Cenopalpus saryabiensis Akbar and Chaudhri, 1958: 270 , figs. 1(A–D); Khosrowshahi and Arbabi 1997: 9, figs. 5–6.

Diagnosis. Rostral shield poorly developed, with small slightly notched medial lobes only; propodosoma and opisthosoma mostly striate, becoming longitudinally areolae posteriorly; opisthosomal pores absent; opisthosoma divided into metapodosomal and opisthosomal regions by transverse band of coarse striae; propodosomal setae lanceolate, serrate, setae v2 shorter than distance v2–v2; opisthosomal setae shorter than propodosomal setae, marginal setae lanceolate, serrate, sublateral and central setae slender, sparsely barbed. Intercoxal area between coxae III–IV smooth, opisthosomal venter with coarse striae behind coxae IV. Solenidia Iω 30–32, IIω 25–28.

Re-description. Female (n = 2). Color in life reddish to orange. Idiosoma oval. Length of body (excluding gnathosoma) 293–322; (including gnathosoma) 334–367; width 160–155; length of leg I 128–144; leg II 115–129; leg III 110–113; leg IV 116–119.

Dorsum ( Fig. 46 ). Rostral shield poorly developed, with slightly notched medial lobes only ( Fig. 46 ). Propodosoma and metapodosoma transverse striate and opisthosoma longitudinally striate-areolae; sejugal furrow comprises broken transverse striae; pores absent ( Fig. 46 ). Propodosomal and lateral setae lanceolate, sublateral and central setae short and sparsely barbed; v2 shorter than distance between v2–v2, lengths of dorsal setae as follows: v 2 13–20, sc 1 12–17, sc 2 18–22, c 1 13–16, c 2 10–13, c 3 10–15, d 1 9–10, d 3 13–16, e1 7 –9, e 3 16 –20, f 2 16–19, f 3 13–18, h 1 13–14, h 2 16–20; distances between dorsal setae; v2–v2 33 – 35, v2 –sc1 38–41, sc1–sc1 100–104, sc2–sc2 132–138, sc1– sc2

22–26, c1–c1 57–60, c1–c 2 29–33, c2–c 3 11–15, c2–c2 118–120, c3–c3 141–147, c1–d1 40–45, c3–d3 53–56, d1–d1 49–52, d1–d3 46–51, d3–d3 145–147, d1– e 1 63–72, e1– e 1 30–33, e1– e 3 62–63, e3–e3 144–147, e3–f 2 28–31, f2–f2 137–140, f2–f 3 21–25, f3–f3 115–117, f3–h 2 25–30, h1–h 1 29–33, h1–h2 32–33, h2–h2 85–86, e1–h1 64–69, d3– e 3 37–45.

Venter ( Fig. 47 ). Coxisternal areas between I–II with few transverse striae and area between III–IV smooth; area between 4a and ag with coarse transverse striae ( Fig. 47 ). Length of setae la 63–67, 1 b 14–17, 1 c 13–14, 2 b 11–13, 2 c 17–17, 3 a 13–16, 3 b 8–12, 4 a 55–56, and 4b 10–12. Ventral setae 1a 4.8 times longer than 3a and aggenital setae (ag) 11–12. Ventral and genital shields transversely areolae ( Fig. 47 ); aggenital setae (ag) shorter than genital setae (g1–2); inner pair (g1) slightly posterior to outer pair (g2); anal setae (ps1–2) shorter than genital setae, setae g 1 17–19, g 2 22–25, ps 1 9–11, ps 2 13–17. Distances between aggenital and genital setae as follows: ag– ag 35–35, g1–g1 37–38, g2–g2 51–53, g1–g2 8–9.

Gnathosoma ( Figs. 48–50 ). Rostrum extending to end of femur I ( Fig. 47 ); palp 4 segmented, palp tarsus with a solenidion and 2 eupathidia; palp genu-tibia with 1 seta, palp femur with 1 dorsal seta ( Fig. 50 ). Subcapitulum with seta m 11–12, distance m–m 9–11. Chelicerae as in Fig. 49 .

Legs ( Figs. 51–54 ). Legs rather short, 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. Dorsal setae distinctly serrated ( Figs. 51–54 ). Tarsus I and II with solenidia Iω 30–32, IIω 25–28 ( Figs. 51–52 ). Tarsal claws uncinate and the empodia pad-like.

Male and immature stages. Unknown.

Type material. Pine tree leaves, Pinus sp. (Pinnaceae), PAKISTAN: Balochistan province, Quetta, 1680 m a. s. l., 20 June 1981, coll. S. Akbar & W.M. Chaudhri and deposited at ALRDEFP.

Other material examined. Two females collected from pine tree leaves, Pinus abies (L.) (Pinnaceae), IRAN: Alborz province, Karaj, 35°45ʹN, 50°58ʹE, 1324 m a. s. l., 28 June 1986, coll. M. Khosrowshahi. Deposited at CALBS.

Remarks. The Iranian specimens exhibit most characters of Akbar and Chaudhri’s (1985) description, except for: area between 4a and ag with transverse striae in Iranian specimens instead of smooth; palp tarsal setae shorter than the Pakistani specimens; area between setae h1 and h2 almost smooth instead of striate; and coxisternal area I– IV with few striae laterally whereas smooth. We consider most of these characters minor, except for the striation of the ventral opisthosoma. However, with only 2 specimens and without examining type specimens, we think it better to consider them conspecific pending further study.
