Paratypes, same date and locality as holotype, 1 Ψ, 5 ɗ, 4 DN; 14 June 2004,Yomra district, Fındıklı village, (40°86ˏ N, 39°95ˏ) extremly wet weeds and litter, 4 Ψ, 9 ɗ, 4 DN, 750 m a.s.l.

Female (Holotype). Dorsum ( Fig. 1 View FIGURE 1 ). Idiosoma subcircular, dorso-ventrally flattened, 615 µm long and 490 µm wide, well sclerotised and yellow-brown in colour. Dorsal plate entire, surface covered with small circular markings. Plate surrounded by an entire marginal plate. Marginal plate smooth, not ornamented, and bearing 12 pairs of smooth, lanceolate setae. Dorsal plate with 33–35 pairs of relatively long lanceolate setae with fine spicles in proximal half, and whip-like in distal half. All setae long enough to pass insertion of following seta. Posterior end of dorsum lacking circular ornamentation.

Ven te r ( Fig. 2 View FIGURE 2 ). Surface of sternal plate ornamented with small circles. Sternal setae st1-st5 straight, short and simple. Sternal setae st1 inserted level with coxae II, close to anterior end of epigynium; st2-st5 lateral to genital aperture, each accompanied by a circular pore. Genital plate 67 µm long and 45 µm wide. Surface of epigynial plate smooth, with fine spicules posteriorly, shape of plate helmet-like, between coxae II–IV, and bearing a chitinised anchor-like process in its anterior half. A pair of lyrifissures is located near the anterior border of the sternal plate. Ventral region with 7 pairs of ventral opisthonotal setae and numerous lateral setae. All ventral opisthonotal setae serrated proximally, resembling dorsal plate setae. Peritremes located at level of coxae II–III, anterior prolongation hook-like, its tip directed outward. Stigmatal openings not bearing a posterior prolongation. Pedofossal and metapodal area without surface ornamentation, endopodal plates and sternal region ornamented with a few small circular markings. Pedofossal grooves distinct and well developed, and without ornamentation. Post-anal seta (pas) absent.

Gnathosoma ( Fig. 3 View FIGURE 3 ). Chelicerae dentate, without nodus, movable digit 60 µm long, fixed digit and its basal elongation (Cmp) total length 157.5 µm long ( Fig. 3 View FIGURE 3 A). Hypostomal setae h1 simple, smooth, needle-like, almost reaching end of laciniae; setae h2, h3, h4 serrated. Setae h2 with 4–6 denticles on both sides; h4 with 5–6 fine denticulations laterally, h3 longer than h2–h3, with 2–3 lateral denticles. Corniculus hornlike. Hypostomal constrictions present between h3–h4; surface of pro- and deutosternum finely denticulate ( Fig. 3 View FIGURE 3 B). Tritosternum vase-shaped basally, with three branches, and each branch bifurcate apically, its medial lacinia longer than others; tips of laciniae denticulate ( Fig. 3 View FIGURE 3 C). Ligula triangular, its surface with spiculate, basal margins with 3 denticles ( Fig. 3 View FIGURE 3 D). Epistome with triangular base and denticulate lateral margins, denticles gradually lengthening from tip to base ( Fig. 3 View FIGURE 3 F). Palps short and robust, palp tarsus with a set of tactile setae and thick prong-like setae, ventral setae of trochanter and some setae of femur and genu finely denticulate ( Fig. 3 View FIGURE 3 E).

Legs ( Fig. 4 View FIGURE 4 ). Coxae I large, tarsi I without claw, legs II–IV with a pair of claws at tip of the ambulacral prolongation; leg setae both simple and denticulate. Whip-like seta of tarsus I longer than tarsus. Femurs and trochanters I–IV bearing a membranous flange.

Male. Ven t er ( Fig. 5 View FIGURE 5 ). Genital plate oval, elongate, located between coxae III–IV, 67 µm long and 45 µm wide. Sternal region with scattered circular markings, 5 pairs of short and thorn-like (st1–st5) setae. Setae st1 arise from level of coxae II, st2 between coxae II–III, st3 close to anterior end of coxa III, st4 between coxae III–IV, outside genital plate, and st5 behind genital plate. A circular pore accompanies each setae near its base.

Other morphological features, setal arrangement, body shape and patterns as for female.

Deutonymph. Idiosoma 560–600 µm long, 460–500 µm wide.

Dorsum ( Fig. 6 View FIGURE 6 ). Dorsal plate with 33–35 pairs of relatively long setae, setae with fine spicules in proximal half, and whip-like in distal half as for adults. All setae long enough to pass insertion of following seta. Lateral setae dagger-like, curled upward at tip. Two pairs of posteriorly situated setae similar to spiculate dorsal setae.

Ven te r ( Fig. 7 View FIGURE 7 ). Sternal plate ornamented with fine punctation. Sternal plate anvilshaped, bearing five pairs of simple, smooth, needle-like setae st1–st5; 310 µm long and 130 µm wide. Anal plate setae similar in shape to dorsal shield setae. Anterior end of peritreme long and slightly twisted exteriorly. Stigmata located between coxae II–III, without a posterior prolongation. Pedofossae distinct, well developed; posterior margin of pedofossae IV pointed. Ventri-anal plate convex anteriorly, without ornemantation, 115 µm long and 245 µm wide. Anal plate with 2 pairs of smooth pointed setae. Distance between coxae II, III and IV: 97, 150, 195 µm, respectively.

Gnathosoma. Hypostomal setae h1 simple, needle-like, smooth; setae h2–h4 denticulate. Epistome, tritosternum, chelicera and other gnathosomal features as in adults, but slightly less robust.

Protonymph and larva. Unknown.

Remarks. Uropoda turcica sp. nov. is closely related to species of Cilliba , by having a well marked pedofossae, a dorso-ventrally flattened body, many marginal setae, five pairs of sternal setae, five pairs of simple ventral setae and two pairs of simple adanal setae, a V-shaped peritreme without posterior prolongation, 6-branched tritosternum with broad base, a chelicerae without nodus, and leg I tarsi without claws.

The new species differs from all congeners by virtue of its dorsal, ventri-anal and adanal setae which are spiculate proximally part and elongate and whip-like distally. The submarginal setae are longer and more robust than those of other closely related species. Additionally, in comparison to other congeneric species, the female of the new species has some distinctive characters, such as a large helmet-shaped epigynium with a chitinised anchor-like process in its anterior half, without surface ornamentation, located between coxae II–VI, and a porous sternum marked with well-developed endopodal lines.

Deutonymphs of the new species are differentiated from those of related species by having dorsal, ventri-anal and adanal setae basally serrated, but slimmer than those of adults.
