Six species, Phaonia erronea (Schnabl, 1887), Phaonia trimaculata (Bouché, 1834), Helina evecta (Harris, 1780), Lispe pectinipes Becker, 1903, Lispocephala mikii (Strobl, 1893) and Thricops bukowskii (Ringdahl 1934) are newly recorded from Iran. One species, Helina irani spec. nov. is described. Based on literature-references and the current investigation a table is provided, listing all 79 muscid species hitherto known from the country. Keywords: Diptera, Muscidae, newly recorded, new species, Iran, list of species Introduction The family of Muscidae is large and very speciose, with a worldwide distribution. Although species have been collected practically in every biogeographic region, the knowledge of the Muscidae is based primarily on the muscid fauna of those few countries, where Muscidae has been investigated more intense. From many large geographical regions, however, only little information on the distribution of Muscidae-species is available. This applies also for some parts of West Asia. For example, when studying unidentified muscid flies, collected in recent years in Iran, no compilation of the species, which are known from Iran, were found in literature. Although in total only 30 specimens, deposited at the collections of the Moravian Museum, Brno, Czech Republic (MM) and the Institute of Biodiversity and Ecosystem Research, Sofia, Bulgaria (IBER) respectively, were investigated, twelve different species belonging to seven genera were identified. Six of the species belonging to the genera Phaonia Robineau-Desvoidy, 1830, Helina Robineau-Desvoidy, 1830, Lispe Latreille, 1796, Lispocephala Pokorny, 1893 and Thricops Rondani, 1856 are new records for Iran and in addition one new species of the genus Helina is described. The localities of the twelve species collected and a list of the 79 species, hitherto reported in literature from Iran, are presented. Materials and Methods For identification of the flies primarily the keys to the Muscidae of the Palaearctic Region by Hennig [1] and additionally the keys to the Muscidae of Central Europe published by Gregor at al. [2, 3] were used. External morphological features of the specimens were examined using a ZEISS Stemi 2000-C stereomicroscope. For the investigation of male terminalia the end of the abdomen was removed and placed in 10% KOH solution for about three hours at room temperature. Later it was washed, transferred to glycerine and dissected. After studying the terminalia were stored in a microvial containing glycerine. The microvial was pinned directly underneath the associated specimen. For illustrations an AxioCam ERc5s camera and for further processing Correspondence Helicon Focus 6 and Adobe Photoshop CS2 were applied.
