Two seed wasps genera, Bruchophagus Ashmead and Systole Walker (Hymenoptera: Eurytomidae) of Iran were reviewed. Host plants and distribution data in Iran are summarized for the species known from Iran including some new biological data. One new species, namely Systole longigaster Lotfalizadeh sp. nov., is described based on recently collected material. Discriminating characters of this are discussed. Illustrations are provided to distinguish the new species and finally its diagnostic characters are discussed. Bruchophagus platypterus (Walker), B. smirnoviae Nikolskaya, B. verbasci (Erdös) and Systole besaparica Stojanova are recorded for the first time in Iran.
