Potential problems with identification

Diabrotica lopatini Derunkov, Prado, Tishechkin, Konstantinov is similar to D. palpalis Jacoby. They can be separated by the following features: penultimate joint of maxillary palpi is not incrassate in D. lopatini, but strongly incrassate in D. palpalis; elytra with three black spots on each elytron, one on basal part of elytra and two behind the middle in D. palpalis, but with only one small black spot behind the middle on each elytron in D. lopatini; humeral vittae occupy nearly the full length of elytron in D. lopatini, but only small humeral spots present in D. palpalis; scutellum is yellow in D. lopatini, but black or amber brown in D. palpalis.
