Two new species of the genus Yang & Wu, 1994 (Hemiptera: Fulgoroidea: Derbidae) are described from southern China: Lv, Sui & Chen, from Guizhou Province, and Lv, Sui & Chen, from Fujian Province. Detailed morphological descriptions, illustrations, and diagnostic comparisons are provided for both new species, with a particular emphasis on the male genital structures that distinguish them from congeners. A revised identification key to all known species of is also presented. A possible host plant is reported for the first time. The discovery of these taxa expands the known diversity and distribution of the genus in the Oriental region, underscoring the richness of derbid planthoppers in subtropical China.
