Remarks

The internal sacs in male types of D. viridifasciata and D. duplicata have been examined. There are no differences in the internal sac armament in both species. The maculae on the D. duplicata elytra are definitely remnants of the reduced bands in D. viridifasciata . There are no substantial differences in the body shape and other morphological features in both species. The ranges of the both species overlap. Hereby we treat D. duplicata as synonym of D. viridifasciata.

 

Potential problems with identification

Diabrotica viridifasciata Jacoby is very similar to D. pulchra (Sahlberg), D. venancia Bechyné and D. relicta Suffrian. They can be separated by the following features: there are four bands on the elytron of D. pulchra, but only three in D. viridifasciata; the tibia in D. venancia and D. relicta are black, but yellow in D. viridifasciata.
