Potential problems with identification

Diabrotica linsleyi Krysan & Smith, is very similar to D. selecta Jacoby and D. tortuosa Jacoby. They can be separated by the following features: the antennae are bicolored in D. linsleyi, but unicolorous in D. selecta and D. tortuosa; elytra in D. linsleyi are with distinct discal sulci, which lack in D. selecta; there are three yellow maculae on each elytron in D. linsleyi, but four maculae in D. tortuosa.
