Abstract

The genus Liancalus Loew is revised for the Nearctic Region. Seven species are documented from this region including two new species: Liancalus genualis Loew, L. hydrophilus Aldrich, L. limbatus Van Duzee, L. pterodactyl sp. n., L. querulus Osten Sacken, L. similis Aldrich, and L. sonorus sp. n. Lectotypes are designated for the following species: L. genualis, L. hydrophilus, L. querulus, and L. similis. The species are illustrated, a key to males and females is provided, and their distributions mapped. Adults of Liancalus are some of the largest species of Dolichopodidae and commonly occur on waterfalls and vertical seeps.
