Material examined: SLOVAKIA: 1 ♂ 1 ♀ (15 September 2010): Rapovce, 48 ° 16 ’N 19 ° 41 ’E, 176 m, Ľ. Černecká (LC); 1 ♂ (9 June 2006), 1 ♀ 1 sub.♂ (4 June 2008): Bratislava, on the wall, near Danube River, 48 ° 9 ’N 17 ° 4 ’E, 139 m, A. Šestáková ( AS); 1 ♀ (26 June 2008): Senica, Kunov, on the fence near pond, 48 ° 42 ’N 17 ° 25 ’E, 227 m, A. Šestáková ( AS); 1 ♂ (31 July 2009), 1 ♀ (18 September 2009): Vrútky, bus station, 49 ° 7 ’N 18 ° 56 ’E, 380 m, A. Šestáková ( AS).

Diagnosis. The species resembles L. ixobolus and L. jalimovi , but is distinguished by typical white hairs on carapace, median apophysis have a unique small apical spur ( Fig. 10 View FIGURE 10 C), embolus lack flat shield and terminal apophysis is rounded ( Figs 21, 22 View FIGURES 21 – 24 ). Epigyne can be distinguished by the sclerotised lateral lamellae protruding on its base ( Fig. 28 View FIGURES 26 – 32 ).

Description. Carapace brown with paler pattern with dense white hairs on the head region. Chelicerae spotted, sternum uniformly brown or with pale spot in the middle. Dorsum of abdomen with brown folium and white bordered pale cross or with indistinct pattern as in L. ixobolus ( Figs 3 View FIGURES 1 – 4 A, C). Legs yellow and dark annulated, femur ventrally dark spotted.

Male. Total length 6.0–8.0. Carapace 3.2 –4.0 long, 2.7–3.5 wide. Length of the first patella + tibia 5.3 –8.0. Tibia II not modified ( Fig. 8 View FIGURE 8 C). Palp as in Figs 9 View FIGURE 9 C, 10 C, 21, 22, 25 C; bulbus with rounded terminal, subterminal apophysis 1 and 2; embolus simple, without flat shield; median apophysis with small apical spur on the broader part of bifurcation; conductor rounded, higher then wide.

Female. Total length 8.0– 14. Carapace 3.9–5.3 long, 3.1–4.6 wide. Length of the first patella + tibia 4.4–10.2. Epigyne as in Fig 28 View FIGURES 26 – 32 ; round, bordered with lateral lamellae, apically covering copulatory ducts and basally protruding as flat round plates; scapus slightly curved.

Distribution. Platnick (2014) mentions that this species has a Holarctic distribution, but it is restricted to the Nearctic and Western Palaearctic, while records from the Far East ( Namkung 2002, 2003) refer to L. jalimovi . We agree with Levi (1974) that this species was very likely introduced to the Nearctic by humans.

Comments. Araneus sclopetarius is confused with L. cornutus in the figures by Clerck (1757). Therefore the name Araneus sclopetarius Clerck, 1757 becomes a junior synonym of L. cornutus and the senior synonym of A. sclopetarius , Araneus sericatus Clerck, 1757 , is revalidated. This conclusion is based not only on abdominal patterns but also on the terminal apophysis, which is clearly tapered and curved upwards, not rounded as in L. sericatus . This misidentification has confused other arachnologists, e.g. Blackwall (1864), Becker (1896).
