Beschreibung:
<p>A new key to males of Group B (Van Duzee, Cole, and Aldrich, 1921) of the North American species of Dolichopus is presented. Detailed examination of the cercus, flange, and posterior clasping appendages of the postabdominal capsule of species related to D. gratus Loew yielded excellent discriminatory characters (figured). This led to the removal of D. mercieri Parent from synonymy and the recognition of D. gaigei, n. sp. (Washington, New Brunswick) and D. gratiolus, n. sp. (New Hampshire to South Carolina). Type-species are designated for taxa proposed by Frey in 1915 as subgenera: Eudolichopus (Musca plumipes Scopoli); Leucodolichopus (Dolichopus remipes Wahlberg); Melanodolichopus (Dolichopus stenhammari Zetterstedt). A truly subgeneric division of Dolichopus is, however, considered premature.</p>
