Holotype , allotype , paratypes 8 $ , 3 , Heilongjiang: Ningan, 5-IX-1988, by Lian Zhenmin and Cao Limin. 2 Podismopsis tesonita, sp. nov. (figs. 6- 8) This new species similar to podismopsis humengensis Zheng &. Lian, but differs from it in elytra of male wide and short,the length larger than width 2. 2-2. 4x; the width of radial area larger than that of subcostal area 2. 5x; each puls group of sound only of two pulses. Female unknown. Length of body: 17-19mm; length of pronotum 3-3. 5mm; length of elytra: 11- 11.5mm; length of hind femur 11. 5- 12. 5mm.

Length of body: 18mm, 25-28mm. Length of pronotum: 4mm, 5-5. 5mm. Length of elytra- 11.5mm, 3. 5-4mm. Length of hind femur. 13.5mm, 14-15mm. Holotype , allotype , paratypes 2 , Heilongjiang.
