Abstract
The cixiid planthoppers genus Neocarpia Tsaur & Hsu, 2003 is reviewed. Two new species, N. acutata Zhi & Chen, sp. n. and N. reversa Zhi & Chen, sp. n., are described and illustrated from the southwest of China (Yunnan) to give the genus seven species in total. Female genitalia of four Chinese species are described and illustrated for the first time. A key to all known species of Neocarpia based on male genitalia, and a key to Chinese species (except for N. maai) based on female genitalia, are provided. The morphological characteristics of the posterior vagina, utilized to distinguish female species of Neocarpia, are also discussed.
