Abstract

Two new genera, Tardivena Wang & Bourgoin gen. nov. and Platyclamys Wang & Bourgoin gen. nov., of the fossil planthopper family Yetkhatidae are described from mid-Cretaceous Myanmar amber, based respectively on the type species Tardivena multiradiata Wang & Bourgoin sp. nov. and Platyclamys angulata Wang & Bourgoin sp. nov. A revised key to the genera of Yetkhatidae is provided. The new taxa expand the known morphological disparity of the family and refine several diagnostic characters, particularly in head structure, thoracic carinae, and forewing venation. These findings improve the delineation of Yetkhatidae and contribute new information to the understanding of morphological evolution within early Fulgoroidea.
