(Figs. 19–27)
Diagnosis. Rostral shield with 2 broad lobes medially (submedial lobes obsolete) and 2 small lobes laterally; propodosoma and opisthosoma with polygonal reticulations medially and irregular areolae sculpturing laterally; opisthosomal pores absent; propodosomal setae broadly lanceolate, serrate, setae v2 length just over one half of distance between v2–v2; anterior opisthosomal setae about as long as propodosomal setae, becoming shorter posteriorly; opisthosomal setae serrate and broadly lanceolate, except h1 and h2 narrowly lanceolate and much shorter than other dorsal setae. Intercoxal area between coxae III–IV smooth, opisthosomal venter with irregular reticulations behind coxae IV, smooth medially. Solenidia Iω 14–16, IIω 14–18.
Description. Female (Holotype). Color in life red. Idiosoma oval. Length of body (excluding gnathosoma) 357 (345–347 in 2 paratypes); (including gnathosoma) 425 (406–415); width 186 (170–190); length of leg I 180 (174–178); leg II 187 (169–176); leg III 146 (132–138), leg IV 158 (145–156).
Dorsum (Fig. 19). Rostral shield with 2 broad medial lobes (submedial lobes obsolete) and 2 lateral lobes (Fig. 19).

Length of seta v2 0.7 times distance between v2–v2; seta v2 shorter than distance between setae v2 –sc1; lengths of dorsal setae as follows: v2 26 (23–28), sc1 23 (21–26), sc2 18 (21–26), c1 29 (24–26), c 2 25 (21–26), c 3 24 (20–23), d1 23 (19–22), d3 19 (20–21), e1 19 (17– 21), e3 20 (18–21), f2 21 (16–19), f3 17 (14–17) h1 9 (7–9), h2 12 (10–12); distances between dorsal setae: v2–v2 37 (31–34), v2 –sc1 31 (30–33), sc1–sc1 86 (84–87), sc2–sc2 139 (137–140), sc1–sc2 40 (38–42), c1–c1 55 (54–57), c1–c2 40 (34–42), c2–c3 14 (10–15), c3–c3 156 (149–151), c1–d1 41 (39–41), f3–f3 103 (97–107), d1–d1 42 (40–41), d1–d3 60 (56–62), d3–d3 159 (155–158), d1– e 1 62 (58–62), e1– e 1 32 (28–30), e1– e 3 64 (58–63), e3–e3 156 (147–149), f2–f2 121 (126–127), f3–f3 104 (91–100), f2–f3 32 (27–34), f3–h2 30 (20–28), h1–h1 25 (29–31), h1–h2 19 (15–18), h2–h2 60 (64– 60), e1–h1 72 (68–73), d3– e 3 42 (39–46), c3–d3 43 (40–42).
Venter (Fig. 20). Propodosomal and intercoxal area between coxae III–IV smooth; posterior to coxae IV reticulate laterally, fading to smooth medially; region anterior to ventral shield with coarse transverse striae. Length of setae la 95 (94–103), 1b 48 (46–52), 1c 35 (32–33), 2b 56 (48–56), 2c 27 (22–28), 3a 28 (24–26), 3b 25 (21–23), 4a 86 (89–93), and 4b 31 (22–26). Ventral setae fine, setae 1a about 4 times longer than aggenital setae (ag) 22 (18–19). Ventral shield, genital shield and anal shield reticulate (Fig. 20); aggenital setae (ag) serrate and longer than genital setae (g1–2); inner pair (g1) posterior to outer pair (g2); anal setae (ps1-2) about as long as genital setae, setae g1 13 (13–15), g2 10 (10–11), ps1 13 (9–14), ps2 10 (9–12). Distances: ag–ag 26 (26–27), g1–g1 26 (28–30), g2– g2 44 (38–46), g1–g2 11 (10–12).
Gnathosoma (Figs. 21–23). Rostrum long and extending to end of tibia I (Fig. 21); palp 4-segmented, with 1 solenidion and 2 eupathidia; palp genu-tibia with 2 setae; palp femur with 1 dorsal barbed seta (Fig. 23). Subcapitulum with seta m 20 (15–20), distance m–m 9 (8) (Fig. 21). Chelicerae depicted in Fig. 22.
Legs (Figs. 24–27): Legs shorter than body. 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. Tarsus I and II with solenidia Iω 16 (14–16), IIω 18 (14–16) (Figs. 24–25). Femur I and II with 2 broadly lanceolate setae. Tarsal claws uncinate and empodia pad-like.
Male and immature stages. Unknown.
Type material. Holotype female and 2 female paratypes from plum leaf, Prunus domestica L. (Rosaceae), IRAN: Hamedan Province, Hamedan, 34º45ʹN, 48º31ʹE, 1991 m a. s. l, 8 September 2010, coll. M. Khanjani.
Type deposition. Holotype female and 1 female paratype – CALBS; 1 female paratype – QMA.
Etymology. The species is named for its host genus, Prunus.
Remarks. Cenopalpus prunusi resembles C. picitilis Chaudhri, 1971 in having both dorsal shields with large cells of reticulation medially, a long rostrum reaching the end of tibia I, and a rostral shield with two medial lobes. However, the new species differs by having: palp tarsus with one solenidion and two eupathidia (one solenidion only in C. picitilis), propodosomal setae long, v2 (26), sc1 (23), sc2 (18) [v2 (7), sc1 (8), sc2 (11) in C. picitilis], and genua 3-3-1-0 vs. 2-2-1- 1 in C. picitilis.
