Review of the Iranian species of the genus Pipizella Rondani, ۱۸۵۶ (Diptera, Syrphidae), with description of a new species from Iran and Azerbaijan

The species of the genus Pipizella Rondani, ۱۸۵۶, from Iran are reviewed. In this review, new records of three species are presented: Pipizella baybaurtica Claussen & Hayat, ۱۹۹۷, P. ochreobasalis van Steenis & Lucas ۲۰۱۱, and P. orientalis van Steenis & Lucas ۲۰۱۱. One new species, Pipizella barbata Mortelmans & van Steenis sp. nov., is described based on type specimens collected from Iran and Azerbaijan. In total, nine species are mentioned to occur in Iran, however some identifications might concern other species for which no material was available for this study. Therefore, the correct number of Iranian species of the genus Pipizella is not clear, but in this study, we present seven confirmed species. Photographs of the new species, illustrations of its male terminalia, as well as an identification key to the known Iranian species, are provided. Finally, a discussion about the Iranian fauna and the possible number of Pipizella species is given.
