description: This dataset contains the digitized treatments in Plazi based on the original journal article Tian, Fusheng, Zheng, Daran, Nel, André, Mei, Ting, Zhang, Haichun (2023): A new campterophlebiid damsel-dragonfly (Odonata: Isophlebioidea) from the Middle Jurassic Yanan Formation of Yulin City, Shaanxi Province, NW China. Comptes Rendus Palevol 22 (23): 491-496, DOI: 10.5852/cr-palevol2023v22a23, URL: http://dx.doi.org/10.5852/cr-palevol2023v22a23ABSTRACTThe family Campterophlebiidae Handlirsch, 1920 is the dominant Jurassic clade of Odonata Fabricius, 1793, especially hosting a high diversification in northern China. The Chinese campterophlebiid 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.KEY WORDS Campterophlebiidae, Yanan Formation, Middle Jurassic, Ordos Basin, China, new genus, new species. RÉSUMÉUn nouveau campterophlebiid demoiselle-libellule (Odonata: Isophlebioidea) de la formation Yanan du Jurassique moyen de la ville de Yulin, province de Shaanxi, au Nord-Ouest de la Chine.La famille Campterophlebiidae Handlirsch, 1920 est le clade jurassique dominant des Odonata Fabricius, 1793, avec notamment une forte diversité dans le Nord de la Chine. Les Campterophlebiidae de Chine proviennent principalement du Jurassique moyen de la Mongolie intérieure. Dans la présente étude, un nouveau Campterophlebiidae, Parasinitsia qingyunensis n. gen., n. sp., est décrit de la formation de Yanan du Jurassique moyen inférieur du bassin de l’Ordos, dans le nord-ouest de la Chine. Parasinitsia n. gen. ressemble au genre Sinitsia Pritykina, 2006 du Jurassique supérieur de l’est de la Transbaïkalie, mais diffère de ce dernier en ayant deux ou trois rangées de cellules entre RA et RP1 en aval du pterostigma, IR2 et RP3/4 avec au moins quatre rangées de cellules près du bord de l’aile, et CuAa avec environ 15 rangées de cellules entre elle et la marge postérieure de l’aile dans la zone la plus large. Le nouveau taxon provient d’un nouveau site d’insectes du début du Jurassique moyen du bassin de l’Ordos, fournissant de nouveaux indices pour comprendre les écosystèmes terrestres à cette époque.MOTS CLÉSCampterophlebiidae,Formation Yanan,Jurassique moyen,bassin de l’Ordos,Chine,genre nouveau,espèce nouvelle. INTRODUCTION The family Campterophlebiidae Handlirsch, 1920 is the most diversified damsel-dragonfly clade discovered from the Mesozoic of China, the majority of taxa being recorded from the Middle Jurassic of Inner Mongolia, and few in the Lower Jurassic of Xinjiang and the Middle Jurassic of Shaanxi (Fleck & Nel 2002; Nel et al. 2008, 2009; Zheng et al. 2016, 2017, 2018, 2019; Huang et al. 2018). Herein, we describe a new campterophlebiid damsel-dragonfly from the early Middle Jurassic Yanan Formation in Qingyun Village of eastern Yulin City, Shaanxi Province, northwestern China. The Yanan Formation in Huangjiagou Village of Yulin has already yielded a campterophlebiid damsel-dragonfly (Zheng et al. 2017). The present study describes a new genus and species of Campterophlebiidae, and reveals a new Middle Jurassic entomofauna from northern Ordos Basin.The family Campterophlebiidae Handlirsch, 1920 is the most diversified damsel-dragonfly clade discovered from the Mesozoic of China, the majority of taxa being recorded from the Middle Jurassic of Inner Mongolia, and few in the Lower Jurassic of Xinjiang and the Middle Jurassic of Shaanxi (Fleck & Nel 2002; Nel et al. 2008, 2009; Zheng et al. 2016, 2017, 2018, 2019; Huang et al. 2018).
