Species of the genus Syntozyga Lower, 1901 (Lepidoptera, Tortricidae, Olethreutinae) from China are studied. Syntozyga apicispinata sp. nov. and S. similispirographa sp. nov. are described, S. pedias (Meyrick, 1920) is recorded for the first time from China, and S. spirographa (Diakonoff, 1968) is newly recorded from the Chinese mainland. Adults and genitalia are illustrated, and a distribution map of the Chinese species is given. Keys to identify the Chinese species of Syntozyga are provided. Species of the genus are well clustered in a neighbor-joining tree based on the sequence data of the COI gene. COI sequences corresponding to the new species and S. spirographa (Diakonoff, 1968) are submitted to BOLD.
