Abstract
The species of Notanisus Walker (Hymenoptera: Pteromalidae: Cleonyminae) from Iran were revised. Four Palaearctic species are recognized: N. clavatus Bouček, N. oulmesiensis (Delucchi), N. vanharteni Gibson and N. versicolor Walker; including one species with macropterous male and the rests with macropterous females. Of which, N. oulmesiensis and N. versicolor are new records for Iran. The species are briefly described based on available materials, illustrated through macrophotography, and their distributions in Iran was mapped.
