Determination of phylogenetic position of Pipizini (Diptera : Syrphidae): based on molecular biological and morphological data

Based on the sequence analysis of 5.8S subunit and internal transcribed spa cers (ITS) of ribosomal RNA gene (rDNA), the molecular phylogenetic tree of representative species of Pipizini and three groups of Syrphidae with diff erent feeding habits (seven species belong to six general was constructed. Meanwhile, the phylogenetic tree of tribes (including Pipizini and other 17 tribes of Syrphidae) was constructed using morphological characteristics o f adults and larvae and the number of chromosomes. Both the results show th at the relationship between Pipizini and predatory groups is closer than th at between Pipizini and saprophagous groups. So it is suggested that Pipizi ni be transferred from Milesiinae to Syrphinae.
