The four Palearctic species of the shore-fly genus Discomyza Meigen are revised, including the description of an undescribed species. The undescrihed species, D. baechlii, is found at higher elevations mainly in Austria and Switzerland (type locality: Graubünden: Ausserferrera-Cresta (1300-1670 m; 46°28'N, 9°31'E). Three species, D. baechlii, D. incurva, and D. maritima, form a monophyletic species group; the fourth species, D. maculipennis, has only been found in Japan in the Palearctic region and is undoubtedly an introduction from the Oriental region. Lectotypes are designated for: Discomyza amabilis Kertész, Discomyza pelagica Frauenfeld and Psilopa incurva Fallén. © Insect Systematics & Evolution (Group 6).
