Ceratomerus campbelli species-group

This unique species group is characterized by either a long comb of setae or three long spatulate processes on the anal lobe of the male wing, and the highly contorted and modified male midleg. Four species are included in this group, and together appear to be most closely related to the C. paradoxus group of southern Chile.
