• Mesosciophilidae
• Middle Jurassic
• Jiulongshan Formation

A new genus within the family Mesosciophilidae, Jurasciophila gen. nov., with two new species, J. curvula gen. et sp. nov. and J. lepida gen. et sp. nov., are described and illustrated. They are established based on fossil specimens with bodies and complete wings. All of them were collected from the late Middle Jurassic Jiulongshan Formation of Daohugou in southeastern Inner Mongolia, China. Comparing with two known genera, Mesosciophilina (Kovalev, 1985) and Mesosciophilopsis (Blagoderov, 1994), the new genus has transitional characters. The distribution pattern of Mesosciophilidae is briefly discussed.
