Abstract
The Oriental dictyopharid planthopper genus Tenguna, Matsumura, 1910 is redescribed, including its type species and a new species: Tenguna medogensis sp. nov. (S.W. China: Xizang). The discovery of the new species broadens our knowledge of the morphology and biogeography of the genus Tenguna and also represents the first record of the planthopper family Dictyopharidae in Xizang Autonomous Region, P. R. China.
