Abstract
Chinese species in the genus Nycheuma Fennah, 1964a (Hemiptera: Fulgoromorpha: Delphacidae: Delphacinae: Delphacini) are revised to include three species: Nycheumacognatum (Muir, 1917), Nycheumadimorpha (Matsumura, 1910) and Nycheumanilotica Linnavuori, 1973. Nycheumacoctum Yang, 1989 is placed in synonymy with Nycheumanilotica Linnavuori, 1973. Nycheumadimorpha (Matsumura, 1910) is newly recorded from China. The generic characteristics are redefined. The main morphological characters, male genitalia of 3 species are described or redescribed and illustrated. A key to Chinese species in the genus is provided.
