Remarks

The lectotype for Chrysomela quadrifasciata is designated here to have a unique bearer of this name and the standard for its application. The lectotype is missing all right legs, and the right antenna is missing segments 6–11. We confirm the correct placement in the genus Asphaera based on the following characters: distance between antennal sockets less than or equal to transverse diameter of antennal socket in frontal view, second antennomere about half as long as third antennomere, anterolateral callosity of pronotum long and directed anteriorly. Lateral margin of elytron widely explanate (see also Konstantinov et al. 2022).
