6th International Congress of DipterologyMolecular phylogeny of the superfamily Tephritoideareanalyzed with addition of rare taxa includingCtenostylidae, Eurygnathomyia and TachiniscaHan, H.-Y. & K.-E. RoDepartment of Life Science, College of Liberal Arts and sciences, Yonsei University,Gangwon-do 220-710, KoreaThe phylogeny of the superfamily Tephritoidea (Diptera: Muscomorpha)was reanalyzed from three mitochondrial gene fragments (12S, 16S, andCOII) using previously published dataset plus some additional speciesrepresenting various taxa critical but not used in the past mostly because oftheir rarity. These additional taxa include Tanypezidae, Ctenostylidae,Tachinisca, Ortalotrypeta, and Eurygnathomyia. Phylogenetic signalpresent in different gene fragments as well as combinations of genefragments was examined using the minimum evolution method as well asBayesian inference. We have tried to answer the following questions basedon this expanded dataset. (1) Is the Tephritoidea monophyletic? (2) Are thefamilies Tanypezidae and Conopidae closely related to the Tephritoidea?(3) What is the phylogenetic position of the family Ctenostylidae? (4) DoesTachinisca belong to Tephritidae or Pyrgotidae? (5) What’s thephylogenetic position of the genus Eurygnathomyia? Does it deserve itsown family status? (6) Are the important conclusions from the previousstudy still hold when substantial number of species added?Key Words: Diptera, Tephritoidea, 16S rRNA, 12S rRNA, COII∗∗∗∗∗∗∗∗∗∗95
