Two new kalligrammatids (Insecta, Neuroptera) from the Middle Jurassic of Daohugou, Inner Mongolia, China

A new genus and two new species of kalligrammatid lacewings (Insecta, Neuroptera), Kalligramma paradoxum sp. nov. and Huiyingogramma formosum gen. et sp. nov., are described and figured, based on two well-preserved forewings from the Middle Jurassic of Daohugou, Inner Mongolia, China. Kalligramma paradoxum sp. nov. can be distinguished from other known Kalligramma species based on forewing characters (e.g., wing shape, costal space, branches of Rs, eye-spot). Huiyingogramma gen. nov. is characterized by a distinct humeral recurrent vein, relatively broad costal space with well-forked costal veinlets, well-developed eye-spot and dense crossveins over the entire wing.
