A new species of Kalligramma Walther, 1904 (Insecta, Neuroptera, Kalligrammatidae) from the Middle-Upper Jurassic of Daohugou, Inner Mongolia, China

A new species of Kalligramma Walther, 1904 (Insecta, Neuroptera, Kalligrammatidae) is described as Kalligramma delicatum based on a nearly complete forewing from the Middle-Upper Jurassic of Daohugou, Inner Mongolia, China. The new species is characterized by the narrow costal space with sinuous costal veinlets, Rs with eight primary branches, MP with five pectinate branches and 1A forked beyond its mid-length. The forewing of Kalligramma can be distinguished from the hind wing by its ovate rather than subtriangular shape, significantly wider costal space and more numerous crossveins between costal veinlets. The new species is interpreted to represent a forewing based mainly on its shape.
