As the earliest record of the family Curvicubitidae Hong, 1984, Sinocurvicubitus qingjiangensis n. gen. n. sp. is established based on a cicada tegmen collected from the Laoshan Member of the Leping Formation in the Qingjiang Basin, Jiangxi Province, southern China. This new taxon is characterised by vein R forked at basal 1/3rd tegminal length, indentation at basal 2/3rds length, vein M first forked on nodal line, more developed M and less developed CuA. A Wuchiapingian age for this new species is suggested by the co-occurrence of the ammonoids Araxoceras tricarinatus and Pseudogastrioceras sp. The new find not only extends the known palaeogeographical range of curvicubitids in China, but also suggests an origin of this family in the Palaeozoic. This new record, combined with other records of Curvicubitidae, suggests a possibility of simultaneously northward and southward migration and dispersal of this family during the late Permian to the Late Triassic.
