This study is based on a comprehensive morphological examination of physical specimens, high-resolution photographs, and primary literature covering all known species of the genus Meilichius Gerstaecker. Building upon this examination and utilizing specimens collected from China, three new species of Meilichius are described: M. chebalingensis Chang & Li, sp. nov., M. speciosus Chang & Bi, sp. nov. and M. tomaszewskae Chang & Bi, sp. nov.

Illustrations and diagnostic characters of the new species are presented, with a key to all known species of Meilichius. In addition, this study presents the first mitochondrial COI barcode data and ecological information for the recently described species M. wukong Wang & Tomaszewska.
