Smith and Lawrence (1967) recognized the only specimen (female) of D. adelpha in the Allard collection in the MNHN as a part of Harold’s original series. They designated it as the lectotype. The male in the Allard collection ( MNHN), bearing labels (1) [ Diabrotica adelpha Harold ] handwritten and (2) [Ex Musaeo Quedenfeldt] white, printed, is morphologically identical with the lectotype, except for gender-specific characters. We treat it as the male of D. adelpha and examined its genitalia ( Figs 3–5 View FIGURES 1 – 5 ). Male genitalia have been examined in six paralectotype males of D. flaviventris and 4 paralectotype males of D. tibialis ( BMNH and MCZ). Male genitalia of additional specimens of all three taxa in the USNM collection have been examined as well. The armament of the internal sac of the aedeagus is identical in all three taxa. In addition, they are very similar in the coloration patterns. Jacoby (1887: 511) wrote: “This [ D. adelpha ] and several of the following species [ D. tibialis , D. brunneosignata , etc.] are extremely closely allied, their characters of distinction being slight and variable”. The only two substantial differences in coloration between the lectotype females of D. adelpha and D. tibialis are as follow: in D. adelpha , the pronotum and tibiae are yellow or yellow ocher ( Fig. 2 View FIGURES 1 – 5 ); in D. tibialis , the pronotum is testaceous, while the tibiae are black or chestnut ( Fig. 11 View FIGURES 11 – 15 ). After studying large series of these two taxa, we recognized a few transitional coloration patterns of the tibiae from uniformly yellow through bicolored (yellow, outer edge with piceous or testaceous line, sometimes extensively darkened) to uniformly black or chestnut. The outlines of the elytral bands of all three taxa are very similar as well. Diabrotica flaviventris with almost entirely testaceous elytra, is probably a melanistic color morph of D. adelpha . No substantial differences exist in the body size or shape of all three species. Therefore, we treat D. tibialis and D. flaviventris as synonyms of D. adelpha .
