Abstract: This paper describes two new species of leafhoppers injurious to Bamboo. 1. Bambusana brancha sp. nov. Body length (incl. tegm.): ♂5.5～5.7 mm，♀5.8～6.0 mm.Holotype ♂,Kuankuoshui, Guizhou Prov., 1-5,Aug.1984coll.by Li Zizhong; Paratypes 8♂♂，17♀♀，same data as holotype; 11♂♂，25♀♀，Fanjingshan,Guizhou Prov.,11-14Aug.1994, coll.by Chen Xiangsheng.Host plant: Phyllostachys heterolado Oliv.This new species is similar to Bambusana bambusae (Matsumura,1914) in appearance,but can be distinguished from latter by the ventral margin of pygofer side at apex indentationlike and its middle with one branchlike process,the apex of aedeagua forked. 2. Bambusana leigongshana sp. nov. Body length (incl. tegm.): ♂4.0～4.2 mm，♀4.8～5.0 mm. Holotype♂, Leigongshan,Guizhou Prov.,1-2 June. 2005 coll.by Li Zizhong and Zhang Bin; Paratypes 5♂♂，2♀♀，same data as holotype. Host plant: Chimonobambus angustfolia C. D. Chu et C. S. Chao.This new species is allied to Bambusana jenjouristi (Anufriev,1969) in appearance,but can be distinguished from latter by the ventral margin of pygofer side indentation-like,and pygofer side without a serrated protrusion subapically on ventral margin, aedeagus shaft without a ventro-basal tooth-like process.The type specimens are deposited in the Institute of Entomology,Guizhou University.
