Potential problems with identification

Diabrotica reysmithi is very similar to D. militaris Jacoby, D. josephbalyi and D. fasciata Kirsch. They can be separated by the following features: band color is metallic black blue in D. reysmithi, but metallic black green in D. militaris and D. fasciata; round yellow spot on the basal band is larger in D. militaris than in D. reysmithi; the size and the shape of the band edges is different in all four species. Number of internal sac sclerites is four in D. reysmithi, but five in all other species. The shape of the internal sac sclerites allows distinguishing Diabrotica reysmithi from all other species too.
