We studied the type series of D. paradoxa in BMNH and in MCZ. The male paratype from Yzabal in BMNH and female paratype from Teleman in MCZ are different species.
Diabrotica paradoxa Jacoby is very similar to D. pulchra (Sahlberg), D. p2n, D. p3n and D. p4n. They can be separated by the following features: there are three black bandsbands:
(here) transverse maculae on the beetle elytra
on elytra in D. paradoxa, but four black bandsbands:
(here) transverse maculae on the beetle elytra
on elytra in all other species; scutellumscutellum:
small, usually triangular shield between the bases of elytra
is yellow in D. paradoxa, but black or amber brown in all other species.
