200687A1FFFC6D39FF08FD4BFCE9FA5A.taxon	diagnosis	DIAGNOSIS. Female. Habitus can vary greatly among individuals (Yaginuma, 1959; Tanikawa, 1992 a; Zhu &, Zhang, 2011; Kim & Lee, 2012). Our specimen has a brown carapace darker to margins, eye region and posterior edge of head region. Sternum with two symmetrical round white spots. Legs light brown with wide dark brown rings. Abdomen elongated with blunt tip. Distal lateral tubercles are almost absent. Dorsal coloration silver with black outline, 3 pairs of muscle points, one median dark spot at the anterior edge and 3 symmetrical lateral dark spots. Epigyne as in Fig. 8. Scape is wide, long and parallel-sided, wrinkled, with obtuse end. Outer edges of lateral lamellae are evenly rounded, inner edges are closed from base to the middle point, and then diverge in an acute angle. Median plate medium-sized, triangle-shaped with almost straight top edge.	en	Tiunov, A. V., Ustinova, A. L.

200687A1FFFC6D39FF08FD4BFCE9FA5A.taxon	discussion	REMARKS. In the Russian Far East C. ginnaga may be confused with C. atrata and C. hamulata due to similar shape and coloration of abdomen. In C. ginnaga lateral lamellae of epigyne are closed until the middle and then diverge in an acute angle, edge not curved. Median plate is triangle-shaped, epigyne base is wider than high less than twice. Epigynes of C. atrata and C. hamulata differ by the concave median edges of lateral lamellae, pearshaped median plate and by the shape of the epigyne base: it is twice wider than high.	en	Tiunov, A.

200687A1FFFC6D39FF08FD4BFCE9FA5A.taxon	biology_ecology	ECOLOGY. The species is found in mountainous areas in meadows and bushes (Zhu & Zhang, 2011; Kim & Lee, 2012). Stabilimentum of the web is located at the hub and shaped as an uneven white marking, resembling bird droppings in appearance and size. If extrinsic objects do not get into the web, the spider is well protected from bird attacks (Tan et al., 2010).	en	Tiunov, A. V., Ustinova, A. L.

200687A1FFFC6D3BFF08FA0FFD95FAF8.taxon	diagnosis	DIAGNOSIS. Habitus of our specimen (Fig. 2) well agrees with original description of this species (Tanikawa, 1992 b). Palp as in Figs. 5, 10. Median apophysis of male palp (Fig. 7) basally has wing-shaped lamella. Distally median apophysis bent and bifurcated, while teeth are closely spaced or the bifurcation is not clear (Tanikawa, 1992 b). Terminal apophysis has wide base and narrow distal part, which form a furrow. Embolus basally wide and slightly narrows along entire length. Embolus has two bends – in the middle and closer to the end. Distal part of conductor is rather wide and round, with narrow notch at the tip.	en	Tiunov, A. V., Ustinova, A. L.

200687A1FFFC6D3BFF08FA0FFD95FAF8.taxon	discussion	REMARKS. Males of C. onoi differ from C. oculata by roundish shape of palpal conductor as well as the shape of median apophysis, smooth and rounded in C. oculata (Figs 6, 11) and more abrupt and angular in C. onoi (Figs 5, 7, 10). Palpal median apophysis of C. onoi basally has only a wing-shaped lamella, whereas C. oculata has a digitiform appendix along with a wing-shaped lamella (Tanikawa, 1992 b). During comparison of specimens of these species, we found that this trait cannot be considered as absolutely reliable, because appearance of these structures depends on an observation angle.	en	Tiunov, A.

200687A1FFFE6D3CFF08FAE8FD1CFDF2.taxon	discussion	REMARKS. In Russia this species may be confused with C. monticola and C. oculata by the shape of the abdomen, but females are easily distinguished by a very short and wide scape of epigynum.	en	Tiunov, A.
