Many Jurassic fossil nemestrinid Mes have been found in the Palaearctic region. China is an important locality for fossil pemestirinid flies. Up to now, 2 genera with 3 species have been discovered in China. In the present paper, a third genus and species, Ahirmoneura neimengguensis Zhang, Yang, and Ren, gen. et sp. nov., from the Middle Jurassic Daohugou Formation of China is described. A key to genera of fossil nemestrinid flies from China is given.
