Potential problems with identification

Diabrotica lawrencei is very similar to D. hogei Jacoby and D. olivieri Jacoby. They can be separated by the following features: elytra are more convex in D. lawrencei than in D. hogei; D. lawrencei is larger in average than D. hogei; the armament of the internal sac is quite different in all three species.
