Potential problems with identification

Diabrotica amecameca Krysan & Smith is very similar to D. barberi Smith & Lawrence and D. virgifera zeae Krysan & Smith. They can be separated by the following features: the head and the legs are darker in D. amecameca. The internal sacs of aedeagus are different in all three species.
