This dataset contains the digitized treatments in Plazi based on the original journal article Xu, Zi Q., Yang, Nan, Oyama, Nozomu, Xu, Yanqi, Dong, Liyang, Ren, Dong, Béthoux, Olivier (2025): A new, large Permian Parelmoidae (Insecta, Megasecopteromorpha, Diaphanopterodea) found in Shanxi Province (China). Geodiversitas 47 (18): 705-712, DOI: 10.5252/geodiversitas2025v47a18, URL: sciencepress.mnhn.fr/sites/default/files/articles/pdf/geodiversitas2025v47a18.pdf ABSTRACT The insect family Parelmoidae Rohdendorf, 1962 belongs to the extinct order Diaphanopterodea Handlirsch, 1919, itself belonging to the larger taxon Megasecopteromorpha Béthoux in Yang, Ren & Béthoux, 2020.

Although generally rare, representatives of this family are a typical component of Permian environments, particularly in the Cisuralian, with occurrence in renowned localities such as Obora, Elmo & Midco, and Chekarda. Here we describe a new Parelmoidae, Grandelmoa jingqii n. gen., n. sp., known from a well-preserved, isolated wing discovered from a new locality, named ‘Zhiyu’ (Shanxi Formation; Shanxi Province, China).
