Abstract
Eighteen species of long-legged flies (Dolichopodidae) are reported as new to Finland. A further species, Microphorellapraecox (Loew), is confirmed as a Finnish species. The status of Hydrophoruscallosoma Frey, 1915 is re-evaluated and a lectotype is designated for the species. Hydrophorusalbosignatus Ringdahl, 1919 is found to be a junior synonym of Hydrophoruscallosoma (syn. n.). Characters for identifying both sexes of Hydrophoruscallosoma and Hydrophorusaltivagus Aldrich are presented and illustrated with high-quality photographs.Entities:

Character table for distinguishing Frey from Aldrich. See Figs 1, 2, 3 for illustrations of the characters.
| character | ||
|---|---|---|
| face | wide, parallel-sided | narrower, broadened towards the clypeus |
| face, colour (males only) | silver, narrowly greenish under the antennae | green ground color obscured by silver only in the lower third-half |
| clypeus, shape | width of clypeus not much less than the height of face | width of clypeus clearly less than height of face |
| fore femur | one compact row of 6-13 ventral setae restricted to the basal third or half. Anteroventral setae missing or at lost 1-3 small, scattered ones | venrtal row with 3-8 sete in basal half. Anteroventral row of setae well developed, with 6-12 setae, reaching the apical third |
| wing color (females only) | wings almost transparent in both sexes | wing membrane faintly brownish esp. before vein M1+2 |
| spot above notopleural depression | white, round or oval in dorsal view | variable, usually small, dark to yellow, linear along notopleural suture. Never white and round |
| abdomen (females only) | lateral hairs of tergites 5 at let partially white in dorsal view. Usually also tergites 3-4 with partially pale lateral hairs | lateral hairs (in dorsal view) on tergites 3-5 black. Note that the ventral hairs on tergites are usually white. |
