Diagnosis. The species habitus is similar to that of L. chabarovi and almost identical to L. folium . Larinioides cornutus can be distinguished from L. chabarovi by the copulatory organs. Unlike L. folium , it has a round outline of the epigynal median plate and reduced lateral lamellae ( Fig. 30 View FIGURES 26 – 32 ); its male palp lacks serration on the subterminal apophysis 2 ( Fig. 13, 14 View FIGURES 13 – 16 , blue). The male palp of L. cornutus is similar to that in L. jalimovi , but lacks a long process at the base of subterminal apophysis 1 and a small spur on the internal side of the flat shield of embolus.

Description. Carapace, chelicerae and sternum uniformly brown. Abdomen dorsally with a brown folium and a pale cross ( Figs 6 View FIGURES 5 – 7 A, C). Legs yellow, darkly annulated.

Male. Total length 4.7–8.5. Carapace 2.1–4.2 long, 1.8–3.5 wide. Length of the first patella + tibia 3.0–6.0. Tibia II unmodified ( Fig. 3 View FIGURES 1 – 4 F), resembling other tibiae. Palp as in Figs 9 View FIGURE 9 F, 10 F, 13, 14: bulbus with a tapered terminal apophysis; blunt subterminal apophysis 1; slightly serrated subterminal apophysis 2; embolus with flat shield covering a thin tip; median apophysis with a flat, rounded lower part and a narrow upper one with blunt tip; conductor rounded.

Female. Total length 6.5–14.5. Carapace 2.4 –5.0 long, 1.9–4.5 wide. Length of the first patella + tibia 2.6–5.8. Epigyne as Fig. 30 View FIGURES 26 – 32 , scapus short and straight; median plate rounded anteriorly; lateral lamellae laterally indistinct, anteriorly folded into triangular lobes covering copulatory openings; basal lamellae present.

Distribution. The species has a circum-Holarctic range and is found north to the tundra zone ( Marusik et al. 2000). Levi (1974) assumed it was distributed across the Holarctic accidentally by humans. In our opinion, the occurrence of this species in the in remote areas of Chukotka and neighbouring Alaska indicates its natural dispersal without human influence.

Comments. With 99 taxonomic entries ( Platnick 2014), it is one of the best known orb-weaving spiders. There are, however, some misidentifications (e.g. Loksa 1972, Bakhvalov 1974), which could lead to misinformation about its distribution and biology. A complete revision of all references is impossible, since most of them have an insufficient description and/or illustrations.
