingroup and 1 Idiocerinae of outgroup) as the material and 23 DNA sequences of mt CO Ⅰ gene were obtained, their sequence composition and genetic distance were analyzed, and the phylogenetic trees using the methods of ML and BI were built, the results show that: the content of A+T in the sequences of CO Ⅰ gene was significantly higher than that of G+C; there were statistically significant differences in genetic distance between species, genera and subfamilies; the phylogenetic tree well supports the monophyly of genus Oncopsis and Pedionis, but weakly supports Macropsis and Pediopsoides.
