03E49D6B453EFFE325D1FC5CFA91FEEC.taxon	etymology	Etymology. The genus name is a combination of “ Li ” and “ delphax ”, in honor of Professor Zi-Zhong Li at Guizhou University, a Chinese entomologist who specializes in Hemiptera.	en	Lv, Shasha, Long, Jiankun, Chang, Zhimin, Zhang, Yubo, Feng, Xiao, Du, Maoheng, Chen, Xiangsheng, Yang, Lin (2026): New genus and new species of Vizcayinae (Hemiptera, Fulgoromorpha, Delphacidae) from Guizhou Province in China.

03E49D6B453EFFE325D1FC5CFA91FEEC.taxon	discussion	Remarks. This new genus is closely related to Neovizcaya Liang, 2002, but differs from the latter in: (1) head narrow, a little protruding in front of eyes (head very broad, well protruding in front of eyes in Neovizcaya); (2) vertex without an shaped ridge on posterior half and indistinct Y-shaped ridge on posterior half (vertex with an shaped ridge on posterior half and indistinct Y-shaped ridge on posterior half in Neovizcaya); (3) frons normal (frons very broad in Neovizcaya); (4) antenna extremely elongate, apex of pedicel reaching base one quarter of forewings in response (antenna moderately elongate, apex of pedicel reaching base of forewings in response in Neovizcaya); (5) aedeagus with two long spinose processes (aedeagus with three short spinose processes in Neovizcaya).	en	Lv, Shasha, Long, Jiankun, Chang, Zhimin, Zhang, Yubo, Feng, Xiao, Du, Maoheng, Chen, Xiangsheng, Yang, Lin (2026): New genus and new species of Vizcayinae (Hemiptera, Fulgoromorpha, Delphacidae) from Guizhou Province in China.
