New Records of Grammolingiidae, Saucrosmylidae, and Panfiloviidae (Insecta: Neuroptera) from the Jurassic of Mongolia and Kyrgyzstan

摘要

New records of Saucrosmylidae from two Mongolian localities of Bakhar (upper Middle Jurassic-lower Upper Jurassic) and Khoutiin-Khotgor (Upper Jurassic) are reported. This is the first record of the family from Central Asia and the second finding outside the type locality of Daohugou (China). Two new species and a new genus, Chorilingia bakharica sp. nov. (Grammolingiidae) and Opapanfilovia bonata gen. et sp. nov. (Panfiloviidae) from Bakhar and Sai-Sagul (Kyrgyzstan, upper Lower Jurassic-lower Middle Jurassic) localities, respectively, are described. The complete list of known records of Grammolingiidae, Saucrosmylidae, and Panfiloviidae is provided. The clade Grammomorpha nom. nov. is introduced for the three families based on their venation characters. The analysis of the fossil record has shown that Grammomorpha was an exclusively Jurassic group that became extinct close to the Jurassic-Cretaceous boundary due to unknown causes.
