TYPE GENUS. Selymbria Stål 1861: 615 . Remarks. The genus Selymbria was recently moved from the Taphurini to this new monogeneric tribe ( Marshall et al. 2018 ). The basal position of the genus in the multi-gene tree suggests it is an ancient lineage and it is the only genus of Cicadidae to show similarity in the aedeagus structure to the species of Tettigarcta of the Family Tettigarctidae Distant, 1905f ( Marshall et al. 2018 ). The Selymbriini differ from the other Tibicininae by the supraantennal plate almost meeting the eye, the lack of an accessory auditory structure in the males, the undulated and not right-angled distally aedeagal basal plate, a very short theca that is laterally expanded into a broad flat distal end that is ornamented with triangular wings like species of the Tettigarctidae , and an exceedingly long uncus that is undivided and not retractable within the pygofer ( Marshall et al. 2018 ).
