Five new Chinese species are described below. Within this group, the Japanese species C. mizunoi View in CoL , C. tamaki View in CoL and C. yonaguniensis View in CoL have been described in such a way that it is not possible to identify them, and it is also not possible to make sure that these are separate species. The illustrations given by Hoshina (2012, 2021), and Hoshina & Kishimoto (2004) are of exceptionally poor quality and cannot be used to identify species. Of the five newly described Chinese species, two have aedeagi slightly similar to those of the above-mentioned Japanese species, but not close enough to pose a risk of synonymy.

The C. simonis group may be a garbage dump for species that do not show any peculiar external characters, are small-bodied, and their aedeagi are similar in a general form. These species were previously treated as not placed in any group, but the newly proposed (not yet final) division facilitates identifications and reduces the number of unassigned species. A phylogenetic analysis is required to test the monophyly of this assemblage.
