Diabrotica waltersi is very similar to D. elegantula Baly. They can be separated by the following features: the body of D. waltersi is more convex and shorter than in D. elegantula; the medium maculae are almost round in D. waltersi, while transverse in D. elegantula; the color of the bandsbands:
(here) transverse maculae on the beetle elytra
is usually black metallic blue in D. waltersi, but black metallic green in D. elegantula.
