An extraordinary ‘nogodinid’ planthopper (Hemiptera: Fulgoroidea) from the earliest Eocene Fur Fm. of Denmark

The Ypresian Fur Formation in northwestern Denmark is one of the most famous and important sources of insect fossils from the early Eocene (ca. 55–54 Ma, Pedersen et al., 2012; Madsen & Rasmussen, 2021). The first insect fossils from the formation were described more than 100 years ago by Henriksen (1922), and today approximately 100 species have been described from more than 20,000 known fossils (TJS, JAR, RLS pers. observ.). Although the hemipteran suborder Auchenorrhyncha (cicadas, leafhoppers, planthoppers and allies) comprise one of the major components of this massive body of fossils (Rust, 1999; pers. unpublished obs.) only six species have been formally described to date. Of these the most recently described species, Archerythrogonia furensis Dietrich & Perkovsky, 2023 belongs to the infraorder Cicadomorpha (Dietrich & Perkovsky, 2023). The remaining five species all belong to the infraorder Fulgoromorpha (Szwedo et al., 2004).
