Description of three new species of Dexosarcophaga (Diptera, Sarcophagidae) from Brazil with new information on synonyms and filling gaps in species distribution.

Three new species of DexosarcophagaTownsend, 1917 are described based on male specimens collected in Brazil, Dexosarcophaga sinoisp. nov., Dexosarcophaga autisferasp.

Vertical stratification of insect abundance and species richness in an Amazonian tropical forest.

Tropical forests are among the most biodiverse biomes on the planet. Nevertheless, quantifying the abundance and species richness within megadiverse groups is a significant challenge. We designed a study to address this challenge by documenting the variability of the insect fauna across a vertical canopy gradient in a Central Amazonian tropical forest.

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.

Flesh Flies (Diptera: Sarcophagidae) Attracted to a Snake Carcass (Boa constrictor) in Yucatan Peninsula, Mexico.

A study was carried out to determine Sarcophagidae diversity attracted to the different stages of decomposition of a Boa constrictor cadaver during late winter in the Yucatan Peninsula. As a result of this study, seven species of Sarcophagidae were documented, Oxysarcodexia conclausa (Walker, 1861) (Diptera: Sarcophagidae), Peckia (Euboettcheria) volucris (Wulp, 1895) (Diptera: Sarcophagidae), Blaesoxipha (Gigantotheca) plinthopyga (Wiedemann, 1830) (Diptera: Sarcophagidae), Oxysarcodexia amorosa (Schiner, 1868) (Diptera: Sarcophagidae), Ravinia derelicta (Walker, 1853) (Diptera: Sarcophagidae), Ravinia effrenata (Walker, 1861) (Diptera: Sarcophagidae), and Titanogrypa (Cucullomyia) placida (Aldrich, 1925) (Diptera: Sarcophagidae), The last five species listed are the first documentation of their presence in the Yucatan Peninsula in Mexico. Sarcophagids were present throughout the decomposition process; however, the greatest abundance and diversity of this family were present during the advanced decay stage.
