Ceratomerus inflexus species-group

This Australian species group is characterized by laterally inflated male terminalia, where the epandrial lamellae are normally highly convex, R 2+3 is slightly to strongly deflected and arched around the stigma, and antennal segment 8 (second flagellomere) is much longer than wide. The relationship of this group remains doubtful, although appearing to be the sister group to all remaining Australian species exclusive of the C. ordinatus group.
