Revision of the genus Lopesiodinia Prado, 1973 (Diptera: Odiniidae) with description of three new species, and a key to the extant Neotropical genera and species of Traginopinae.

The Neotropical genus Lopesiodinia Prado is represented by two species, L. diversa Prado (Brazil: Rio de Janeiro) and L. alvarengai Prado (Brazil: Par). The genus is reviewed here, and three new species are described and illustrated: Lopesiodinia marcusi sp. nov. (Brazil: Amazonas, Maranho), L. argentata sp. nov. (Brazil: Amazonas) and L. pontarolloi sp. nov. (Brazil: Amazonas, Maranho). A key to identify the subfamilies and extant genera and the species of Traginopinae from the Neotropical Region is presented.
