Anoplocheylus sinai sp. nov. Bagheri

( Figs. 1–2 )

Female (n=11). Dimensions of holotype (measurements of paratypes in parentheses): length of body (including gnathosoma) 688 (570–710), length of body (excluding gnathosoma) 500 (470–500); width 275 (200–304), length of leg I 425 (363–408), leg II 275 (230–260), leg III 338 (304–341), leg IV 413 (375–400).

Dorsum ( Fig. 1 A). Peritremes present in membrane connecting gnathosoma and idiosoma, entirely chambered (approximately 30 chambers in each side); prodorsal shield with a pair of claviform sensillae (sc1) 60 (58–70) long ( Fig. 1 C) and 5 pairs of simple setae with posterior pair (sc4) very long 90 (95–110) and whip-like; hysterosoma striate and with 16 pairs of setae (c1-h2); setae d3 114 (110–132) and f1 78 (75–80) very long

Venter ( Fig. 1 B). With 20 pairs of subequal setae (excluding pseudanal setae); 2 pairs of setae between coxae I, 3 pairs of aggenital setae and 3 pairs of genital setae present; with 2 pairs of pseudanal setae, ps1 35 (34–42) dorsally and ps2 60 (58–72) ventrally.

Gnathosoma. Palp ( Fig. 1 D) four-segmented; trochanter without setae; femur with 4 simple setae; small genu with 2 setae; tibiotarsus with 1 terminal claw, 2 subapical spurs, 1 falcate seta and 9 simple setae; subcapitulum with 4 pairs of setae, 2 pairs of subcapitular setae and 2 pairs of adoral setae; chelicerae ( Fig. 1 A) separate and with 2 setae, proximal setae 45 (42–45) long

Legs ( Figs. 2 and 1 B). Legs with pretarsus (not shown in 2A) stalked, annulated, bearing a pliable empodium; claws absent; leg femora divided; setal counts of leg segments (solenidia and seta ĸ not included) as follows: Tarsi 21(ω)- 9(ω)-10-10, tibiae 10(φ,ĸ)-5-7-7, genua 7-5-4-4, telofemora 6-4-3-3, basifemora 8-3-3-2, trochanters 1-2-2- 1, coxal fields 4-3-3-2.

Etymology. This species is named in honour of Sina Zare, son of the second author.

Other stages. Unknown.

Type material. Holotype and ten paratype females from soil in apple and blackcherry orchards, Miandoab and Azarshahr, East Azerbaijan province, Iran, 29 September 2010, by Elham Zarei and Mansoureh Ahaniazad. The holotype and one paratype will be deposited in the mite collection of the ARC- Plant Protection Research Institute, Pretoria, South Africa and nine paratypes were deposited in the Collection of the Acarology Laboratory, University of Maragheh, Maragheh, Iran.

Remarks. Anoplocheylus sinai sp. nov. closely resembles A. malayeriensis and A. clavatus in having setae (sc1) claviform, five pairs of simple setae on the prodorsal shield, and d3 and f1 the longest hysterosomal setae. However, it can be easily distinguished from A. clavatus by having claviform sensillae more slender opposed to distinctly broad in A. clavatus . The new species can also be distinguished from A. malayeriensis by: (1) tarsi III and IV with 10 setae vs. 9 setae in A. malayeriensis ; (2) tibiae I with 10 (φ,ĸ) vs. 9 (φ,ĸ) in A. malayeriensis ; (3) telofemura II with 4 setae vs. 3 setae in A. malayeriensis ; and (4) trochanter II with 2 setae vs. 1 setae in A. malayeriensis .
