First Iranian record of the family Odiniidae (Diptera: Opomyzoidea), including two species new to the Middle East region.

The family Odiniidae is newly reported from Iran through the recent discovery of the species Odinia meijerei Collin, 1952 and Turanodinia graciosa Krivosheina Krivosheina, 1996 in Iran and the Middle East region. The species T. graciosa is here elevated from the rank of subspecies (Turanodinia stackelbergi graciosa Krivosheina Krivosheina, 1996) to species level. This taxonomical change was based on the comparison of the male genitalia of T. graciosa with T. stackelbergi Krivosheina Krivosheina. Images of the habitus and male genitalia of O. meijerei and T. graciosa are provided.
