Vietanna Lee & Pham, gen. nov. and Vietanna hanoiensis Pham & Lee, sp. nov. are described based on a cicada specimen from Hanoi, Vietnam and placed in the subtribe Leptopsaltriina Moulton, 1923 of the tribe Leptopsaltriini Moulton, 1923 in the subfamily Cicadinae Latreille, 1802 (Hemiptera: Cicadidae). This new genus is morphologically similar to Tanna Distant, 1905 but distinguished from Tanna by the timbal cover exposing the inner part of timbal, the male abdominal epipleurite 3 with a distinct oblique linear fold, the male abdominal sternites without tubercle-like projections, and the aedeagus bifurcate at the apex. A key to the genera of Leptopsaltriina is provided.
