Potential problems with identification

Diabrotica fulvicornis Jacoby is very similar to D. apicicornis Jacoby, D. brevilineata Jacoby, D. palpalis Jacoby, D. septemliturata Jacoby and D. sedata Baly. They can be separated by the following features: head of D. fulvicornis is black, but yellow in D. apicicornis, D. brevilineata, D. septemliturata and D. sedata; maxillar palpi of D. fulvicornis are black, but yellow in D. brevilineata, D. septemliturata and D. sedata; labrumlabrum:
the "upper lip" of beetles, a movable sclerite joined under clypeus
of D. fulvicornis is black, but yellow in D. brevilineata; femora of D. fulvicornis are yellow, but black in D. apicicornis; D. sedata is larger on average than D. fulvicornis.
