A new genus and species of snakefly, Laiyangoraphidia delicata gen. et sp. nov., is described from the Lower Cretaceous Laiyang Formation, eastern Shandong, China. This is another genus characterised by the short pterostigma in Mesoraphidiidae. Its complex branching structure and the absence of crossveins between and inside RP and MA suggest it may be a transitional taxon between Grammoraphidia and Proraphidia. This discovery enriches our knowledge on the biodiversity of Raphidioptera from the Lower Cretaceous Laiyang Formation.
