C. riparius sensu Sasa & Kamimura is not clearly separated from C. trinigrivittatus Tokunaga, 1940 (described from Sakhalin), in the hypopygial structure, although the colour patter and size of the body are different. The former has abdominal tergites 2–4 each with a broad brown band, on the other hand the latter has nearly uniformly darkened abdomen.
