Bowditch (1911) indicated the differences between D. bioculata and D. peckii as slightly different coloration of the antennae and elytra, details of pronotal foveation and elytral punctation. All these features are subject to intraspecific variation. We studied the internal sac of the aedeagus of the lectotypes of both species ( Figs 18–20 , 23–25 ) and found no substantial differences in the internal sac armament. Both lectotypes are very similar in their external features. Therefore, we treat D. peckii as a synonym of D. bioculata . In the type series of D. bioculata , one paralectotype from Jalapa, Mexico, at the MCZ is a different unidentified species.
