Zodarion nenilini Eskov , in Eskov & Marusik 1995: 62, figs 27–29 (♂ ♀).

Zodariellum nenilini: Marusik & Koponen 2001: 42 , figs 1, 6, 10–13, 19–24 (♂ ♀).— Esyunin et al. 2007: 57, figs 21–23 (♂).— Marusik & Kovblyuk 2011: 277, figs 44.2. 4–5 (♂ ♀).

Material examined. KAZAKHSTAN: East Kazakhstan Region: 2♂ ( ISEA), W outreaches of Narym Mt. Range, Kaindy River Valley , 10–15 km SE of Slavyanka, [43°N 78°E], steppes, 6– 7.05.1999 (R. Dudko, I. Lyubechanski) ; 1♀ ( ISEA), northern Cis-Zaisan (=N cosat of Zaisan Lake), N part of Kuludzhun sands, [48°40'N 83°20'E], 8– 10.05.1999 (R. Dudko, I. Lyubechanski) .

Description. See Eskov & Marusik (1995) and Marusik & Koponen (2001). Habitus of male and female as in Fig. 1D, E . Male palp as in Figs 2C , 3C , 4C , 5C , 6C , 7D–F , 8D–F . Epigyne as in Fig. 10A : fovea (Fo) wider than long; copulatory ducts (Cd) contiguous and forming angle>90º.

Distribution. Known from South Urals (51°54'N, 55°20'E; Esyunin et al. 2007), east Kazakhstan (type locality) and Gobi-Altai and Bayankhongor Aimags (ca 101ºE) of Mongolia ( Marusik & Koponen 2001) ( Fig. 12A–B ). It is possible that the records from South Ural belong to Z. volgouralense Ponomarev, 2007 .
