A field survey of the bee fauna was conducted in the north of Iran during ۲۰۰۹ to ۲۰۱۵. Special concern was given to the tribe Ceratinini (Hymenoptera; Apidae). Ten species of the genus Ceratina were collected and identified in the present study. Three species are recorded for the first time from Iran, including Ceratina (Euceratina) chrysomalla Gerstaecker ۱۸۶۹, Ceratina (Euceratina) cyanea (Kirby, ۱۸۰۲) and Ceratina (Euceratina) gravidula Gerstaecker, ۱۸۶۹. An updated checklist of Iranian Ceratinini with short description and figures of newly recorded species are provided. The host plants and distribution of each species are also given.
