Opsiini
Opsiini is a tribe of leafhoppers in the subfamily Deltocephalinae, established by Emeljanov in 1962. The tribe comprises approximately 36 genera and over 300 species, organized into four subtribes: Achaeticina, Circuliferina, Eremophlepsiina, and Opsiina. Members are distributed across the Palearctic and Oriental regions, with particular diversity in arid and semi-arid zones of Central Asia and China. Several species groups within Opsiini have been subject to intensive taxonomic revision due to cryptic species complexes distinguishable primarily by male vibrational acoustic signals rather than morphology.
