The first cixiid planthopper (Fulgoromorpha: Cixiidae) from Lower Cretaceous Jinju Formation (Republic of Korea)
• The first planthopper fossil is described from the Cretaceous Jinju Formation. • The fossil is assigned to the diverse family of Cixiidae based on diagnostic morphological characters. • Affinities with all extinct and extant cixiid lineages are discussed • This new occurence extend the Lower Cretaceous fossil record of the family into Asia. A new extinct genus and species of Cixiidae are described as Jinjucixius fui gen. et sp. nov. from the Lower Cretaceous of Jinju Formation (Republic of Korea). This new taxon is one of the earliest representatives of Cixiidae and extends the fossil record of the family to this outcrop, being the first Fulgoromorpha described from this formation. The description of this new taxon allowed us to discuss the phylogenetic relationships between cixiid lineages.
