Abstract: The Gonioctena flavoplagiata species-group of the subgenus Asiphytodecta Chen, 1935 is defined and reviewed. Two new species are described and illustrated: G. (A.) jindrai sp. nov. (southwestern China) and G. (A.) truncaticornis sp. nov. (northeastern Laos). Gonioctena (A.) eburoides (Achard, 1924) stat. restit. is resurrected from synonymy with G. (A.) flavoplagiata (Jacoby, 1890). Lectotype is designated for G. (A.) flavoplagiata. A key to the species, diagnostic characters and illustrations are provided. Ovoviviparity is newly recorded in G. (A.) flavoplagiata and G. (A.) jindrai sp. nov.
Key words: Coleoptera, Chrysomelidae, Chrysomelinae, Gonioctena, Asiphytodecta, taxonomy, new species, lectotype, ovoviviparity, China, Laos, Vietnam
