Abstract
A new parasitoid wasp species, the eucoiline Hexacola lemnaphilae Gaddi & Díaz, is described. Specimens were reared from pupae of Lemnaphila neotropica Lizarralde de Grosso (Diptera: Ephydridae), a shore fly that mines least duckweed, Lemna minuta Kunth (Lemnaceae); the material examined was collected in Berisso (Buenos Aires, Argentina) and is housed in the collection of the División Entomología of the Museo de La Plata, Argentina. Photographs of diagnostic characters and data about the ecological and economic importance of these organisms are included.References
