Bambusicaliscelis Chen & Zhang gen. nov. (Hemiptera: Fulgoroidea: Caliscelidae: Caliscelinae: Caliscelini) is established to accommodate two new species, Bambusicaliscelis fanjingensis Chen & Zhang, sp. nov. (type species, Guizhou, southwestern China) and B. dentis Chen & Zhang, sp. nov. (Guizhou, southwestern China). Members of the new genus are known to feed exclusively on bamboo (Poaceae: Bambusoideae) and represent the first record of bamboo-feeding planthopper Caliscelidae in China. The main morphological features, male genitalia, and the fifthinstar nymphs of two new species are described and illustrated. In addition, photographs and a key for identifying the adults and fifth-instar nymphs of the genus Bambusicaliscelis are provided. The importance of those groups as a pest on bamboo is discussed briefly. Biological notes and a discussion of those groups' distribution are given.
