ABSTRACT
A new species of crane fly, Tipula (Pterelachisus) jingkei sp. nov., is described from Beijing, China. The new species is distinguished from related species by the characteristic wing pattern and the structure of the male hypopygium, particularly the nearly truncate caudal margin of tergite 9 bearing two spinous median extensions and a small median spur. Illustrations and detailed morphological descriptions of the adult are provided. This species represents the first record of the subgenus Pterelachisus from Beijing and expands the known diversity of the group in northern China.
