Potential problems with identification

Diabrotica luciana Blake is very similar to D. fucata (Fabricius). They can be separated by the following features: there are three maculae on the elytra of D. luciana, but two macula in D. fucata; internal sac sclerite 4c in D. fucata is longer than in D. luciana.
