A new species Euchorthippus fusigeniculatus, collected from Changbai Mountains, Jilin Province has been described and illustrated. This new species is allied to Eu. cheui Hsia, but differs from the latter in: 1) lateral carinae of the pronotum weakly incurved in the prozona, 2) the hind femora with dark knees, 3) the sides of supra-anal plate in the male with brown carinae.
