Two new species of the long-legged fly genus Hurleyella Runyon & Robinson, 2010 are described and illustrated: Hurleyella belizensis sp. nov. from Belize and Hurleyella salina sp. nov. from alkali areas of the Northern Rockies of the USA (Idaho, Montana, Wyoming). The discovery of these new species greatly extends the known distribution of Hurleyella northward in the Nearctic and southward into the Neotropics. Notes, photos of habitats, a distribution map, and a key to the four known species of Hurleyella are provided.
