VII. 1993, collected by Chen Jun.Sinopodisma sunzishanensis sp. nov. (figs. 6￣12)This new species is allied to Sinopodisma kellogii(Chang)and Sinopodisma quizhouensis Zheng.

Length of elytra:2. 5￣3 mm;3. 5￣4 mm. Length of hind femur:10￣11mm;13￣15 mm.Holotype,allotype,Sichuan: Gulin (Sunzishan), 23. VII.1993, 1100-1300 m,collected by Chen Jun; paratypes 17,11, Sichuan: Gulin (Sunzishan),20￣23.VII. 1993,1100￣1750 m, collected by Chen Jun and Shi Fumin.Pseudoptygonotus jinshaensis sp. nov.
