Abstract
Two new species of the subfamily Cicadellinae (Hemiptera: Cicadellidae), Atkinsoniella piscioscillum Jiang & Yang, sp. nov., and A. hippocampus Jiang & Yang, sp. nov. from Yunnan, China are described and illustrated. Atkinsoniella piscioscillum Jiang & Yang, sp. nov. is similar to A. yani Yang, Meng & Li, 2017 in appearance, but can be distinguished by the color of the legs, the characteristic of the two longitudinal red stripes on the corium, and the morphology of the male genitalia. Atkinsoniella hippocampus Jiang & Yang, sp. nov. is similar to nine Atkinsoniella species, but can be differentiated by the characteristics of aedeagus and subgenital plate. All type specimens of the two new species are deposited at the Institute of Entomology, Guizhou University, Guiyang, China (GUGC).
