Abstract
A new specimen of the species Litholingia rhora Ren, 2002, from the Middle-Upper Jurassic deposit of Daohugou, is used to redescribe the species and precise its diagnosis. We also propose a series of wing venation drawings highlighting the main characteristics of the wing venation all Litholingia species. Finally, we summarize the current diversity of the lacewing family Grammolingiidae.
