Abstract
The second genus and species of the planthopper family Katlasidae, Dumpyawnus hpungwanus gen. et sp. nov., is described from mid-Cretaceous Kachin (Burmese) amber. It can be definitely attributed to Katlasidae mainly based on its tegminal structure (e.g., costal area absent, clavus closed, tegmen widened at membrane, multiplied forked of ScP + RA, MP and CuA2, single CuA1, nodal line absent) and hind wing venation (e.g., ScP + RA, RP, MP and CuA with 3–5 terminals), but the new genus is clearly different from Katlasus Luo, Jiang et Szwedo, 2020, the type genus of Katlasidae, according to its wing venation (e.g., terminals of ScP + RA usually forked, MP with less terminals). The morphological features and placement of the new taxon are briefly discussed.
