( Figs. 1–9 View FIGURES 1 – 5 View FIGURES 6 – 9 )

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 View FIGURES 1 – 5 ).

Transverse fold between setae sci and c 1 in holotype ( Fig. 1 View FIGURES 1 – 5 ). 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 c 1 and c 2; sce longest and h 1 shortest dorsal setae; hysterosomal region with three cupules (ia, im and ip) at level of setae d, e and f 1 ( Fig. 1 View FIGURES 1 – 5 ).

Ratio vi / sce 0.76 (0.71–0.76), vi / vi–vi 3.6 (3.3–3.4); sce / sce–sce 1.3 (1.36–1.4).

Gnathosoma ( Fig. 2 View FIGURES 1 – 5 ). 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). Subcapitulum with two pairs of long ventral setae (vh 1 and vh 2), proximal pair (vh 1) 80 (73–85), almost twice length of distal pair (vh 2) 51 (45–48); two pairs of short adoral setae near tip of subcapitulum, avs 21 (18–24) and ad 19 (20–22). Chelicerae with two dorsal setae (ch 1–2), proximal setae 95 (70–80), almost twice length of distal setae, 42 (43–48), fixed digit with setae ch 1–2; movable chelae with one tooth and fixed digit with two teeth. Palp coxa with one elcp seta 4 long ( Fig. 2 View FIGURES 1 – 5 ).

Venter ( Figs. 3–4 View FIGURES 1 – 5 ). Striae between coxae I–II and III–IV longitudinal and between coxae II–III transverse. Aggenital region with seven pairs of setae (ag 1–7) and genital valves each with nine setae (g 1–9), with anterior three pairs (g 1–3) longer than others ( Figs. 3–4 View FIGURES 1 – 5 ); anal region with three pairs of setae (ps 1–3), smooth: ps 1 42 (38–45), ps 2 36 (33–34) and ps 3 43 (37–43) long and at level of seta ps 3 with one pair of cupules (ih); one unpaired seta between coxae IV ( Figs. 3–4 View FIGURES 1 – 5 ).

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 27 ts, 1 w, 2 pe, 1 e in new species opposed to 19–21 ts, 2 w; 4) tarsi III with 24 ts in C. leiliae but 20 ts 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.
