Parasyrisca bucklei Marusik & Fomichev, 2010, sp. n.

Parasyrisca bucklei sp. n.

Figs 1–6, 9–15

Etymology. The specific name is a patronym in honour of our colleague Donald J. Buckle (Saskatoon, Canada).

Material. RUSSIA: Holotype 3 and paratypes 5Ƥ (SZMN) Altai, Kuraisky Mt. Range, 50º20’N, 87º44’E, mountain stony tundra, 2800–3000 m, 5.07.2009 (A.Fomichev). 13 3Ƥ 1 juv. (ZMMU), same locality, 11– 12.07.2007 (P.Y.Ustyuzhanin).

Diagnosis. The new species is closely related to two Siberian species, P. logunovi Ovtsharenko, et al., 1995 and P. belengish Ovtsharenko et al., 1995 (see Ovtsharenko et al., 1995: figs 62–66, 75–76). It can easily be distinguished from the former species by the shape of its conductor with an extended terminal part (conductor with parallel lateral borders in P. logunovi) and the spermatheca terminating over the anterior hood. It can be separated from P. belengish by a more elongate terminal part of the spermathecae.

Description. Male. Total length 9.2–10. Carapace: 3.8–4.6 long, 3.2–3.6 wide. Cymbium 1.7–1.8 long. Body light brown without pattern. Palp as in Figs. 1–6. Tibial apophysis with five teeth (Fig. 6), embolus flat, partly exposed (Figs 1, 4), conductor with extended terminal part.

Leg article length of male with carapace 3.8 long and in female with carapace 5.3 long.

Femur Patella Tibia Metatarsus Tarsus Female. Total length 9.5–14. Carapace: 3.8–5.3 long, 3.2–4.1 wide. Colouration as in male. Epigyne (specimens with carapace 5.3 long) – 1.0 high and 0.9 wide. Epigyne as in Figs 9–15. Shape is variable, anterior hood small, posterior hood about three times wider, posterior part distinctly subdivided, lateral sides of fovea in most specimens almost parallel. Spermathecae with parallel sides, head of spermathecae elongate.

Comments. This species, like most species known from numerous females, demonstrates a rather strong variation in the shape of epigyne (Figs. 9–15).

Distribution. Only the type locality.
