Abstract

Two species of Hybosoridae, Hybosorus illigeri Reiche and Pachyplectrus laevis LeConte, are distributed in the United States. For the introduced species H. illigeri, three new country records are reported (Dominican Republic, Nicaragua, and Venezuela); six new state records are recorded in the United States (Arkansas, Arizona, Kansas, Missouri, New Mexico, and Virginia); and 10 new state records are reported in Mexico (Baja California Sur, Chiapas, Michoacán, Nuevo León, Sinaloa, Sonora, Tamaulipas, Veracruz, Querétaro, and Yucatán). Information on the predatory habits of H. illigeri and a report as a turfgrass pest in the state of Arizona are provided. Pachyplectrus laevis is redescribed, and information on its biology and distribution is provided. A key to the species is provided along with diagnostic illustrations.
