Proposed designation of a neotype for Issus longipennis Spinola, 1839, the type species of Thionia Stål, 1859 (Hemiptera: Auchenorrhyncha: Fulgoroidea: Issidae)

Abstract. Following the ICZN (1999) Articles 75.1–75.3, a neotype of Issus longipennis Spinola, 1839 is designated. This leads to the synonymy of Issus longipennis Spinola, 1839 and Issus cinctifrons Stål, 1854, syn. nov. and stabilization of the generic concept of Thionia Stål, 1859, one of the largest genera in the family Issidae which currently includes 62 species.
Key words: nomenclature, systematics, Fulgoroidea, Issidae, Thionia, Thionia longipennis, Thionia cinctifrons
