Abstract
BACKGROUND: Approximately 120 species of the chrysomelid genus Gonioctena are currently known from Palaearctic, Nearctic and Oriental Regions, amongst them, 51 occur in China. NEW INFORMATION: Two new species of the genus Gonioctena, G.klapperichi sp. nov. (Fujian) and G.oberthueri sp. nov. (Sichuan), are described and illustrated from China. Distinguishing characters from closely-related species are presented, respectively. The Gonioctena fauna of China now includes 53 species, of which about 60% are endemic. Ovoviviparity is newly recorded in G.oberthueri sp. nov.
