In this study, nine species of the tribe Eucerini (Hymenoptera: Apidae) are recorded from Iran for the first time, based on 1462 specimens deposited in the Iranian Museum of Pollinator Insects at Yasouj University (IPIM-YU). The study draws on a collection of 5807 Eucerini specimens collected between 2006 and 2024, of which 1462 specimens were examined for species-level identification and confirmation of distributional records. Detailed specimen data, including the number of specimens, collection localities, geographic coordinates, and distribution maps for Iran, are provided, along with global distribution information where available. The species newly recorded from Iran are Eucera albofasciata Friese, E. brevitarsis Risch, E. hungarica Friese, E. interrupta Baer, E. latipes Risch, E. monticola Risch, E. seminuda Brullé, E. serraticornis Risch, and E. sociabilis Smith. With these new records, the number of Eucerini species known from Iran increases to 70. Voucher specimens are available for 50 species, whereas the remaining species are included based solely on published records. All Eucerini species recorded from Iran have Palaearctic distributions. A distribution map of the recorded species and an overview of species richness among the genera known from Iran are also presented.
