Smith and Lawrence (1967) placed D. fasciata in the genus Paranapiacaba Bechyné. The most important external morphological character that distinguishes Diabrotica from Paranapiacaba is a length of antennomere 3. This antennomere is at least 2 times as long as antennomere 2 in Paranapiacaba and subequal (not more than 1.5 times as long as the second) in Diabrotica ( Bechyné 1958, Smith and Lawrence 1967). Antennomere 3 in the lectotype and in all other studied specimens of D. fasciata is 1.5 times as long as antennomere 2. Antennomere 2 in Paranapiacaba is without setation, antennomere 3 has the same setation as antennomere 4, but it is denser on antennomere 4. In Diabrotica , antennomere 2 has sparse setation, as dense as setation on antennomeres 3 and 4. Antennomeres 2 and 3 in the D. fasciata type match the antennomere shape in Diabrotica . Smith and Lawrence stated that the lectotype of D. fasciata is a female. However, we studied the lectotype at MTD, and it is a male. The internal sac armament of D. fasciata ( Figs 77–79 ) is typical for Diabrotica species with 5 internal sac sclerites, mostly consisting of strongly sclerotized hooks or spines, similar to those of D. militaris Jacoby , D. circulata Harold , D. trifurcata Jacoby , etc. The armament of the internal sac in Paranapiacaba is different. Diabrotica fasciata was cited in the tricincta group of Paranapiacaba in Wilcox’s catalogue ( Wilcox, 1971). The armament of the internal sac in Paranapiacaba tricincta (Say) consists of weakly sclerotized structures that look like wide plates, toothed apically. Based on the internal sac armament and external morphological features, we restore the original combination Diabrotica fasciata .
