Remarks

The lectotype of this species had already been designated by Konstantinov et al. (2022). Presently, we confirm that the second specimen in Kiel is conspecific with the lectotype and treat it as a paralectotype. Its sex cannot be established as the wings cover the apical ventrite and the front tarsi are poorly visible. We confirm the correct placement in the genus Omophoita Chevrolat, 1836 based on 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).
