Longitarsus fuscoaeneus Redtenbacher, 1849:535 (Type locality: Austria. Lectotype, ΨNHMW, designated here).

Comments. As currently recognized, Longitarsus fuscoaeneus is one of the species of Testergus with the largest geographic range, spanning from Central Europe, Eastern Mediterranean, and Caucasus (including Armenia) to Middle Asia. A number of forms occurring across this range have various degrees of wing reduction but share a similarly shaped median lobe. Some of them were described as subspecies ( Warchalowski 1967). During a visit to the Natural History Museum in Vienna, a female of L. fuscoaeneus was found in the Redtenbacher collection. The genitalia of this specimens are illustrated and this specimen is designated here as a lectotype in order to have a unique bearer of this name and the standard for its application. The specimens is accompanied by a larger label pinned to the bottom of the drawer “Fusco­aeneus Redt.”, labeled with a sign “Ψ”, and the following lectotype label: Lectotype Longitarsus fuscoaeneus Redtenbacher , des. A. Konstantinov 2005.
