The American species of the genera Bryoporus Kraatz and Bryophacis Reitter are revised for America north of Mexico. Two new related genera are described: Bolitopunctus (type species Bryoporus muricatulus Hatch) and Neobolitobius (type species Lordithon varians Hatch).The following new species are described: Bryoporus niger, Bolitopunctus punctatissimus, Bryophacis arcticus, Bryophacis canadensis, and Bryophacis smetanai. Six new combinations are created: Bolitopunctus muricatulus (Hatch) [from Bryoporus], Neobolitobius varians (Hatch) [from Lordithon], Bryophacis discalis (Hatch) [from Mycetoporus], Bry. punctatissimus (Hatch) [from Mycetoporus], Bry. punctulatus (Hatch) [from Mycetoporus], and Bry. rubescens (Hatch) [from Lordithon].Use of the generic names Bryoporus Kraatz and Bryophacis Reitter is discussed. Lectotypes are designated for Bryoporus rufescens LeConte and its junior synonyms B. rubidus LeConte and B. flavipes LeConte, and Bryoporus testaceus LeConte and its junior synonym B. parvulus Casey.All species of Bryoporus, Bryophacis, Bolitopunctus, and Neobolitobius are described and illustrated with line drawings and scanning electron photomicrographs. Keys are provided to distinguish all genera of North American Bolitobiini and all species of the genera treated in this revision. The New World distribution of each species treated is mapped. The biology of each species, if known, is discussed.
