Diagnosis

Body length 5.4-6.3 mm, width 2.8-3.3 mm. Head basic color black. Antennae filiform, bi- or tricolored, antennomeres 1-3 yellow, antennomeres 4-8 gradually infuscated, antennomeres 9-10 yellow ocher, antennomere 11 completely yellow ocher or dark apically. Maxillary palpi yellow, labrum black or chestnut.

Potential problems with identification

Diabrotica duckworthorum Derunkov, Prado, Tishechkin, Konstantinov is very similar to D. trifurcata Jacoby. They can be separated by the following features: legs and scutellum are yellow in D. duckworthorum, while scutellum and tibia are brown or black in D. trifurcata; antennae are shorter and pronotum is narrower in D. duckworthorum than in D. trifurcata. Diabrotica duckworthorum is also very similar to the most of the "oculate" species, e.g. D. gratiosa Baly, D. adelpha Harold, D. biannularis Harold, D. bioculata Bowditch and D. pulchella (Jacquelin-du-Val). They can be separated by the following features: the tibiae of D. gratiosa and D. bioculata are black or dark brown, while yellow in D. duckworthorum; the pronotum of D. adelpha lacks foveae (bifoveate on D. duckworthorum), it also possesses more convex elytra and is larger than D. duckworthorum; D. pulchella is larger too; the scutellum of D. biannularis is black, while yellow in D. duckworthorum.
