Diagnosis. Integument heavily sclerotized and purple in life; prodorsum with striae continuous; setae vi and sce not longitudinally aligned, setae sce clearly further apart than vi, forming a wide-based trapezium; trochanter I with 1 seta; prodorsal setae vi, ve and sci not longitudinally aligned, sci almost longitudinal in line with setae vi; trichobothrium present on each of tibiae I, IV and tarsus III.

Male (n = 5). Color purple in life. Total body length (including gnathosoma from apex of capitulum to posterior margin of idiosoma) 1091 (1033–1143), body length (excluding gnathosoma) 615 (573–655); width 399 (375–416).

Dorsum ( Fig. 1 ). Central region of prodorsum (between setae vi and sci) with continuous longitudinal striae; prodorsum with five eyes, diameters of unpaired median eye 10 (9–10), anterior lateral eye 17 (15–17), and posterior lateral eye 8 (8–9), two lateral eyes separated by distance approximately 3.6 (3.6–4.1) times diameters of anterior lateral eyes, with oblique and irregular striae between each pair; unpaired median eye anterior to seta vi. Transverse fold between setae sci and c 1 in holotype ( Fig. 1 ). All dorsal setae finely serrated, long, each pair clearly reaching to bases of subsequent pair. Dorsum of hysterosoma with fine, continuous, transverse striae, except striae obliquely longitudinal between setae c1 and c2; sce longest and h1 shortest dorsal setae; hysterosomal region with three cupules (ia, im and ip) at level of setae d, e and f1 ( Fig. 1 ).

Gnathosoma ( Fig. 2 ). Capitulum 238 (230–255) long, width at base 166 (116–135); base of gnathosoma with transverse striae but distally with longitudinal striae; palp five-segmented, palp tibiotarsus with three setae + one solenidion + two long terminal setae, DES and VES 353 (352–363) and 278 (268–295), respectively; genu with four setae; telofemur with one seta; basifemur with seven setae [proximal setae longer than rest, 48 (46–55)]; trochanter without setae; Measurements of palp segments as follows: trochanter 15 (13–20), basifemur 226 (218–238), telofemur 40 (35–45), genu 24 (20–22), tibiotarsus 70 (68–70).

Palp coxa with one elcp seta 4 long ( Fig. 2 ).

Venter ( Figs. 3–4 ). Striae between coxae I–II and III–IV longitudinal and between coxae II–III transverse. Aggenital region with seven pairs of setae (ag1–7) and genital valves each with nine setae (g1–9), with anterior three pairs (g1–3) longer than others ( Figs. 3–4 ); anal region with three pairs of setae (ps1–3), smooth: ps1 42 (38–45), ps2 36 (33–34) and ps3 43 (37–43) long and at level of seta ps3 with one pair of cupules (ih); one unpaired seta between coxae IV ( Figs. 3–4 ).

Genitalia ( Fig. 5 ). Amphioid sclerite with nine pairs of setae and laminated gland flower-shaped.

Female: unknown.

Remarks. Cyta leiliae sp. nov. closely resembles C. coerulipes ( Dugès, 1834) in having heavily sclerotized (dark), purple integument and tibiae I, and IV and tarsus III each with a trichobothrium. However, it differs by having: 1) propodosomal striae continuous in C. leiliae but sparsely broken in C. coerulipes ; 2) trochanter I with one seta instead of two; 3) tarsi II with 27ts, 1 w, 2pe, 1 e in new species opposed to 19–21ts, 2 w; 4) tarsi III with 24ts in C. leiliae but 20ts in C. coerulipes ; 5) genu I with three solenidia in C. leiliae but two solenidia in C. coerulipes .

Etymology. This species is named in honour of Ms. Leili Eghbalian, daughter of the senior author.

Type material. The holotype and four paratype males were collected from soil and litter under grass and oak trees, Quercus brantii Lindl , ( Fagaceae ),“Sirvan river bank”, located in Palangan village, Kurdistan Province, Iran, (35° 03.7' N, 46° 35.97' E, a.s.l. 864 m), 14.IV.2013, by Amir Hossein Eghbalian. The holotype and three paratype females are deposited in the mite Collection of the Acarology Laboratory, University of Bu–Ali Sina, Hamedan, Iran. One paratype female slide will be deposited in the National Collection of Arachnida, Plant Protection Research Institute, Pretoria, South Africa.
