Distribution. Empidideicus (Cyrtoides) reemeri sp. nov. was collected only in the Abazar village of Qazvin city in the north of Iran.

Remark. Empidideicus (Cyrtoides) reemeri sp. nov. is easily separated from the other species of the subgenus Cyrtoides in Iran, Empidideicus (Cyrtoides) primitus sp. nov., by the completely black occiput. For the separation of all known species of the subgenus Cyrtoides in the World, the key below was prepared.
