Tibicininae Distant 1905

Subfamily Tibicininae Distant, 1905d REMARKS. The Tibicininae can be distinguished by the metanotum being entirely concealed on the dorsal midline, fore wing cubitus posterior and anal vein 1 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 the posterior margins of the tympanal cavities, males without abdominal timbal covers or with partially recurved rim, the male pygofer with an undeveloped distal shoulder, pygofer upper lobes absent (present only in the Selymbriini Moulds and Marshall, 2018 (in Marshall et al. 2018)), very long and non-retractable uncus within the pygofer, claspers absent, aedeagus with a ventrobasal pocket, restrained by tubular encapsulation below uncus, and apical theca with a pair of leaf-like lateral lobes (Marshall et al. 2018). Tribe Selymbriini Moulds and Marshall, 2018 (in Marshall et al. 2018) Selymbriini Moulds and 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 two extant species of Tettigarcta of the Family Tettigarctidae Distant, 1905f (Marshall et al. 2018). The Selymbriini differ from the other Tibicininae tribes by the supra-antennal 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).Published as part of Sanborn, Allen F., 2019, The cicadas (Hemiptera: Cicadidae) of Bolivia including the descriptions of fifteen new species, the resurrection of one genus and two species, seven new combinations, six new synonymies, and twenty-eight new records, pp. 1-104 in Zootaxa 4655 (1) on page 91, DOI: 10.11646/zootaxa.4655.1.1, http://zenodo.org/record/336584
