Figures 1 –15, 17– 20View FIGURE 1View FIGURES 2 – 8View FIGURES 9 – 14View FIGURES 15 – 24

Type material: Holotype ♂ ( ISEA, 000.856) Russia, Altai Republic, vicinity of Gorno-Altaisk, 400 m a.s.l., 51 ° 57 'N, 85 ° 54 'E, kitchen garden, hand collecting, 27.07. 2012 (L.A. Trilikauskas). Paratypes: 1 ♂ ( ISEA, 000.859), 1 ♂ ( ISEA, 000.857) same locality, hand collecting, 14.04. 2012, 27.07. 2012 (L.A. Trilikauskas); 1 ♀ ( ISEA, 000.858) same locality, hand collecting, 0 2.06. 2011 (L.A. Trilikauskas).

Comparative material: Alopecosa pulverulenta (Clerck, 1757)  : RUSSIA: 3 ♂ 1 ♀ ( ISEA) Altai Region, Zarinsk District, Salair Mt. Range, near Tyagun, 53 ° 53 'N, 85 ° 47 'E, 9.05. 1999, 4.09. 1999 (G.N. Azarkina). Alopecosa cuneata (Clerck, 1757)  : RUSSIA: 114 ♂ 1 ♀ ( ISEA) Novosibirsk Area, Zdvinsk District, nr Shirokaya Kur'ya Vill., 54 ° 36 'N, 78 ° 12 'E, abandoned field with natural cereals overgrowing, pitfall traps, 25.05. 2014 (A.N. Bespalov).

Etymology. The specific epithet derives from the Russian word "ogorod", meaning "kitchen garden", where the type series was collected.

Diagnosis. The new species belongs to the Alopecosa pulverulenta  -group (sensu Kronestedt 1990). Its colouration and body size ( Figs 17–20View FIGURES 15 – 24) are similar to those of A. cuneata (Clerck, 1757)  ( Kronestedt 1990: figs 13 H, I), but in the new species, the tibiae of leg I is not swollen ( Fig. 15View FIGURES 15 – 24, arrowed), whereas it is swollen in A. cuneata  ( Fig. 16View FIGURES 15 – 24, arrowed). The shape of tegular apophysis is similar to that of A. taeniata (C.L. Koch, 1835)  ( Kronestedt 1990: figs 4 C, D), but its distal part is wider and with an uneven edge in the new species ( Figs 6View FIGURES 2 – 8, 11View FIGURES 9 – 14). The terminal part is similar to that of A. pulverulenta  ( Kronestedt 1990: fig. 5 D), but the basal part of the embolus is narrower and the embolic tip has the appearance of being cut off obliquely ( Fig. 13View FIGURES 9 – 14). The embolic membrane of A. ogorodica  ( Figs 5View FIGURES 2 – 8, 12View FIGURES 9 – 14) differs from that of A. aculeata  , A. cuneata  , A. pulverulenta  and A. taeniata  ( Kronestedt 1990: figs 5 A-D). By its anterior, undivided pocket ( Figs 7, 8View FIGURES 2 – 8), the epigyne of the new species is similar to that of A. pulverulenta  ( Kronestedt, 1990: fig. 8 H), A. pinetorum (Thorell, 1856)  and A. pseudocuneata (Schenkel, 1953)  . It differs in the shape of the epigynal septum – almost identical with A. pulverulenta  , but differs in the form of the ductal parts of the receptacula: long and strongly curved in A. pulverulenta  ( Lugetti & Tongiorgi 1969: figs 5 f –m) and short and straight in A. ogorodica  ( Fig. 8View FIGURES 2 – 8). Alopecosa pinetorum  has a wide septum with a subtle chink between the septum and body ( Lugetti & Tongiorgi 1969: fig. 11 f) and the long ductal part of receptacula curves inwards ( Lugetti & Tongiorgi 1969: fig. 11 e); while A. ogorodica  has a more narrow septum with big space between it and the body ( Fig. 7View FIGURES 2 – 8), the ductal part of the receptacula is also different. The new species differs from A. pseudocuneata  by the wider septum and longer ductal parts of the receptacula ( Song et al. 1999: fig. 187 N).
