Abstract: The Neotropical genus Pygodiscodon Wittmer, 1966 (Coleoptera: Cantharidae: Silinae: Silini) is revised. Six species are recognized as valid, three of which are herein proposed as new: Pygodiscodon apicicornis (Pic, 1910), P. gurupi sp. nov., P. monoceros sp. nov., P. obscurus Wittmer, 1966, P. similis sp. nov., and P. touroulti Constantin, 2010. Pygodiscodon obscurus, currently synonymized with P. apicicornis, is herein revalidated. A lectotype is designated for P. apicicornis. Pygodiscodon apicicornis and P. touroulti are recorded for the first time in Guyana and Suriname, and Brazil respectively. An identification key and a distributional map for the species are provided.
