Potential problems with identification

Diabrotica venancia Bechyné is very similar to D. relicta Suffrian. They can be separated by the armament of the internal sac: there are five sclerites in internal sac in D. venancia, but four in D. relicta. The shape of the internal sac sclerites allows distinguishing Diabrotica venancia from D. relicta too.
