1. Campsomeriella ilanensis (Tsuneki, 1972)

Only the male holotype of Campsomeriella ilanensis from Taiwan is known. According to the description and drawings by Tsuneki (1972), C. ilanensis is very similar to C. (C.) collaris quadrifasciata (Fabricius, 1798) (Fig. 3a–h) and it could be a synonym of the latter. We include images of the female of C. (C.) c. quadrifasciata (Fig. 4a–d) for comparison with this variable species.
