Taxonomic revision of the Peruvian genus Pilobaloderes Kulzer, 1958 (Coleoptera, Tenebrionidae, Pimeliinae, Praociini).

The monotypic genus Pilobaloderes Kulzer (Pimeliinae: Praociini), endemic to Peruvian Andes, is revised. Based on examination of recently collected specimens, we describe the female of the type species and a new species, Pilobaloderes aquilonarius sp. nov., emphasizing dimorphic and diagnostic characters of the protibiae. A redescription of the genus and its species, with remarks about sexual dimorphism are included. Habitus photographs, illustrations of protibiae, genital features, and a distribution map are also presented.
