A new species, Diapromorpha flavolabiata sp. nov. and new record of Diapromorpha sexmaculata (Jacoby, 1889) from China (Coleoptera, Chrysomelidae, Cryptocephalinae, Clytrini)

This paper describes one new leaf beetle species, Diapromorpha flavolabiata Zhou, Duan & Wang, sp. nov. from Yunnan, China. Diapromorpha sexmaculata (Jacoby, 1889) is recorded for the first time from Sichuan and Yunnan provinces of China. A key of all Chinese species of the genus Diapromorpha is included. For the new species and new record species we also provided color illustrations, line drawings of general habitus and other detailed structures to benefit identification and taxonomic studies in the future. All the types of the new species are deposited in the collection of Institute of Zoology, Chinese Academy of Sciences (IZ-CAS).
