| Abstract: | Chinese species in the genus Nycheuma Fennah, 1964a (Hemiptera: Fulgoromorpha: Delphacidae: Delphacinae: Delphacini) are revised to include three species: Nycheuma
cognatum (Muir, 1917), Nycheuma
dimorpha (Matsumura, 1910) and Nycheuma
nilotica Linnavuori, 1973. Nycheuma
coctum Yang, 1989 is placed in synonymy with Nycheuma
nilotica Linnavuori, 1973. Nycheuma
dimorpha (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. |
