Abstract

New insights into the genus Stenotothorax Schmidt (Coleoptera: Scarabaeidae: Aphodiinae: Aphodiini) allowed for an influx of new materials from many new localities, and the realization that the genus needs revision. In this work, newly discovered characters used to distinguish species are defined. Stenotothorax lanei (Saylor) is redescribed. Diagnosis and new distributional data are presented for S. lanei, S. mcpeaki Gordon and Skelley, S. washtucna (Robinson) and S. woodleyi Gordon. Seven new species are described from the northwestern United States: S. lahontanensis, S. niviviator, S. odontomonteus, S. schneppi, S. smilodon, S. winnemucca, and S. wintoni. All new species are illustrated and compared with presumed closest relatives.
