Lopesiodinia alvarengai Prado, 1973 (Odiniidae: Traginopinae) with the first description of the male and the neotype designation.

The type specimen of Lopesiodinia alvarengai Prado is lost. It is being redescribed and illustrated based on specimens from the type locality (Jacareacanga, Par, Brazil) and the neotype is here designated with the purpose of clarifying the taxonomic status and objectively securing stability of nomenclature.

A new species of Neorhinotora Lopes, 1934 (Diptera: Heleomyzidae) and new records of the genus from Northeastern Brazil.

The Neotropical genus Neorhinotora Lopes is currently represented by five species: N. amapaensis Guimares & Papavero, N. aristalis (Fischer), N. diversa (Giglio-Tos), N. elsalvadorensis Menezes, Calhau & Ale-Rocha, and N. mutica (Schiner). A new species is described and illustrated: Neorhinotora fapema, sp. nov. from Maranho, Brazil, bringing the number of valid species to six. A revised key is provided for species identification.

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.
