Potential problems with identification

Diabrotica curvilineata Jacoby is very similar to D. c1n, D. novemmaculata Jac. and D. palpalis Jac. They can be separated by the following features: elytra in D. curvilineata are maculate with two small black spots on each elytron, but maculate with two short black lines in D. c1n; the head in D. palpalis and D. novemmaculata is black, but yellow in D. curvilineata; the tarsi and tibiae of D. palpalis and D. novemmaculata are yellow, but black or extensively darkened in D. curvilineata; D. novemmaculata is larger than D. curvilineata.
