Three new species of Atkinsoniella (Hemiptera, Cicadellidae, Cicadellinae) from southwestern China

Three new species of the genus <i>Atkinsoniella</i> (Hemiptera: Cicadellidae: Cicadellinae), <i>A.chongqingana</i> Jiang & Yang, <i>A.likuni</i> Jiang & Yang and <i>A.biostiolum</i> Jiang & Yang, <b>sp. nov.</b>, collected from southwestern China, are described and illustrated. The two new species, <i>A.chongqingana</i> Jiang & Yang, <b>sp. nov.</b> and <i>A.likuni</i> Jiang & Yang, <b>sp. nov.</b>, are similar to <i>A.nigrominiatula</i> (Jacobi, 1944), <i>A.latior</i> Young, 1986, <i>A.limba</i> Kuoh, 1991, <i>A.dormana</i> Li, 1992, <i>A.divaricata</i> Yang, Meng & Li, 2017, <i>A.peaka</i> Yang, Meng & Li, 2017, and <i>A.zizhongi</i> Jiang & Yang, 2022 in appearances, but can be distinguished from these species by the characteristic of aedeagus, paraphysis, and pygofer. <i>Atkinsonellabiostiolum</i> Jiang & Yang, <b>sp. nov.</b> can be distinguished from all the known <i>Atkinsoniella</i> species by its special color and markings, as well as males having one ostiole in the center of the base of each subgenital plate. A key to <i>Atkinsoniella</i> species from China is provided.
