Potential problems with identification

Diabrotica panamensis Jacoby is similar to D. morosa Jacoby. They can be separated by the following features: legs are bicolored in D. panamensis, but completely black in D. morosa; body shape in D. panamensis is roundish and convex, while flattened and slender in D. morosa.
