description: Key to Chinese species of genus Pedionis based on male penis
So far, 14 species of genus Pedionis (all in nominate subgenus P. (Pedionis )), including 3 new species described in the present work, are known in China. According to original descriptions, illustrations and examinations of specimens the following key based on the male aedeagus appears to distinguish Chinese Pedionis species, and is updated from the previous Chinese key by Zhang & Viraktamath (2010) and the worldwide key by Li et al. (2011) to include the species described herein and P. (P.) sagittata Dai, Li et Li, 2011.
