Abstract
We describe the first Chinese Caloneurodea, Sinaspidoneura magnifica nov. gen., nov. sp., from the middle Permian Yinping Formation. This new genus and species belongs to the small family Aspidoneuridae, previously known from two genera and species, one from the latest Carboniferous of France and another from the late early Permian of North America. This discovery shows that this order was more widespread during the middle Permian than previously supposed, under a great variety of palaeoclimates. This clade is still unknown in the late Permian, and possibly became extinct because of the crisis of biodiversity that happened at the end of the middle Permian.
