Phytogeny of genusGlossina (Diptera:Glossinidae) according to ITS2 sequences.
The flies of genusGlossina (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 differentGlossina species were PCR-amplified and analyzed in order to construct a molecular phylogeny for genusGlossina. Trees generated by parsimony confirmed the monophyletic taxonomic placement of genusGlossina wherefusca group species formed the deepest branch followed bymorsitans andpalpalis groups, respectively. The placement ofGlossina austeni by both the traditional morphological and biochemical criteria has been controversial. Results presented here, based on ITS-2 locus sequence analysis, suggest thatGlossina austeni can be placed into a separate subgenerus which forms a sister-group relationship with themorsitans group species.
