( Figures 1C, D View Figure 1 , 6A–F View Figure 6 )
Type material
Holotype ♂ ( MMUE), IRAN: Fars Province: Shiraz , 29.6°N, 52.516667°E, 18‒26 May 2000 (Y. M. Marusik) GoogleMaps . Paratypes: 1♂ 4♀ ( ZMMU), 4♀ ( MMUE), same data as for the holotype.
Etymology
The specific epithet refers to the capital of the Achaemenid Empire under Cyrus the Great, which is nowadays an archaeological site approximately 90 km north-east of Shiraz; noun in apposition.
Diagnosis
In the habitus, the new species differs from all of the congeners occurring in the region by lacking a carapace pattern in combination with lacking leg annulations. Its male can be easily distinguished from the congeners occurring in the region by having a tegular bump (Tb), almost equally long longitudinal terminal (Ta) and radical (Ra) apophyses (vs different in length or not elongate), and by having a kind of tooth (Rt) on the tip of radical apophysis. The female of the new species differs from all other species known in the region by having an arch-shaped notch of the plate (Pc), with the plate bearing copulatory openings (vs plate with extension (‘scape̍) bearing copulatory openings).
