Abstract: The Nearctic leafhopper species Gyponana (Gyponana) mali DeLong, 1942 is reported from Europe for the fi rst time and represents the fi rst record of the tribe Gyponini Stål, 1870 (Hemiptera: Cicadellidae: Iassinae: Gyponini) for the Palearctic Region. Specimens were collected in southern Switzerland (Ticino) and two regions of northern Italy (Lombardy and Veneto) in 2015–2019. The preferred host plant in these areas appears to be Cornus sanguine L. Phylogenetic analysis of the COI barcode sequences grouped one of the European specimens with three individuals of G. (G.) mali from Ontario, Canada. Morphological study indicated that the male genitalia of the European population are intermediate between G. (G.) mali and G. (G.) extenda DeLong, 1942.
