Abstract: The Nearctic species of the genus Tachyempis Melander, 1928 (Diptera: Hybotidae, Tachydromiinae) are revised. The following four species are recognised: T. agens (Melander) (type species of the genus), T. calva (Melander), T. cinerea Melander and T. universalis (Melander). The following two new synonyms are proposed: T. longipennis Melander, 1958 = T. cinerea Melander, 1928; T. nervosa Melander, 1928 = T. universalis (Melander, 1910). Redescriptions, illustrations of male terminalia, known distributions and a key to species are included. In addition, Tachyempis is re-defined and a revised key to the Nearctic genera of the tribe Tachydromiini is provided.
