description: Parasyrisca polchaninovae sp. n.
Figs 2 a–d, 4a–c, 5h, 6e–h, 9a–c, 10a, 11
Types. Holotype ♂ (ZMMU) MONGOLIA, Khovd Aimag, Bumbat-Khairkhan-Bogd Mt. Range, Degnuult Mt. (47°12’N, 93°08’E), stony alpine meadow, 3000–3200 m, 24.06.2017 (A.A. Fomichev). Paratypes: 2♂ 1♀ (ZMMU), 3♂ (ISEA) together with the holotype.
Etymology. The specific name is a matronym in honour of Nina Yu. Polchaninova (Kharkov, Ukraine), the well-known Ukrainian araneologist.
Diagnosis. The male of P. polchaninovae sp. n. differs from the similar P. szinetari sp. n. by thinner conductor (cf. Figs 4b, 6e and 4e, 6a) and claw-like embolus (Figs 5h, 6g, h) vs. rectangular embolus composed of 2 parts (Figs 6 b–d). The female of P. polchaninovae sp. n. differs by having a thin arch-shaped posterior pocket of the epigyne (Figs 9 a–c) vs. wide anchor-like posterior pocket (Figs. 9 d–f) and possessing of receptacular heads of a kind lacking in sibling species.
Description. Male (holotype). Total length 9.0. Carapace 4.0 long, 3.25 wide. Colouration: carapace brown. Sternum, labium, endites and chelicerae dark brown. Palps: Fe–Pt pale yellow, Ti and cymbium yellow-brown. Legs yellow, darkened distally. Mt–Ta of leg I brown. Abdomen and spinnerets yellow-gray. Leg spination: I: Fe d2 p1, Ti v4, Mt v2; II: Fe d2 p2, Ti v3, Mt v2; III: Fe d2 p2 r1, Ti p3 r2 v5, Mt d1 p1 r1 v2; IV: Fe d2 p2 r1, Ti p2 r2 v5, Mt d2 p1 r 1 v 2. Leg measurements: I 14.95 (4.00, 2.10, 3.80, 3.05, 2.00); II 12.65 (3.45, 1.90, 3.00, 2.50, 1.80); III 11.05 (3.00, 1.65, 2.50, 2.25, 1.65); IV 15.10 (4.25, 1.80, 3.65, 3.40, 2.00).
Palp as in Figs 2 a–d, 4a–c, 5h, 6e–h. Tibia with apophysis bearing transverse ridge on posterior part. Cymbium elongate droplet shaped, 2 times longer than wide. Conductor over 5 times longer than wide, terminal 1/3 bent dorsally; embolus broad, with longitudinal ridges and claw like tip. Terminal and median apophyses without modifications.
Female. Total length 6.55. Carapace 3.0 long, 2.4 wide. Colouration: carapace light brown. Sternum, endites and chelicerae brown. Labium dark brown. Palps: Fe–Ti pale yellow, Ta brown. Legs: Fe–Pt yellow, Ti yellowbrown, Mt–Ta brown. Abdomen yellow-gray. Spinnerets pale yellow. Leg spination: I: Fe d2, p1, Ti v4, Mt v2; II: Fe d2, p2, Ti v3, Mt v2; III: Fe d2, p2, r2, Ti p3, r2, v4, Mt d1, p1, r1, v2; IV: Fe d2, p1, r1, Ti p3, r2, v5, Mt d2, p1, r1, v2. Leg measurements: I 8.70 (2.45, 1.40, 2.00, 1.60, 1.25); II 7.85 (2.10, 1.25, 1.80, 1.45, 1.25); III 7.45 (2.15, 1.15, 1.60, 1.45, 1.10); IV 10.30 (2.85, 1.35, 2.50, 2.25, 1.35).
Epigyne as in Figs 9 a–c. Anterior and posterior pockets arch-shaped; posterior pocket almost not subdivided into 2 parts; copulatory opening located in anterior 1/3 of fovea; receptacles and their ducts concave; receptacle as long as wide with long heads (Rh), heads 1.5 longer than wide, equal in width to receptacular ducts, heads separated by more than 2 diameters.
Size variation. Males vary from 8.0 to 9.7 in the body length, carapace 3.3–4.2 long, 2.5–3.2 wide (n=3).
