The raphidiopteran fauna of Xinjiang in northwestern China is poorly known, although it is near Central Asia where the diversity of this group is high. Herein we report a new species and a new Chinese record of the raphidiid genus Mongoloraphidia H. Aspck U. Aspck, 1968 from Xinjiang, namely Mongoloraphidia xinjiangana sp. nov. and Mongoloraphidia (Mongoloraphidia) kaszabi (H. Aspck U. Aspck, 1967), respectively. A key to the identification of the Mongoloraphidia species from China is provided.
