- Subfamily Tibicininae Distant, 1905a REMARKS. Species of the Tibicininae can be distinguished by the metanotum being entirely concealed on the dorsal midline, the fore wing cubitus posterior and anal vein 1 are unfused (except in the Platypediini Kato, 1932), hind wing radius posterior and median veins unfused at their bases, male opercula distinctively S-shaped with deeply concave lateral margin not reaching posterior margins of tympanal cavities (except in the Selymbriini Moulds & Marshall, 2018 (in Marshall et al. 2018)), males without abdominal timbal covers or with partially recurved rim, the male pygofer exhibiting undeveloped distal shoulder, pygofer upper lobes absent (present in some of the Selymbriini), uncus very long, non-retractable within pygofer, claspers absent, aedeagus with ventrobasal pocket, restrained by a tubular encapsulation below uncus, apical theca with a pair of leaf-like lateral lobes (Moulds 2005; Marshall et al. 2018). Tribe Selymbriini Moulds & Marshall, 2018 (in Marshall et al. 2018) Selymbriini Moulds & Marshall 2018 (in Marshall et al. 2018): 53. 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 White, 1845 of the Family Tettigarctidae Distant, 1905d (Marshall et al. 2018). The Selymbriini differ from the other Tibicininae by the supra-antennal plate almost meeting the eye, the lack of an accessory auditory structure in the males, the male opercula generally covering the tympanal cavity completely, the distal aedeagal basal plate is undulated rather than right-angled, the very short theca is laterally expanded into a broad, flat distal end ornamented with triangular wings similar to species of the Tettigarctidae, pygofer upper lobes usually present, and an exceedingly long, undivided uncus that is not retractable within the pygofer (Marshall et al. 2018). GENERA INCLUDED. The tribe is represented currently only by the genus Selymbria Stål, 1861.
