Cenopalpus khosrowshahii sp. nov.

( Figs. 28–36 )

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 v2 longer than distance v2–v2; most opisthosomal setae slightly shorter and narrower than propodosomal setae, becoming much shorter posteriorly, with e1 and h1 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.

Venter ( Fig. 29 ). Ventral propodosoma and intercoxal area III–IV smooth ( Fig. 29 ); intercoxal area between coxae III–IV smooth, opisthosomal venter with coarse transverse striae anterior to ventral shield and lateral to ventral and genital shields.

Ventral setae attenuate, setae 4a 1.5 times longer than 1a, aggenital setae (ag) 19 (15) almost as long as g1. Ventral, anal and genital shields reticulate ( Fig. 29 ); aggenital setae (ag) almost smooth; anal setae (ps1–2) slightly shorter than genital setae, setae g1 16 (14), g2 13 (11), ps1 14 (9), ps 2 9. Genital and pseudanal setae slightly serrate. Distances: g1–g1 26 (25), g2–g2 43 (40), g1-g2 11 (10).

Gnathosoma ( Figs. 30–32 ). 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. Tarsi I and II with solenidia Iω 13(12), IIω 11(10) ( Figs. 33–34 ). Chaetotaxy as in Fig. 33–36 . Tarsal claws uncinate and the empodia pad-like.

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 .
