Paratypes: 3♀ ( ZMMU), 3♀ ( MMUE), same data as for the holotype; 2♀ ( ZMUT), Alborz Province: Sardor area , 10 km N of Karaj, 30.833333°N, 51.083333°E, 13 June 2000 (Y.M. Marusik) GoogleMaps .

Etymology

This species is named after Darius I, who is more commonly known as Darius the Great. He was the third King of Kings of the Achaemenid Empire and reigned from 522 BCE until his death in 486 BCE. During his rule, the empire reached its territorial peak.

Diagnosis

In the shape of the epigyne, the new species resembles O. latiscapus Wunderlich, 1992 , known only from Tenerife. Both species have a wide ‘scape̍ (Sc), a character unknown in the congeners. The new species can be distinguished by the heavily sclerotised tip of scape (vs not sclerotised) and by having many arched wrinkles in the anterior half and three posteriorly to the ‘scape̍ (vs numerous straight wrinkles posteriorly from the ‘scape̍), and a few straight wrinkles anteriorly from the ‘scape̍ (compare Figure 2A–C View Figure 2 and Wunderlich 1992, fig. 283). The vulva of O. latiscapus has never been illustrated, and therefore cannot be compared with that of the new species.

Description
