Legs in alcohol milk white with narrow dark ring. Abdomen oval with 4 distal humps. 4 dorsal muscle points form a trapezoid. Abdomen coloration light brown with white and brown patches, which fade and lose their shape in alcohol.

Epigyne as in Fig. 9 View Figs 8–11 , oval-shaped, scape short and wide with two rows of small seta at the middle. Lateral lamellae closing together above median plate, which is surrounded by lateral lamellae and has a butterfly shape.

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.

ECOLOGY. Webs with vertical stabilimenta are built on trees in dimly lit places ( Baba & Tanikawa, 2015).
