Planthoppers are insect of the infraorder Fulgoromorpha, which consists of some 12,500 described species worldwide. The name comes from their resemblance to leaves and other plant parts and from the fact that they often jump for quick transportation in a similar way to that of grasshoppers.
Planthoppers are feeding on plant sap and are therefore often vectors for plant diseases that can be transmitted in the process.
The new species was named after the type locality, Guangxi province, in China.
For the experts: The planthopper genus Neohemisphaerius Chen, Zhang & Chang, 2014 (Hemiptera: Fulgoroidea: Issidae) is reviewed to include 3 species: N. wugangensis Chen, Zhang & Chang, 2014 (China: Hunan), N. yangi Chen, Zhang & Chang, 2014 (China: Guangdong) and N. guangxiensis sp. n. (China: Guangxi). A revised generic diagnosis is given. The new species is described and all species illustrated. A key to these three species is also given. The species Neohemisphaerius signifer (Walker) is transferred back to Hemisphaerius as H. signifer Walker, comb. revived.
