New species of Grammolingia Ren, 2002 from the Middle Jurassic of Inner Mongolia, China (Neuroptera: Grammolingiidae)
Abstract. Three new species, Grammolingia uniserialis n. sp., Grammolingia binervis n. sp., and Grammolingia sticta n. sp. are described from the Jiulongshan Formation of northeastern China. G. uniserialis n. sp. exhibits a single row of cells in the costal area almost along the entire wing length except the basal part, which is rare in the family and firstly found in this genus. G. binervis n. sp. and G. sticta n. sp. add two new patterns of wing markings to the family. A key to the species of Grammolingia Ren, 2002 is provided. All types of wing markings present in this family are classified.
