Tibicen
Tibicen is a suppressed genus name in the cicada family Cicadidae, officially rejected by the International Commission on Zoological Nomenclature in 2021. Originally published by Latreille in 1825 and made available by Berthold in 1827, the name was applied to over 100 cicada species across the Northern Hemisphere during the 20th century, particularly to North American dog-day cicadas. Longstanding nomenclatural controversy centered on whether the original publications validly established the genus, with competing type species designations creating taxonomic confusion. The 2021 suppression placed Tibicen on the Official Index of Rejected and Invalid Generic Names in Zoology. Former European species now reside in genus Lyristes, while North American and Asian species have been reassigned to genera including Neotibicen, Megatibicen, Auritibicen, and Hadoa.
