Type material.

Holotype ♂ (ZMUT), Iran: Tehran Province: Tehran, 35°45'N, 51°24'E, 04.2014 (A. Zamani). Paratypes: 1♂1♀ (ZMUT), Tehran, 35°42'N, 51°25'E, 03.2014 (A.H. Bakhtiari).

Etymology.

The specific epithet is a noun in apposition, referring to an ancient tribe dwelling in the Iranian plateau.

Diagnosis.

The male of this species differs from those of the other species of the Dysdera aculeata group occurring in Iran by the strong dorsal incision between tegulum and psembolus, and the posterior apophysis bent on right angle (vs. no or small incision, and posterior apophysis not bent on right angle); the most similar species is D. mikhailovi Fomichev & Marusik, 2021 from Tajikistan, from which the new species differs by having a dorsal incision between tegulum and psembolus, the parallel dorsal sides of tegulum and psembolus (vs. dorsal margin of psembolus inclined), and smaller retrolateral crest angled at distal 1/3 of psembolus (vs. larger and angled at mid-part). The female of D. sagartia sp. nov. differs from those of its congeners occurring in Iran by having an arched anterior margin of receptacle in combination with a lack of anterior angles (vs. species with arched receptacle have anterior angles), and the almost semiround dorsal arch (vs. trapezoidal).
