A review of the Neotropical species of the shore-fly genera Orasiopa and Pectinifer (Diptera: Ephydridae)

Species of two genera of the tribe Discocerinini from the Neotropics are reviewed with an emphasis on the fauna from Brazil. The two species, Orasiopa (Reymontopa ) mera (Cresson, 1939) and Pectinifer aeneus (Cresson, 1918), are described, illustrated and new occurrence data are provided. Phylogenetic relationships of these two genera into the tribe are discussed. To facilitate identification of these species, we have included diagnoses of the Discocerinini and both genera and have also provided an annotated key to the New World genera in this tribe. We have also provided illustrations, photographs, and scanning electron micrographs of external structures and of structures of the male terminalia for included species.

Two new Neotropical species of Drosophilinae (Diptera: Drosophilidae) from Uruguay

Two new species of Drosophilidae from Uruguay are described and illustrated: Drosophila montevidensis sp. nov. (Holotype male in MZSP: Facultad de Agronomía, Universidad de la República, Montevideo city, Department of Montevideo), and Scaptomyza pipinna sp. nov. (Holotype male in MZSP: Sarandí del Consejo, near north shore of Laguna de Castillos, Department of Rocha). The former species belongs to the D. tripunctata group and is sibling to Drosophila nappae Vilela, Valente & Basso-da-Silva, 2004, differing mainly in characters of the aedeagus. The latter is closely related to Scaptomyza striaticeps Wheeler & Takada, 1966, from which it can be distinguished by color and terminalia characters. The new Drosophila species was successfully cultured in a modified banana-agar medium which is provided. Photomicrographs of mitotic and meiotic chromosomes of D. montevidensis sp. nov. are also included.

A review of Scatellini (Diptera: Ephydridae) from Brazil

Scatellini was proposed by Wirth & Stone, 1956 and currently includes 242 described species in nine genera­. The tribe has representatives in all biogeographic regions and about 70 species occur in the Neotropical Region. Prior to this study, only two species were recorded from Brazil: Scatella obscura and Limnellia itatiaia. In this paper, species of Scatellini from Brazil are reviewed with an emphasis on the fauna from southern Brazil, where six new species have been discovered and are described herein: Scatella praia, S. plaumanni, S. rara, Scatophila darrowae, S. dianneae, and S. prainha. To facilitate identification of the tribe and included genera and species, we have included diagnoses of these taxa and have also provided an annotated key to the Neotropical genera in Scatellini. We have also provided illustrations of structures of the male terminalia of all included species of the genus Scatophila.

A review of Parydra (Diptera: Ephydridae) from Brazil

Species of the shore-fly Parydra Stenhammar, 1844 from Brazil are reviewed with an emphasis on the fauna from southern Brazil, where one new species, Parydra arcuata sp. nov. - state of Paraná, municipality of Castro (8 km N, 24º45.3'S, 49º58.9'W) -, has been discovered and is herein described. To facilitate identification of species, we have included a diagnosis of the genus. We have also provided illustrations of structures of the male terminalia for all included species.
