Potential problems with identification

Diabrotica nigrocincta Baly is very similar to D. h1n sp. nov. and D. hogei Jacoby. They can be separated by the following features: the legs are entirely black in D. nigrocincta, while femora are yellow in D. h1n and D. hogei; the armament of the internal sac is quite different in all three species.
