Case 3879 – Tachina viridis Fallén, 1810 (currently Gymnocheta viridis; Insecta, Diptera, Tachinidae): proposed conservation of current usage by designation of a neotype

Abstract

Abstract. The purpose of this application, under Article 75.6 of the Code, is to conserve the current usage of the combination Gymnocheta viridis (Fallén, 1810) for a species of Palaearctic tachinid fly by setting aside the existing holotype of Tachina viridis Fallén, 1810 and designating a neotype in its place. The holotype is not in taxonomic accord with the current usage of the name Gymnocheta viridis and is instead conspecific with the lectotype of Gymnocheta magna Zimin, 1958. Stability and universality will be threatened if the existing holotype of Gymnocheta viridis is not replaced by a neotype, because Gymnocheta viridis will become the valid name for Gymnocheta magna and a replacement name will be needed for the current Gymnocheta viridis.
