Notes: * Gose’s (1969: figs 50 and 51) text and illustrations, which became the basis for the C. gosei description (Allen 1975), indicate that the outer margins of middle and hind femora have distinct serration; however, all specimens investigated by us (Fig. 15B, C) lacked distinct serrations on the femora. **According to Ishiwata (2003), specimens of C. orientalis from Japan have the maxillary palp reduced, but with distinct articulations of segments; specimens studied by us from Russia (Primorsky Krai) had the maxillary palp reduced, without distinct articulations.
