The Empis subgenus Enoplempis Bigot, east of the Rocky Mountains of North America is revised. A total of 19 species are recorded from this region including seven new species: E. (En.) amytis Walker, E. (En.) appalachicola Sinclair sp. nov., E. (En.) arthritica Melander, E. (En.) ctenonema Melander, E. (En.) enodis Melander, E. (En.) gladiator Melander, E.(More)
The Tachytrechus alatus species group is revised. The species group is defined within the genus Tachytrechus on the basis of possession of a strong basiventral bristle on the fore femur and very reduced pulvilli on the midand hindlegs of both sexes. Males also possess a strongly reduced vertical bristle, and a cluster of 2–3 strong bristles on both the fore(More)
The western North American empidid genus Philetus Melander is reviewed, including redescription of the two included species, P. memorandus Melander and P. schizophorus Melander. A lectotype is designated for P. schizophorus. The        distributions of both species are mapped and the male terminalia are illustrated. The female of P. schizophorus is(More)
