Extract

The genus Roederioides was erected by Coquillett in 1901 for the single species juncta Coquillett, described from Saranac Inn, New York. The species has since been recorded only from Mt. Washington, New Hampshire. A second species has been described from the Madeiras by Frey. This paper describes five new species from North America and presents a revised description of the genus.

The type of the genus, juncta, was collected in association with black flies, and recent collections have been made from black fly swarms. It is possible that juncta, and possibly other species of the genus, are predators of black flies, both as adults and as larvae.
