Figs 25A-C, 26A-D

Type material.

Holotype ♂ (ZMUT), Iran: Mazandaran Province: Polur, surroundings of Mount Damavand, 35°50'N, 52°03'E, 10.2015 (A. Zamani).

Etymology.

The specific epithet is an adjective, referring to the type locality of the species.

Diagnosis.

The male of the new species is most similar to that of D. concinna L. Koch, 1878 from Azerbaijan, but differs by longer bulb (i.e., bulb length/tegulum width =3.1, vs. 2.7), relatively shorter median crest, and longer stylus (cf. Fig. 26A and Dunin 1982: fig. B). Dysdera damavandica sp. nov. is also similar to D. tapuria sp. nov. but differs by the median crest higher than wide (vs. wider than high), relatively longer stylus (cf. Fig. 26A and Fig. 30A) and posterior apophysis located at distal half of the bulb (vs. located at mid-part).
