description: Alopecosa azsheganovae Esyunin, 1996 (Figs 1–19)

Novosibirsk Area: 178♂ 19♀, Zdvinsk District, nr Shirokaya Kur'ya Vill., 54°36–37'N, 78°10–15'E, 2009–2010 (A.N. Bespalov).

Diagnosis. Alopecosa azsheganovae is most similar to A. kasakhstanica Saveljeva, 1972 and A. psammophila Buchar, 2001. The male palps differ by the shape of the tegular apophysis – wide in A. azsheganovae (Figs 2, 9, 10) and relatively narrow in A. kasakhstanica and A. psammophila (Azarkina & Trilikauskas 2013: figs 21, 31 respectively). Females of A. azsheganovae differ from similar species by having a semicircular epigynal septum, with a thin septal ridge (Figs 4–5, 14) (anchor-shaped in A. kazakhstanica and A. psammophila).

Book lung plates and spinnerets yellow-brown to brown. Legs brown, covered with short, dark brown hairs, metatarsi and tarsi of all legs yellow-brown.

Habitus and pattern as in Figs 18, 19, nearly identical to the male. Heart mark distinct. Epigyne covered with white setae and brown bristles, as in Figs 19. Septum large, semicircular, covering 2/3 of fovea, stem thin: apical pocket width variable, with two separate chambers (Figs 4, 5, 14). Each receptacle with two subequally sized heads: ventral and dorsal (Figs 6–8, 15).
Habitat. Steppe and meadow steppe.
Comments. Based on the shape of the copulatory organs, A. azsheganovae can be placed in the fabrilis -group (see Lugetti & Tongiorgi 1969, p. 4).
Distribution. West Siberian nemoral range, from South Ural to NW part of Atlai Republic (Fig. 1).
