Abstract

The Nearctic species of Dicraeus Loew (Diptera: Chloropidae) are revised. Eight species are recognised in North America: Dicraeus curtisinew species is described from the western United States of America; the Palaearctic species D. vagans (Meigen) is newly recorded in North America; D. elongatus Sabrosky; D. fennicus Duda; D. incongruus Aldrich; D. ingratus (Loew); D. tibialis (Macquart); and D. wilburi Sabrosky are redescribed. All species are described and illustrated and a key to species is provided. Dicraeus aberrans Sabrosky, described from New Mexico, United States of America, is transferred to the genus Notaulacella Enderlein as Notaulacella aberransnew combination. This represents the first Nearctic record of the previously Neotropical genus Notaulacella.
