Abstract

Laeviprosopon Glaessner, 1933, is a member of the Prosopidae von Meyer, 1860 within the Homolodromioidae. Members of the genus lack lineae homolicae, typical of the Homoloidea. Herein we expand the range of the genus to the Tithonian Ernstbrunn Limestone, from which it was previously unknown, and recognize two new species from that unit, Laeviprosopon grandicentrum and L. laculatum. Laeviprosopon thus far is known only from the Late Jurassic to Early Cretaceous of Europe, based upon seven species. Referral of Laeviprosopon to the Prosopidae does not expand the range of the family nor does it substantially change the diagnosis for it.
