Abstract The Nearctic Idiocerini exclusive of the fauna of the Sonoran subregion are reviewed. The 68 recognized species are assigned to three genera: Idiocerus Lewis, Rhytidodus Fieber, and Balcanocerus Maldonado-Capriles. Three subgenera of Idiocerus are recognized, including I . ( Liocratus ) Dub. and I . ( Populicerus ) Dlab. (n. stat). Sahlbergotettix Zvk., 1953, Viridicerus Dlab., 1974, Tremulicerus Dlab., 1974, and Acericerus Dlab., 1974 are synonymized with Idiocerus Lewis, 1834. Sixteen new species of Idiocerus are described: aureus , carolina , cedrus , freytagi , gillettei , immaculatus , inebrius , iodes , lucidae , midas , pericallis , taiga , unicolor , vanduzeei , venosus , and xanthiops . I . varions n. n. is created for varias DeLong & Hershberger, 1947 ( nec Germar, 1818). I . lunaris Ball (n. stat.), I . obsoletus (Wlk.) (n. stat.), and I . raphus Freytag (n. stat.) are recognized as valid species for the first time. Twelve other species are removed from synonymy. I . verrucosus Ball is placed as a subspecies of I . musteus Ball (n. stat.). Five new synonymies are created: alnirubratus Bliven, 1955 = I . couleanus Ball & Pkr., 1946; nigrens DeL. & Cld., 1937 = I . distinctus Gill & Bak., 1895; duzeei Prov., 1890 and vagus Ball, 1902 = obsoletus Walker, 1851; and apertus DeL & Hbr., 1947 = I . verticis (Say), 1831. Additional characters of the male antennae, male abdominal apodemes, and female ovipositor are described and illustrated. The phylogeny and hosts of the members of Idiocerus are discussed. Keys are provided to the genera of the Nearctic Idiocerini, and to the species of Idiocerus of the Nearctic region, exclusive of the Sonoran subregion, for both sexes.
