Five Old World species of the dung beetle genus Onthophagus (nuchicorn
is, depressus, bonasus, gazella, and taurus) are presently recorded in
the United States, Canada, and Mexico. The current North American ran
ge of each, based on numerous literature records, specimens from priva
te collections, from the insect collections of Cornell University and
the Carnegie Museum of Natural History, and our own collecting, is map
ped. A brief diagnosis, habitus photographs, and illustrations of othe
r diagnostic features are provided to aid in accurate identification o
f these adventive species. We also report the presence of O. gazella i
n 2 new states in the U.S. (Kansas, Tennessee), and of O. taurus in 6
new states in the U.S. (Missouri, New York, Pennsylvania, Ohio, Tennes
see, West Virginia).
