摘要：

The family Campterophlebiidae Handlirsch, 1920 is the dominant Jurassic clade of Odonata Fab-ricius, 1793, especially hosting a high diversification in northern China. The Chinese campter-ophlebiid damsel-dragonflies were mainly recovered from the Middle Jurassic of Inner Mongolia, northern China. In the present study, a new campterophlebiid, Parasinitsia qingyunensis n. gen., n. sp., is described from the early Middle Jurassic Yanan Formation of the Ordos Basin, NW China. Parasinitsia n. gen. resembles the genus Sinitsia Pritykina, 2006 recorded from the Upper Jurassic of eastern Transbaikalia, but differs from the latter in having two or three rows of cells between RA and RP1 distal of the pterostigma, IR2 and RP3/4 with at least four rows of cells near the wing margin, and CuAa with about 15 rows of cells between it and the posterior wing margin in the broadest area. The new damsel-dragonfly comes from a new early Middle Jurassic insect site from the Ordos Basin, providing new clues to understand the terrestrial ecosystems during this epoch.
