Abstract: Two new monotypic genera of flatid planthoppers (Hemiptera: Fulgoromorpha: Flatidae) are described from Socotra island (Yemen): Dixamflata gen. nov. for D. petri sp. nov. and Kesaflata gen. nov. for K. lubosi sp. nov. Habitus, male and female external and internal genital structures of the new species are illustrated and compared to similar taxa. Both new genera share an “issid-like” habitus which evolved convergently in many unrelated planthopper groups distributed in arid and semi-arid zones of the world. They might be closely related to the western Palaearctic genera Cyphopterum Melichar, 1905 and Riodeorolix Lindberg, 1956. As both new species are sub-brachypterous and were collected in plant communities specific to Socotra, they may represent endemics of the island.
