Potential problems with identification

Diabrotica redfordae is very similar to D. fenestralis Jacoby and D. morosa Jacoby. They can be separated by the following features: elytral epipleura in D. redfordae are completely black, narrow interior edge is pale or darkened from basal third to half, but completely yellow in D. fenestralis; femora of D. redfordae are bicolored, but the legs are entirely black in D. morosa. On average, Diabrotica redfordae is larger than both other species.
