Potential problems with identification

Diabrotica brevilineata Jacoby is very similar to D. apicicornis Jacoby and D. septemliturata Erichson. They can be separated by the following features: the femora and maxillar palpi of D. apicicornis are black, but yellow in D. brevilineata; the labrum of D. brevilineata is yellow, but black in D. septemliturata. However, the most reliable feature that allows distinguishing D. brevilineata is the shape of the internal sac sclerites.
