摘　　要：The flies of genus Glossina (Diptera: Glossinidae) are an important vector of African trypanosomiases which cause diseases in humans and animals. The ribosomal DNA Internal Transcribed Spacer-2 (ITS-2) region sequences from different Glossina species were PCR-amplified and analyzed in order to construct a molecular phylogeny for genus Glossina. Trees generated by parsimony confirmed the monophyletic taxonomic placement of genus Glossina where fusca group species formed the deepest branch followed by morsitans and palpalis groups, respectively. The placement of Glossina austeni by both the traditional morphological and biochemical criteria has been controversial. Results presented here, based on ITS-2 locus sequence analysis, suggest that Glossina austeni can be placed into a separate subgenerus which forms a sister-group relationship with the morsitans group species.The flies of genus Glossina (Diptera: Glossinidae) are an important vector of African trypanosomiases which cause diseases in humans and animals.
