Abstract

The genus Dyschirius includes 56 North American species which are arranged in 13 species groups. Keys are provided for the species groups and the species. Four new species are described: D. sculptus Bousquet (type locality: Pass-a-Grille Beach, Florida); D. ferrugineus Bousquet (type locality: Goose Island State Park, Texas); D. larochellei Bousquet (type locality: 6 mi. S Lake Placid, Florida); and D. comatus Bousquet (type locality: Highlands Hammock, Florida). Six species names are placed in synonymy for the first time. They are (with the junior synonym listed first): D. arizonicus Van Dyke 1943 = D. interior Fall 1922; D. duplicates Fall 1901 = D. affinis Fall 1901; D. desertus Fall 1925 = D. perversus Fall 1922; D. subpunctatus Hatch 1949 = D. sphaericollis (Say 1825); D. basalis LeConte 1857 and D. transmarinus Mannerheim 1853 = D. integer LeConte 1851. The adult and larval character states of the genus are listed and comments are provided for each species group.
