The Passalidae (Coleoptera, Scarabaeoidea) from Bolivia, with the descriptions of three new species

Abstract. Employing data from literature, examination of specimens in collections, and a field trip, a list of the species of Passalidae from Bolivia is elaborated. A total of 38 species is reported, including new records of Passalus inca Zang, 1905 and P. lunaris (Kaup, 1871), and three new brachypterous species: Passalus bolivianussp. nov., P. canoisp. nov., and P. gonzalezaesp. nov. Most of the species (27) belongs to the Passalini tribe, especially to the genus Passalus Fabricius, 1792 (19 species); the Proculini tribe is represented by eleven species in three genera. The number of species of Bolivia is low and reflects the lack of a systematic exploration of this country; more surveys are needed, especially in ecosystems such as montane forest and tropical rain forest.
