Potential problems with identification

Diabrotica martinjacobyi is very similar to D. curvilineata Jacoby. They can be separated by the following features: elytra in D. curvilineata are maculate with two small black spots on each elytron, in D. martinjacobyi elytra are maculate with two short black lines. The shape of the internal sac sclerite 6E is the most reliable feature that allows distinguishing two species.
