Abstract

This study revises the subgenus Burlinius Lopatin, 1965 of the genus Cryptocephalus Geoffroy, 1762 (Coleoptera, Chrysomelidae, Cryptocephalinae, Cryptocephalini) and reports three new species, namely, Cryptocephalus (Burlinius) longchiensis sp. nov., C. (Burlinius) baowenzhengi sp. nov., and C. (Burlinius) tomurensis sp. nov.. The species C. (Burlinius) yangweii Chen, 1942 is revalidated and treated as a distinct species. Another four species are transferred to this subgenus from the subgenus Cryptocephalus s. str., namely, C. (Burlinius) flavolimbatus Pic, 1920 (stat. nov.), C. (Burlinius) pusus Schöller, 2009 (stat. nov.), C. (Burlinius) scutemaculatus Tan, 1992 (stat. nov.), and C. (Burlinius) shaowuanus Gressitt & Kimoto, 1961 (stat. nov.). Two species (including one more subspecies) are moved out of this subgenus, namely, C. (Burlinius) nigrolimbatus Jacoby, 1890, C. (Burlinius) pallidipes pallidipes Pic, 1927, and C. (Burlinius) pallidipes nakatae Gressitt & Kimoto, 1961; they are the members of the subgenus Cryptocephalus s. str.. Thus, the subgenus Burlinius Lopatin includes now a total of 25 species in China according to our revision. A key to all the Chinese species of this subgenus is provided as well as color illustrations and line drawing for general habitus and genital structures.
