Diagnosis. Rostral shield with 2 lobes medially (submedial lobes obsolete) and 2 small lobes laterally; propodosoma with irregularly areolae sculpturing; opisthosoma with incomplete transverse-oblique reticulations laterally and variable areolae-reticulate region medially, becoming regularly reticulated posteriorly; opisthosomal pores absent; propodosomal setae broadly lanceolate, serrate, setae v 2 longer than distance v 2 –v 2; most opisthosomal setae slightly shorter and narrower than propodosomal setae, becoming much shorter posteriorly, with e 1 and h 1 narrowly lanceolate and shorter than other dorsal setae. Intercoxal area between coxae III–IV smooth, opisthosomal venter with areolae sculpturing behind coxae IV, smooth medially. Solenidia Iω 12–13, IIω 10–11.

Male and immature stages. Unknown.

Material examined. Holotype female and 1 female paratype collected on Pagoda trees, Sophora alopecuroides  L. ( Fabaceae  ), IRAN: Hamedan Province, Hamedan, 35 ° 48 ʹN, 47 ° 29 ʹE, 1810 m a. s. l, 23 October 2008, coll. M. Khanjani.

Type deposition. Holotype female—QMA; 1 female paratype—CALBS

Etymology. This species is named in honor of Dr. Mahdi Khosrowshahi, who kindly lent us type specimens from his private collection.

Remarks. The new species is similar to C. pennatisetis ( Wainstein, 1958)  in having the same rostral shield, form of dorsal setae and long propodosomal setae, extending to the bases of setae in the next row. However, differs from it in: medial propodosomal shield smooth (reticulated regularly in C. pennatisetis  ); opisthosoma without pores (one pair of pores in C. pennatisetis  ); setae e 1 narrowly serrated (broadly lanceolate in C. pennatisetis  ); tarsi 9 (1 ω)- 9 (1 ω)- 5 - 5 (7 - 7 - 5 - 5 in C. pennatisetis  , but this may be an oversight); opisthodorsum reticulated irregularly (reticulated regularly in C. pennatisetis  ) and ratio c 1 / c 1 -c 1 = 0.52 vs. 0.82 in C. pennatisetis  .
