TL;DR: A cladistic analysis of generic relationships has been used to test the validity of currently held views on family and subfamily groupings, based upon an exhaustive study of nymphal and adult morphology, including both external and internal adult structures.
Abstract: The history of cicada family classification is reviewed and the current status of all previously proposed families and subfamilies summarized. All tribal rankings associated with the Australian fauna are similarly documented. A cladistic analysis of generic relationships has been used to test the validity of currently held views on family and subfamily groupings. The analysis has been based upon an exhaustive study of nymphal and adult morphology, including both external and internal adult structures, and the first comparative study of male and female internal reproductive systems is included. Only two families are justified, the Tettigarctidae and Cicadidae. The latter are here considered to comprise three subfamilies, the Cicadinae, Cicadettinae n.stat. (= Tibicininae auct.) and the Tettigadinae (encompassing the Tibicinini, Platypediidae and Tettigadidae). Of particular note is the transfer of Tibicina Amyot, the type genus of the subfamily Tibicininae, to the subfamily Tettigadinae. The subfamily Plautillinae (containing only the genus Plautilla) is now placed at tribal rank within the Cicadinae. The subtribe Ydiellaria is raised to tribal rank. The American genus Magicicada Davis, previously of the tribe Tibicinini, now falls within the Taphurini. Three new tribes are recognized within the Australian fauna, the Tamasini n.tribe to accommodate Tamasa Distant and Parnkalla Distant, Jassopsaltriini n.tribe to accommodate Jassopsaltria Ashton and Burbungini n.tribe to accommodate Burbunga Distant. Additional tribal changes occur within the Australian fauna: Anapsaltoda Ashton, Arenopsaltria Ashton, Henicopsaltria Stal, Neopsaltoda Distant and Psaltoda Stal are transferred from Cyclochilini to Cryptotympanini leaving Cyclochilini monotypic; Chrysocicada Boulard is transferred from Parnisini to Taphurini; Diemeniana Distant, Gudanga Distant and Quintilia infans (Walker) (representing a new genus) from Parnisini to Cicadettini; and Marteena Moulds and Abricta borealis (Goding & Froggatt) (the latter also representing a new genus) from Taphurini to Cicadettini. A new subtribe is proposed in the tribe Taphurini, Tryellina n.subtribe. Diagnostic descriptions are provided for all families, subfamilies, tribes and subtribes treated in this work. Keys to families and subfamilies are presented together with a key to the tribes of Australian Cicadoidea. Terminologies for external and internal morphology of the Cicadoidea are summarized in 30 detailed figures. New structures and features of significant taxonomic importance are identified and named. A stridulatory mechanism found in the Australian genus Cyclochila is described for the first time.

TL;DR: The cicada genus Abricta Stål is here redefined to include just two species that are found only in Mauritius, and the genus Chrysolasia n.gen.
Abstract: The cicada genus Abricta Stål currently contains a heterogeneous group of species which is considered best divided into four genera. Abricta sensu str. includes only A. brunnea (Fabricius) and A. ferruginosa (Stål) which are confined to Mauritius and neighbouring islands. The monotypic genus Chrysolasia n.gen., is proposed for a single Guatemalan species, A. guatemalena (Distant). Another monotypic genus, Aleeta n.gen., is proposed for the species A. curvicosta (Germar) from eastern Australia. Fourteen Australian species are placed in Tryella n.gen.: castanea Distant, noctua Distant, rubra Goding & Froggatt, stalkeri Distant, willsi Distant, adela n.sp., burnsi n.sp., crassa n.sp., graminea n.sp., infuscata n.sp., kauma n.sp., lachlani n.sp., occidens n.sp. and ochra n.sp. The five remaining species currently placed in Abricta (borealis Goding & Froggatt, burgessi Distant, cincta Fabricius and occidentalis Goding & Froggatt from Australia plus pusilla Fabricius of unknown locality) do not belong to Abricta or closely allied genera. Cladistic analyses place C. guatemalena basally on all trees. The Mauritian genus Abricta sensu str., and the genera, Abroma Stål and Monomatapa Distant, form a sister group to all Australian species. There is strong evidence suggesting that Abricta and Abroma are synonymous. Keys to genera and species and maps of distribution are provided. MOULDS, M.S., 2003. An appraisal of the cicadas of the genus Abricta Stål and allied genera (Hemiptera: Auchenorrhyncha: Cicadidae). Records of the Australian Museum 55(3): 245–304. Records of the Australian Museum (2003) Vol. 55: 245–304. ISSN 0067-1975 www.amonline.net.au/pdf/publications/1386_complete.pdf The genus Abricta belongs to the tribe Taphurini and previously included 14 described species distributed through Australia, Mauritius, and Guatemala. The largest of these, A. ferruginosa (Stål) from Mauritius, attains a wingspan of over 100 mm while the smallest, now Tryella castanea (Distant) from Australia, has a wingspan of around 45 mm. The historical review below shows that species of Abricta have been described on an ad hoc basis with no real assessment of generic limits. Many of the species descriptions lack detail and some important morphological characters have never been examined. Perusal of museum specimens suggested that Abricta was not be a coherent generic group and highlighted many difficulties in identifying Australian specimens. Abricta Stål is here redefined to include just two species that are found only in Mauritius. The genus Chrysolasia n.gen. is established to accommodate the single Guatemalan species. Two genera are erected for the Australian species: Aleeta n.gen. which includes curvicosta Germar only, while the remainder are placed in Tryella n.gen. Nine new species of Tryella are described from Australia, making a total of 14. It has been necessary to place considerable emphasis
