The aim of this study was to address the systematic position of the disputed elements in the intrafamilial classification of Syrphidae, namely the monophyly of Eristalinae and the placement of Microdontini and Pipizini, as well as the position of particular genera (Nausigaster, Alipumilio, Spheginobaccha). Sequence data from nuclear 28S rRNA and mitochondrial COI genes in conjunction with larval and adult morphological characters of fifty-one syrphid taxa were analysed using optimization alignment to explore phylogenetic relationships among included taxa. A species of Platypezidae, Agathomyia unicolor, was used as outgroup, and also including one representative (Jassidophaga villosa) of the sister-group of Syrphidae, Pipunculidae. Sensitivity of the data was assessed under six different parameter values. A stability tree summarized the results. Microdontini, including Spheginobaccha, was placed basally, and Pipizini appeared as the sister-group to subfamily Syrphinae. The monophyly of subfamily Eristalinae was supported. The results support at least two independent origins of entomophagy in syrphids, and frequent shifts between larval feeding habitats within the saprophagous eristalines.10a[Phylogeny / Intrafamilial relationships / Revaluation using combined10aanalysis of molecular & morphological characters].10afeeding habits / ] [Molecular genetics / Nuclear 28S rRNA &10amitochondrial COI gene sequences / ] [Evolutionary adaptation / / ]10aPipunculidae10aSyrphidae [General morphology / / ] [Diet / Entomophagy & larval1 aStåhls, Gunilla1 aHippa, Heikki1 aRotheray, Graham1 aMuona, Jyrki1 aGilbert, Francis  u<u><Go to ISI>://ZOOR14002008264</u>
