Abstract
Three new species of the genus Thapaia Dmitriev & Dietrich, 2006 (Hemiptera: Cicadellidae: Typhlocybinae) are described and illustrated: T. cavitrigona, T. elongata, and T. jinghongensis spp. nov. Specimens were collected from Thailand and China. Detailed morphological descriptions, illustrations of male genitalia, and habitus photographs are provided for each new species. A revised key to males of all known species worldwide is compiled to facilitate identification. The main differences between the new species and other congeneric species lie in the unique characteristics of the male genitalia, including the morphology of the aedeagal shaft, dorsal atrium, and dorsal pygofer appendages. Type specimens from China are deposited in the School of Karst Science, Guizhou Normal University, Guiyang, China (GZNU). Holotypes of species described from Thailand are deposited in the Queen Sirikit Botanical Garden, Chiang Mai, Thailand (QSBG).
