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 bolivianus sp. nov., P. canoi sp. nov., and P. gonzalezae sp. 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.
