Sinoagetopanorpidae fam. nov., a New Family of Scorpionflies (Insecta, Mecoptera) from the Guadalupian of South China

SIMPLE SUMMARY: Mecopterans have been sparsely reported from the Permian of China, despite their great biodiversity in the fossil record in the world. Herein, we describe and illustrate three genera (two new genera) and eleven species (ten new species) belonging to a new family Sinoagetopanorpidae f...

Sumario:SIMPLE SUMMARY: Mecopterans have been sparsely reported from the Permian of China, despite their great biodiversity in the fossil record in the world. Herein, we describe and illustrate three genera (two new genera) and eleven species (ten new species) belonging to a new family Sinoagetopanorpidae fam. nov. from the upper Guadalupian Yinping Formation of Anhui Province, China: Sinoagetopanorpa permiana Lin, Nel and Huang, 2010, S. nigra sp. nov., S. rotunda sp. nov., S. lini sp. nov., S. minuta sp. nov., S. elegans sp. nov., S. grimaldii sp. nov., S. magna sp. nov., Raragetopanorpa zhangi gen. et sp. nov., Permoagetopanorpa yinpingensis gen. et sp. nov. and P. incompleta sp. nov. Our new discovery indicates a high diversity of mecopterans in the Permian of China, and Signoagetopanorpidae might have evolved independently on the Yangtze Platform. ABSTRACT: Mecoptera was in great abundance in the Permian, but little is known from China. A new family, Sinoagetopanorpidae fam. nov., is described and illustrated from the upper Guadalupian Yinping Formation at Yinping Mountain, Chaohu City, Anhui Province, China. Sinoagetopaorpa permiana Lin, Nel and Huang, 2010 was previously attributed to Permochoristidae and now is revised as the type species of Sinoagetopanorpidae fam. nov. Three genera (two new genera) and ten new species of this new family are described and illustrated: Sinoagetopanorpa permiana Lin, Nel and Huang, 2010, S. nigra sp. nov., S. rotunda sp. nov., S. lini sp. nov., S. minuta sp. nov., S. elegans sp. nov., S. grimaldii sp. nov., S. magna sp. nov., Raragetopanorpa zhangi gen. et sp. nov., Permoagetopanorpa yinpingensis gen. et sp. nov. and P. incompleta sp. nov. Some isolated hind wings are described and illustrated, although it is difficult to assign them to any particular species. As a dominant mecopteran lineage in the Yinping Formation, Sinoagetopanorpidae represents an endemic group that might have independently evolved on the Yangtze Platform.
