Still greater disparity in basal planthopper lineage: a new planthopper family Yetkhatidae (Hemiptera, Fulgoromorpha, Fulgoroidea) from mid-Cretaceous Myanmar amber

Abstract A new family Yetkhatidae Song, Szwedo et Bourgoin fam. nov. from mid-Cretaceous amber of Myanmar is described. It is characterized by the tegmina with a triangular basal cell and in having the apex of the clavus closed, the female genitalia with robust endogonocoxal processes, the head capsule with trigones and foliated frontal margins, ridged lora (visible frontally) and by intermediate carinae on the mesonotum. Two new monotypic genera are described in this new family: Yetkhata Song, Szwedo et Bourgoin gen. nov., with Yetkhata jiangershii Song, Szwedo et Bourgoin sp. nov. and Parwaina Song, Szwedo et Bourgoin gen. nov. with Parwaina liuyei Song, Szwedo et Bourgoin sp. nov. A key to recognition of these genera is provided, and their morphological characters and disparity are briefly discussed.
