Three new species of the Chinese planthopper genus Tetricodes Fennah (Hemiptera, Fulgoroidea, Issidae, Parahiraciini).

ABSTRACT

The diagnostic characters of the Chinese planthopper genus Tetricodes Fennah, 1956 are redefined. Three new species of this genus, T. ansatus Chang & Chen, sp. n. (China Guangxi), T. parvispinus Chang & Chen, sp. n. (China Guizhou) and T. similis Chang & Chen, sp. n. (China Guizhou) are described and illustrated. The female genitalia of the genus is described and illustrated for the first time. A checklist and key to the species of Tetricodes are given. The synonymy of Tetricodes songae Zhang & Chen, 2009 with Tetricodes polyphemus Fennah, 1956, syn. n., is proposed.
