Abstract

Homocopris Burmeister, 1846 (Coleoptera: Scarabaeidae) is a small genus of South American dung beetles composed of four species distributed in Argentina, Brazil, and Chile. Recently, a neotype was des¬ignated for Copris torulosus Eschscholtz, 1822 (currently H. torulosus) based on the assumption that the original type series had been lost. However, this designation is invalid for failing to comply with articles 75.2, 75.3, 75.3.1, and 75.3.4. of the International Code of Zoological Nomenclature. Furthermore, even if it had been nomenclaturally valid, the neotype now loses its type status because we found a syntype in the material of the Johann Friedrich Eschscholtz collection, preserved in the collection of Zoological Museum, Moscow Lomonosov State University, Moscow, Russia. We present evidence supporting the recognition of this speci-men as a syntype and newly designate it as the lectotype. Photographs of the lectotype and its labels are provided. Additionally, the geographic distributions of H. punctatissimus (Curtis, 1844) and H. torulosus (Eschscholtz, 1822) in Chile are corrected.
