Notes. Pardogryllacris was established as a genus by Karny in 1937, and treated as a subgenus of Gryllacris by Ingrisch in 2018, containing 6 species and 2 subspecies distributed in Southeast Asia and Sri Lanka. After checking the holotype of this species, we discovered the characteristics of this specimen that consist with Pardogryllacris : fastigium verticis as wide as scapus ( Fig. 7B ); cross-veins of forewings dark in color ( Fig. 7A ); the subgenital plate wide at base area, while posterior area narrows greatly and is concave upwards in semi-cylindrical shape with truncate terminus ( Fig. 7C ); a narrow elongate flap emerges at the middle part of the subgenital plate, concave upwards towards the posterior area ( Fig. 7D ). These factors strongly indicate that this species belongs to Gryllacris (Pardogryllacris) , instead of Haplogryllacris .

Distribution. Only known distributed from China.
