Abstract

While working on the pseudoscorpion collections of the Illinois State Natural History Survey and the American Museum of Natural History, the writer found two new species of the genus Hysterochelifer Chamberlin, 1931, as emended by Beier (1932). The present paper gives the descriptions of these two new species and in addition gives new records for Dactylochelifer copiosa Hoff. The descriptions are based on specimens cleared in beechwood creosote and mounted in Canada balsam. Previous to clearing, the body but not the appendages of each individual was treated with potassium hydroxide solution. All drawings were made with the aid of a camera lucida. Types are deposited with the Illinois State Natural History Survey at Urbana, Illinois.
