摘要

Two new genera and species of snakeflies (Raphidioptera) are described and figured from the Jurassic Jiulongshan Formation of eastern Inner Mongolia, China. Ororaphidia megalocephala, new genus and species, and Styporaphidia magia, new genus and species, are both differentiated from other Mesozoic snakefly lineages. These constitute the oldest records of snakeflies from China.
