Abstract
The eucoiline genus Preseucoela Buffington is described. Also provided is a redescription of Preseucoela pallidipes (Ashmead), new combination, and the descriptions of Preseucoela heratyi Buffington, new species, and Preseucoela imallshookupis Buffington new species. One definitive rearing record was found, and indicates hosts for species of Preseucoela are agromyzid flies. Agrostocynips Diaz, another eucoiline genus parasitic on agromyzids, is discussed. Agrostocynips robusta (Ashmead), new combination, and Agrostocynips diastrophi (Ashmead), new combina- tion, are proposed, raising the number of recognized species of Agrostocynips to four, and expanding the range of Agrostocynips into central North America.References
