The genus Hadoa comprises large-bodied Cicadidae occurring in Western North America. Until recently, these species were in the genus Tibicen (now genus Lyristes Horvath, 1926),{{cite journal |last1=International Commission on Zoological Nomenclature |title=Opinion 2475 (Case 239) – Tibicina Kolenati, 1857 and Lyristes Horvath, 1926 (Insecta, Hemiptera): usage conserved by the suppression of Tibicen Berthold, 1827; Cicada Linnaeus, 1758 (Insecta, Hemiptera): usage conserved by designation of Cicada orni Linnaeus, 1758 as the type species|journal=Bulletin of Zoological Nomenclature |date=2021 |volume=78 |issue=2 |pages=138–141 |doi=10.21805/bzn.v78.a032 |url=https://www.biotaxa.org/bzn/article/view/70708}} which has now been redefined so as to include only a few European species, while most species from the Eastern and Central US are now placed in Neotibicen and Megatibicen.{{cite journal |author=Kathy B R Hill|display-authors=et.al.|title=Molecular phylogenetics, diversification, and systematics of Tibicen Latreille 1825 and allied cicadas of the tribe Cryptotympanini, with three new genera and emphasis on species from the USA and Canada (Hemiptera: Auchenorrhyncha: Cicadidae)|journal=Zootaxa|year=2015|volume=3985|issue=2|pages=219–251 |doi=10.11646/zootaxa.3985.2.3|doi-access=free|pmid=26250031 }}
