New changes to the classification of the North American cicadas belonging to the genus Cicadetta have been published. The North American Cicadetta were found to be unrelated to the European Cicadetta (including the type species C. montana), so a new genus was needed. The new genus is Cicadettana. Research & paper by David Marshall and Kathy Hill.

The generic classification of cicadas within the globally distributed tribe Cicadettini (Hemiptera: Cicadidae) has been challenging due to their often conservative morphology. A recent molecular analysis has indicated that the six North American taxa currently classified in Cicadetta are unrelated to the European type species of Cicadetta, C. montana Scopoli. Here we identify a set of diagnostic morphological characters for a new genus, which we distinguish from its closest relatives in Eurasia and Australasia.
