Rostrum extends to end of femur I (Fig. 30); palp 4-segmented, palp tarsus with a solenidion and 2 eupathidia distally; palp genu-tibia with 2 setae, palp femur with 1 dorsal seta (Fig. 32). Subcapitulum with seta m 11 (16), distance m–m 11 (12) (Fig. 30). Chelicerae as in Fig. 31.

Legs (Figs. 33–36). Legs much shorter than body, about 1/3 length of the idiosoma. Setal formulae of leg segments as follows: coxae 2-2-1-1; trochanters 1-1-2-1; femora 4-4-2-1; genua 3-3-1-0; tibiae 5-5-3-3; tarsi 9(1ω) - 9(1ω)-5-5.

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°48ʹN, 47°29ʹE, 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 e1 narrowly serrated (broadly lanceolate in C. pennatisetis); tarsi 9(1ω)-9(1ω)-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 c1 / c1-c1 = 0.52 vs. 0.82 in C. pennatisetis .
