RESUMO

The Nearctic species of Saropogon Loew, 1847 north of Mexico are reviewed, with 19 species recognized and one described as new: Saropogonpyrodes sp. nov. from Arizona. This previously recognized new species has awaited description since its first collection in 1964. Only after a community scientist posted photographs taken in nature to an online database did its description become a priority. All species of Saropogon occurring in the Nearctic Region north of the Mexican border have been reexamined. Photographs and diagnoses of all species are provided with a distribution map of the included specimens studied. An updated key to the Nearctic species north of Mexico is provided. Finally, the need for a review of the diverse Mexican fauna is expressed.

RESUMO

Two new species of Martintella Artigas, 1996, Martintella aurata sp. nov. and Martintella fernandoi sp. nov., from Costa Rica are described and illustrations of species of the genus are provided.

RESUMO

Two recent faunistic surveys in the Brazilian Atlantic Forests region, the PROFAUPAR and the Biota/FAPESP Program, have provided important material for the discovery of new taxa from Brazil. We describe herein four new species of robber-flies of the genus Oidardis (O. falcimystax sp. n., O. fontenellei sp. n., O. maculiseta sp. n. and O. marinonii sp. n.), including illustrations and details on male hypopygia and female genitalia. A distribution map and a key to the species of Oidardis from the Brazilian Atlantic Forests region, including O. triangularis (Hermann), 1912, are also provided.
