Holotype: female, slide 2305, Russia, Chukotka, Anadyr District, Majorskoe Lake near settlement Markovo, depth 0.5–0.8 m, 29 June 1978, leg. P.V. Tuzovskij. Paratype: one female from the same locality and collection date as holotype. Description. Female. Idiosoma oval, integument soft and striated. Dorsum with small elongated platelets (Fig. 44). The number and position of idiosomal setae typical for the genus Piona. All dorsal setae thin and approximately equal in length, but setae Fch (Fig. 45) thicker than other idiosomal setae associated with glandularia (Fig. 46) and trichobothria (Fig. 47). Coxae of legs cover about half ventral surface (Fig. 48). Anterior coxal groups with short apodemes. Sclerites bearing setae setae Hv lying free and located between anterior and posterior coxal groups. Medial margin of coxal plates IV nearly twice longer than medial margin of coxal plates III. Posterior margins of coxal plates IV forming obtuse angle, apodemes slightly developed. Genital opening longer than acetabular plates, three pairs of genital setae located in integument between acetabular plates and pregenital sclerite and five pairs of thin setae placed in acetabular plates, four of which are located in posteromedial corner. Acetabular plates well indented on medial margin, with numerous genital acetabula (40–55), two pairs of which much larger than others; anterior large acetabulum located in anteromedial corner of acetabular plate, second large acetabulum situated approximately in center of the plate. Excretory pore surrounded by narrow sclerotized ring. Pedipalp rather slender (Fig. 49): P–1 with a single short dorsodistal seta; P–2 large, with straight ventral margin, bearing seven or eight dorsal setae; P–3 with one long and two relatively short unequal setae, base long seta located near middle of segment; P–4 longer than P–2, ventral setae located on tubercles, proximal tubercle a little smaller than distal one, distoventral spine short; P–5 ...
