Summary: | Sarcophagidae is a family of true flies frequently found colonizing carcasses and corpses as adults and/or larvae, therefore, they are of great forensic value in the medico-legal field. Thus, this study aims to inventory the sarcophagids species and describe their succession process in the decomposition of swine carcasses in the Cerrado (savanna-like vegetation), Brazilian Northeastern region. A total of 10,819 specimens were collected, belonging to 45 sarcophagid species. Of this total, one species was recently described (Helicobia neuzalmeidae Silva, Brasil, De-Souza & Carvalho-Filho), two [Blaesoxipha (Acanthodotheca) denieri (Blanchard) and Dexosarcophaga pusilla Lopes] are new records for the Cerrado biome, five [Argoravinia (Argoravinia) catiae Carvalho Filho & Esposito, B. (A.) denieri, Nephochaetopteryx orbitalis (Curran & Walley), Peckia (Sarcodexia) tridentata (Hall) and Tricharaea (Sarcophagula) ramirezi (Lopes)] are new records for the Northeast region and eight are new records for the state of Maranhão. The species A. (A.) catiae, Blaesoxipha (Gigantotheca) stallengi (Lahille), D. pusilla, H. neuzalmeidae, Lipoptilocnema misella Lopes, Oxysarcodexia bakeri (Aldrich) and Retrocitomyia retrocita (Hall) were collected for the first time in pig carcasses. Peckia (Sarcodexia) lambens (Wiedemann) and Oxysarcodexia thornax (Walker) were the most abundant species. In both collection seasons, five species were carcasses pioneers at an early stage. The majority of species (42 spp.) were collected during the dry season, primarily during the black putrefaction (39 spp.) and butyric fermentation (30 spp.) stages. The greatest number specimens (n = 6,484) were recorded during the rainy season, at the butyric fermentation (n = 2,517) and black putrefaction (n = 2,080). |
