Potential problems with identification

Diabrotica spangleri Derunkov, Prado, Tishechkin, Konstantinov is very similar to D. pulchra (Sahlberg), D. salvadorensis, and D. perkinsi. They can be separated by the following features: there are five internal sac sclerites in D. spangleri, but four sclerites in D. salvadorensis; the hook at the base of sclerite 5A is thick and strong, folded on another side with associated flat plate in D. spangleri, but hook and plate in sclerite 5A lie in the same plane in D. pulchra; sclerite 5A is a pointed hook widened basally and bearing a short pointed hook on the base in D. perkinsi; legs are yellow with bicolored tibiae in D. spangleri, but femora are bicolored in D. perkinsi, and legs are black in D. salvadorensis; there are three bands on elytra in D. spangleri, but four bands in all other species.
