Interestingly, there are remarkable differences in body lengths among this group. The species with the smallest adults, C. nanus , is only 1.51–160 mm long, whereas the largest one, C. hippopotamus View in CoL , has BL 2.32 mm. Three new species are described from China.

C. spatulatus sp. nov.

- In dorsal view, distal subapical dorsal projection small or not visible, if present then much shorter than apical lateral projections; in lateral view, distal region of paramere short and not projecting or only slightly projecting beyond basal capsule......... 2

2 BL about 2.3 mm; in ventral view, apical lateral projections of aedeagus separated by space much wider than width of each projection; in lateral view, proximal subapical dorsal projection conspicuously long and slender, transverse in relation to long axis of aedeagus and with strongly curved apex..................................... C. hippopotamus Jałoszyński View in CoL
