Cyparium, the only genus of the tribe Cypariini, comprises 62 species, 5 subspecies, and one “potential new species”, with the majority occuring in the Neotropical Region (23 spp. and 3 subspecies), of which 13 are from Brazil (Löbl 2018; von Groll & Lopes-Andrade 2021; Löbl & Cosandey 2023). While it was once considered “notably absent from southern South America, the western part of the Palearctic, and Australia ” (Löbl & Leschen 2003b), it is now understood that the low number of species in Brazil is a result of the lack of studies/collections involving Scaphidiinae (von Groll & Lopes-Andrade 2022). Throughout my field trips in Minas Gerais, Brazil, it was very common to collect specimens of Cyparium. Although this paper includes the description of only one new species, it should be noted that several others have been collected.
