and are neither conspecific nor melanic variants of as assessed by micro CT analysis of their lectotypes (Insecta, Coleoptera, Chrysomelidae, Criocerinae).

The investigation of the type series of (Weise, 1880) and (Suffrian, 1841) using Micro-computed X-ray tomography (µCT) revealed that neither species is a melanic variant of (Linnaeus, 1758) as has been suggested previously. Lectotypes of (Weise, 1880) and (Suffrian, 1841) are designated based on the study of type material. The male genitalia of and differ to an extent in the shape of the median lobe and flagellum that their status as separate species is - cautiously - confirmed by the present study.
