Diagnosis.

The species differs distinctly from Xerolycosa mongolica by the carapace pattern, having a light longitudinal band and stripes. Males can be distinguished from those of Xerolycosa nemoralis by the shorter seminal duct, a bent free part of the embolus and a bent tip, a rounded (not pointed) process of the tegular apophysis, basal part higher than apical (equal in Xerolycosa nemoralis ), and the lack of a tegular ridge. Females can be distinguished by the proportions of the epigyne (windows longer than wide, whereas in Xerolycosa nemoralis they are wider than long).

Description.

Male.

Total length 5.0 (4.7-6.2). Carapace: 2.85 (2.52-3.09) long, 2.1 (1.79-2.22) wide. Carapace length/femur IV ratio 1.2. Habitus and pattern as in Fig. 6; carapace with wide white median band and marginal light stripes.

Palp as in Figs 22, 27-28, cymbial spines poorly distinct, upper part of tegular apophysis with claw-like outgrowth; embolus relatively thin, following an oval course, tip modified.

Female.

Total length 7.0 (4.8-7.4). Carapace: 3.0 (2.46-3.28) long, 2.1 (I. 71-2.42) wide. Carapace length/femur IV ratio 1.25. Habitus and pattern as in Fig. 7; pattern on carapace same as in male but with less distinct lateral light stripes.

Epigyne as in Figs 31-34, sides of stem rounded, windows shaped like inverted droplets, their upper margins almost horizontal.

Distribution.

Xerolycosa miniata has a Euro-Mongolian boreo-nemoral range ( Marusik et al. 2000) and is known from Portugal to Tuva, north to central Finland and north Ural, and south to Azerbaijan and north-western Mongolia.
