Revision of Nephochaetopteryx Townsend, 1934 (Diptera: Sarcophagidae).

Nephochaetopteryx Townsend, 1934 is a genus of flesh flies predominantly Neotropical in distribution, which comprises small species (4.0-7.3 mm) characterized mainly by vein R1 fully setulose dorsally and wing usually fumose between apical part of vein R2+3 and vein C.

Review of the Brazilian species of Udamopyga Hall, 1938 (Diptera: Sarcophagidae), with the description of a new species and a key to males and females.

Udamopyga Hall, 1938 sensu stricto previously comprised 20 species: three from the Nearctic Region and 17 from the Neotropics. A comparative morphological study of the seven species so far recorded from Brazil is presented, including a newly described species from the Brazilian Atlantic Forest, Udamopyga squamata sp. nov.

Retrocitomyia Lopes, 1982 (Diptera: Sarcophagidae): new species, new records, key to males, and an updated catalog.

Prior to this work, Retrocitomyia Lopes (Diptera: Sarcophagidae) included ten recognized species distributed exclusively in the New World. We here add a new species to the genus, Retrocitomyia sisbiota sp. nov.

FAMILY SARCOPHAGIDAE.

A catalogue of Sarcophagidae recorded from Colombia is presented, including 102 species in 26 genera, and two subfamilies. The geographical distribution by department is also given.

FAMILY CONOPIDAE.

A catalogue of the Conopidae known from Colombia, with 16 species distributed in four genera, is presented. The richest group is Stylogaster Macquart. Geographic distributions are given for each species.

An illustrated catalogue of the types of Stratiomyidae (Diptera: Brachycera) in the collection of Museu Nacional, Rio de Janeiro, Brazil.

A catalogue of the type specimens of Stratiomyidae (Diptera: Brachycera) held in the collection of Museu Nacional, Rio de Janeiro, Brazil (MNRJ) is presented. A total number of 50 type specimens of 18 valid Neotropical species were recognized and are listed in alphabetical order of subfamily, genus and specific epithet. Photos of 12 primary types of the species and bibliographical data of the original descriptions, labels and condition of all type specimens are also provided.

New Neotropical Culicoides and redescription of Culicoides reticulatus Lutz (Diptera: Ceratopogonidae).

Seven new species of the Culicoides reticulatus species group are described and illustrated based on specimens from Colombia, Panama and Brazilian states of northern (Amazonas, Pará and Roraima) and southeast region (Rio de Janeiro). The new species are compared with their similar congener, Culicoides reticulatus Lutz, and a systematic key, table with numerical characters to the females of the species are provided. Redescription of Culicoides reticulatus Lutz is given based on type series deposited in the Ceratopogonidae Collection of the Oswaldo Cruz Foundation, Brazil.

Synanthropy of sarcophagidae (Diptera) in La Pintada, Antioquia-Colombia.

Recently, populations of flies have increased in numbers given the elevated levels of organic matter waste produced by anthropic activities and domestication of animals. Such increase represents a worldwide health concern, since flies can be vectors of human diseases. The great variety of feeding and developmental habits of flies of the family Sarcophagidae taking place on animal corpses, feces and decomposed organic matter make them potential vectors of pathogens.

Temporal distribution of ten calyptrate dipteran species of medicolegal importance in Rio de Janeiro, Brazil.

Brazilian studies involving entomological succession patterns in carcasses have been used to describe the necrophagous entomofauna of a determined municipality or region with forensic objectives. Following the same objectives, an ecological study with 10 calyptrate dipterans was carried out during the winter of 2007 and the summer of 2008 in the metropolitan region of the municipality of Rio de Janeiro. The aim of this study was to describe several aspects of the phenology of these species in three neighbouring areas.

New records of calyptrate dipterans (Fanniidae, Muscidae and Sarcophagidae) associated with the decomposition of domestic pigs in Brazil.

The calyptrate dipterans are the most important decomposers of human cadavers. Knowledge of their species and distribution are of great importance to forensic entomology, especially because of the enormous diversity in Brazil. Carcasses of domestic pigs (Sus scrofa, L) were the experimental models used to attract calyptrates of forensic interest during the winters of 2006 and 2007 and the summers of 2006 and 2008.
