Potential problems with identification

Diabrotica championi Jacoby is similar to D. g1n, D. regularis Jacoby and D. viridifasciata Jacoby. D. regularis is on average smaller than D. championi. The shape of the internal sac sclerites allows distinguishing Diabrotica championi from both other species.
