Diagnosis. Rostral shield with 2 medial lobes, 2 submedial lobes and 2 small lobes laterally; propodosoma and opisthosoma with irregular, large reticulations medially and transverse areolae sculpturing laterally; opisthosomal pores absent; propodosomal setae narrowly lanceolate, serrate, setae v2 longer than distance v2–v2; opisthosomal setae, except c1 and d1, shorter than propodosomal setae, becoming very short posteriorly, narrowly to broadly lanceolate. Intercoxal area between coxae III–IV smooth, opisthosomal venter with irregular areolae behind coxae IV, smooth medially. Solenidia Iω 13–16, IIω 14.

Dorsum ( Fig. 37 View FIGURES 37 – 41 ). Rostral shield with 2 medial lobes, 2 submedial lobes and 2 small lateral lobes. Dorsal sculpturing with irregular, large reticulations medially and transverse areolae laterally; pores absent ( Fig. 37 View FIGURES 37 – 41 ). Dorsal setae narrowly to broadly lanceolate; v2 longer than distance v2–v2; opisthosomal setae c1 and d1 longer than others. Lengths of dorsal setae as follows (measurements of paratype in parentheses): v2 40 (45), sc1 37 (42), sc2 26 (30), c1 34 (42), c 2 22 (29), c3 24 (25), d1 36 (38), d3 19 (20), e1 16 (13), e3 19 (18), f2 15 (15), f3 14 (12), h1 7 (7), h2 10 (8); distances between dorsal setae; v2–v2 30 (36), v2 –sc1 22 (23), sc1–sc1 68 (74), sc2–sc2 103 (112), sc1 – sc2 31 (30), c1–c1 42 (48), c1–c2 31 (34), c2–c3 7 (8), c2–c2 103 (119), c3–c3 119 (129), c1–d1 35 (38), c3–d3 35 (35), d1–d1 43 (45), d1–d3 34 (40), d3–d3 110 (124), d1– e 1 43 (47), e1– e 1 21 (27), e1– e 3 44 (45), e3–e3 105 (114), e3–f2 27 (26), f2–f2 92 (100), f2–f3 23 (25), f3–f3 73 (75), f3–h2 24 (21), h1–h1 14 (21), h1–h2 14 (14), h2–h2 41 (47), e1–h1 57 (58), d3– e 3 28 (35).
Venter ( Fig. 38 View FIGURES 37 – 41 ). Intercoxal area between coxae III–IV smooth, opisthosomal venter with irregular areolae sculpturing anteriorly, becoming smooth medially, and coarse transverse striae anterior to ventral shield ( Fig. 38 View FIGURES 37 – 41 ). Length of setae la 65 (69), 1b 23 (28), 1c 23 (27), 2b 28 (24), 2c 25 (24), 3a (16), 3b 14 (17), 4a 83 (85), and 4b 18 (17). Setae 1a shorter than 4a and 3.8 times longer than aggenital setae (ag) 17 (17). Ventral and genital shields with incomplete areolation ( Fig. 38 View FIGURES 37 – 41 ); aggenital setae (ag) almost smooth and longer than genital setae (g1–2); anal setae (ps1–2) almost as long as genital setae, setae g1 11 (10), g2 9 (10), ps1 9 (13), ps2 8 (8). Genital and pseudanal setae smooth. Distances: g1–g1 25 (26), g2–g2 39 (42), g1–g2 8 (9).
Gnathosoma ( Figs. 39–41 View FIGURES 37 – 41 ). Rostrum reaching end of femur I ( Fig. 39 View FIGURES 37 – 41 ); 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. 41 View FIGURES 37 – 41 ). Subcapitulum with seta m 12 (11), distance m–m 10(10). Chelicerae as in Fig. 40 View FIGURES 37 – 41 .
Legs ( Figs.42–45 View FIGURES 42 – 45 ). Legs much shorter than body, about 1/3 of idiosomal length. Setal formulae of leg segments as follows (including the specialized sensory setae such as solenidia in parentheses): 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. Tarsus I and II with solenidia Iω 13 (16), IIω 14 (14) ( Figs. 42–43 View FIGURES 42 – 45 ).
Male and immature stages— Unknown.
Type material. Holotype female and 1 female paratype collected from oak trees, Quercus castaneifolia C.A.Mey. (Fagaceae) , IRAN: Lorestan Province, Robat namaki, 33°33ʹN, 48°26ʹE, 1800 m a.s.l, 7 August 2011, coll. M. Khanjani.
Type deposition. Holotype female—CALBS; 1 female paratype—QMA.
Etymology. The species is named after its host, the oak trees genus, Quercus .
Remarks. Cenopalpus quercusi resembles C. abaii Khosrowshahi and Arbabi, 1997 in having rostral shield with two bicuspid lobes medially and two small lobes laterally, propodosomal setae broadly lanceolate and v2 longer than distances of v2–v2 and v2–sc1. However C. quercusi differs from the latter in: rostrum extends to distal end of femur I (extends beyond end of femur I in C. abaii ); opisthosoma medially with irregular large reticulations in new species (small reticulations in C. abaii ); seta d1 36–38 in the new species (d 1 21–26); and the ratios d1 / d1–d1 0.83 (0.84) instead of 0.63–0.66 in C. abaii , sc1 / sc1–sc2 1.23 (1.35) instead of 0.86–0.97 in C. abaii , c1 / c1–c1 0.88 (0.80) versus 0.57–0.61 in C. abaii and e3 / e3–f2 0.70 (0.65) instead of 0.36–0.50 in C. abaii .
