6th International Congress of DipterologyPhylogeny of Sarcophagid flies based on the comparativemorphology of female postabdomensKurahashi, H.Reference Museum, Department of Medical Entomology, National Institute of InfectiousDiseases, Toyama 1-23-1, Shinjuku-ku, Tokyo 162-8640 JAPANIt has been not easy to identify the females of Sarcophagid flies, althoughthe male genitalia are very useful for identification. However, the malegenitalia do not seem to be good for phylogenetic analysis because they arevery complex in structure and modified among species. The phylogeny ofthe Japanese Sarcophagidae including some Oriental species was analyzedbased on 41 morphological characters by using the UPGMA program. Thestudy material consisted of females collected in copulo with males thatcould be identified or specimens identified by a taxonomic authority.These 41 morphological characters were mainly selected based on groundplans of the calyptrate muscoid female postabdomen. tergites 5-9, sternites5-9, SPAP, SUAP and spermathecae were classified based on their shapes,vestitures, and apparent homologies. Their character states were scored as0: primitive state, 1: intermediate, 2: advanced, 3: more advanced.Among the Asian sarcophagid flies, three big clusters were produced. Thefirst one is the Subfamilies Miltogramminae+Paramacronychinae, and thesecond group was the tribes Raviniini+Protodexiini+Goniophytoini. The3rd cluster was the biggest and most complex, and consists of TribeSarcophagini. The dendrogram of Sarcophagini had 6 main branches andcomprised more than ten small clusters. The first and second groups seemto be more morphologically primitive than Sarcophagini and distinctlyseparated from each other and from the third group.The further detail examination and analysis based on the world widematerials may contribute to discuss the generic taxonomy of tribeSarcophagini.Key Words: phylogeny, Sarcophagidae, comparative morphology, femalepostabdomen143
