Melixanthus similibimaculicollis is also similar to M. menglaensis Duan, Wang & Zhou, sp. nov., but can be distinguished by the following characters: head without punctures; claws toothed (Fig. 2 C, D); and body size smaller.	en	Duan, Wen-Yuan, Wang, Feng-Yan, Zhou, Hong-Zhang (2021): Two new species of the genus Melixanthus Suffrian (Coleoptera, Chrysomelidae, Cryptocephalinae) from China.
