Diagnosis: Embolus thin, flat, bent at its tip. PTA small, triangular. RTA wide, triangular.

Legs sandy coloured, with poorly visible longitudinal dark stripes and dark splashes around spines. Measurements (n= 3). Body length 3.25–4.25.

Length of leg segments: FeI 2.35–3.35, PaI 0.83–0.9, TiI 2.25–3.2, MtI 2–2.9, TaI 1.25–1.65, FeII 3–4.2, PaII 0.9–1.25, TiII 3–4.25, MtII 2.65–3.75, TaII 1.5–2.05, FeIII 2–2.9, PaIII 0.65–0.9, TiIII 1.8–2.4, MtIII 1.55–2.15, TaIII 0.85–1.2, FeIV 2.35–3.3, PaIV 0.75–0.95, TiIV 2.05–3, MtIV 1.95–2.7, TaIV 0.85–1.3. Total length of legs: legI 8.68–12, legII 11.05–15.5, legIII 6.85–9.55, legIV 7.95–11.25. Spination of leg I: femur: d 0–0–1–0–1; pl 0–0–1–1–0 or 0–0–1–1–1; v -; rl 0–0–1–0–1. tibia: d 0–0–1; pl 1–1–0–1–0; v 2–0–2–0–2ap; rl 0–0–1–0–1. metatarsus: d -; pl 1–0–1–0–1; v 2–0–2–0–0ap; rl 1–0–1–0–0.

Palpus (Figs 33–35). CyL 0.67–0.73, CyW 0.31–0.34, PTiL. 0.31–0.34. Embolus medium wide basally, narrowing and curved toward its tip. The PTA sclerotised on its prolateral side, with a poorly visible triangular projection (claw) on its retrolateral view. The VTA flat and poorly sclerotised. The RTA narrow, bent and directed apically and sharply pointed in ventral view.

Female unknown.

Remarks: Compared to other species of the histrio group, P. timidus seems to possess a unique position and shape of the embolus (Figs 33, 34). The embolus is flat, narrowed and bent at its tip, with no PTA marked. The latter character relates this species to P. xinjiangensis, from which it can be separated the well-marked embolus and the slender RTA (cf. Figs 36, 37). The female of P. timidus remains unknown.

Habitat. No data. Elevations: 8–680 m a.s.l.

Distribution: A few records in Kazakhstan; for the collection localities see Map 10.

Etymology: The name of the species means shy, timid.
