Abstract
Four new species of the genus Andes Stål, 1866 (Hemiptera, Auchenorrhyncha, Fulgoromorpha, Cixiidae, Cixiinae, Andini) are described from China: A. cuneatus Lv, Zhi & Chen, sp. nov., A. luchunensis Lv, Zhi & Chen, sp. nov., A. scalpratus Lv, Zhi & Chen, sp. nov. from Yunnan Province, and A. orbiculatus Lv, Zhi & Chen, sp. nov. from Fujian Province. Detailed morphological descriptions, illustrations including female terminalia, and diagnostic comparisons are provided for all new species, with a particular emphasis on the male genital structures that distinguish them from congeners. An updated identification key to all known Chinese species of Andes is also presented.
