Synchroidae Lacordaire, 1859 is a taxonomically and biologically poorly known group. In the present paper, diagnostic characters used to separate genera are analysed and the phylogenetic relationships within this family are preliminarily investigated. Results suggest that the characteristic Synchroa pangu Hsiao, Li, Liu & Pang, 2016 can be removed to establish a new genus, Thescelosynchroa gen. nov. The new combination, T. pangu (Hsiao, Li, Liu & Pang) gen. et comb. nov., is proposed. The definitions of Synchroa Newman, 1838 and Synchroina Fairmaire, 1898 are revised. Moreover, morphological analysis and character comparison also suggest that the familial placement of Mallodrya subaenea Horn, 1888 is questionable. Six species are re-examined and re-diagnosed: Synchroa chinensis Nikitsky, 1999, S. elongatula Nikitsky, 1999, S. formosana Hsiao, 2015, S. melanotoides Lewis, 1895, S. punctata Newman, 1838 and Synchroina tenuipennis Fairmaire, 1898. The male of S. chinensis and the female of S. formosana are described for the first time. Synchroa elongatula and Synchroina tenuipennis are newly recorded from Laos and Indonesia, respectively. We also hypothesize that the Eastern Asian-North American disjunction of Synchroa could be connected to a Mid-Late Tertiary migration of plants via the Bering Land Bridge.
