Remarks

The lectotype for Galleruca quadrinotata is designated here to have a unique bearer of this name and the standard for its application. Zimsen (1964) only mentioned one syntype in Kiel, although two were included here. They represent two different species of Omophoita . Which species is correct was however apparent by the original description, mentioning ‘annulo obscuriori cinctis’, meaning, ‘surrounded by a darker ring’. The lectotype is missing segments 2–11 of its right antenna and segments 7–11 of its left antenna. Furthermore, it is missing both hind legs and several tarsal segments. The status of the metatarsal segment could not be determined, but the species is well known in collections and represents all characteristics of the genus Omophoita . We confirm the correct placement by the following characters: pronotal lateral explanation narrow, anterolateral corner of pronotum with lateral side straight, projecting directly forward, thickened, intercoxal prosternal process narrow (see also Konstantinov et al. 2022).
