Diabrotica olivieri Jacoby is very similar to D. apicalis Baly and D. obscura Jacoby. They can be separated by the following features: elytra with apicalapical:
of or pertaining to the apex; opposite of basal
black macula on each elytronelytron:
<em>(pl. elytra)</em> the fore highly sclerotized wing of beetle
in D. olivieri, but completely yellow in D. obscura; D. apicalis is larger than D. olivieri; elytrla sides are almost parallel in D. apicalis, while the body shape in D. olivieri is roundish; elytra punctuation is stronger in D. olivieri than in D. apicalis, so elytra in D. olivieri have dull luster, whereas they are shining in D. apicalis.
