Abstract: This study documents six species of the genus Tambana Moore, 1882 from southeastern Xizang, China. Among these species, T. albiplaga (Warren, 1912) is recorded from China for the first time and represents a new national record. T. entoxantha (Hampson, 1894), T. subflava (Wileman, 1911) and T. arctoides Speidel & Kononenko, 1998 are recorded from Xizang for the first time and constitute new provincial records. T. indeterminata Behounek, Han & Kononenko, 2015 and T. variegata Moore, 1882 are previously known from Xizang. Morphological descriptions are provided for the adults of all six species, as well as for their genitalia. High-resolution color images of the adults and genitalia are presented, supplemented with updated information on the species’ distribution both within China and worldwide.

Keywords: genitalia, newly recorded species, Tambana, taxonomy
