Type material.

Holotype ♂ (ZMUT), Iran: Golestan Province: Shast Kalateh, 36°45'N, 54°21'E, 2017 (R. Rafiei-Jahed). Paratypes: 7♂5♀ (ZMUT), same data as the holotype; 1♂ (ZMUT), Mazandaran Province: Polur, 35°50'N, 52°03'E, 10.2015 (A. Zamani); 1♂ (MHNG), Kiyasar, 36°14'N, 53°33'E, 1500 m, 11.07.1975 (A. Senglet).

Etymology.

The specific epithet is an adjective, referring to the historical region of the Middle East, located in eastern Mesopotamia, which is now Iran.

Diagnosis.

The male of this species differs from those of the other species of the Dysdera aculeata group occurring in Iran by the extremely long bulb (especially psembolus, i.e., twice longer than tegulum), and by the tegulum with posterior margin 1.3 × longer than anterior margin (vs. equal or shorter in length). The female of D. persica sp. nov. differs from those of its congeners by having the broadest dorsal arch, bearing almost angled anterior corners (vs. rounded).
