This paper defines and reviews the Gonioctena subgeminata species group of the subgenus Asiphytodecta Chen, 1935. The group contains the following five species, including two new to science: G. subgeminata (Chen, 1934), G. tonkinensis (Chen, 1934), G. oudai Cho & Borowiec, 2016, G. allardisp. nov., and G. mantilleriisp. nov. The species group restricted to China and Vietnam is characterized by a labrum without a tooth-like projection, elytral punctures arranged in discernible rows, and a setose aedeagus with a broad apical process. Gonioctena tonkinensis is newly reported as an ovoviviparous species. Habitus photographs, illustrations of diagnostic characters of each species, and a key to the species are provided.
