RESUMO

Abstract Although a corpse can harbor several species of flies, only a few have been sufficiently studied to be used as forensic indicators. Sarcophagidae are an example of how the forensic use of insects can be impaired by taxonomic and biological data limitation. This manuscript provides the first record of the Neotropical flesh fly Microcerella halli (Engel, 1931) on a human body and its use in forensics. M. halli and Sarconesia chlorogaster (Widemann, 1830) were sampled from a body located indoors at 20 °C. Only M. halli was used to estimate the mPMI (minimum post mortem interval) because it was the oldest larval stage on the corpse. Based on the development time of M. halli we estimate an mPMI of at least 10 days. In addition, we provide for the first time a case in which a flesh fly was the main source of entomological evidence in Southern Brazil. We also provide evidence that Sarcophagidae arrived before Calliphoridae in this case, an unusual successional pattern.

RESUMO

ABSTRACTThe identification of female flesh flies was always considered a difficult task since morphological descriptions and keys for females are rare. Even in a forensic entomology framework, where females play a major role, female flesh flies are usually not identified. In order to fill this gap in Southern Brazil fauna we provide detailed descriptions and key for the female of nine species included in four genera: Microcerella halli (Engel), Oxysarcodexia paulistanensis (Mattos), Oxysarcodexia riograndensis (Lopes), Peckia (Euboettcheria) australis (Townsend), Peckia(Euboettcheria) florencioi (Prado and Fonseca), Peckia (Pattonella) intermutans (Walker), Peckia(Pattonella) resona (Lopes), Peckia (Sarcodexia) lambens (Wiedemann), and Sarcophaga(Bercaea) africa (Wiedemann). These species are distinguished mainly by genital characters as tergite 6 divided or undivided, presence of tergite 8, spermatheca morphology and vaginal plate shape.

RESUMO

Pictorial identification key for species of Sarcophagidae (Diptera) of potential forensic importance in southern Brazil. Species of the subfamily Sarcophaginae are important to forensic entomology due to their necrophagous habits. This contribution presents a pictorial key for the identification of 22 Sarcophaginae species in 10 genera that are commonly found in southern Brazil. Photographs of the main structures used in species identification, mainly from the male terminalia, are provided.


Chave pictórica para a identificação das espécies de Sarcophagidae (Diptera) de potencial importância forense do sul do Brasil. Espécies da subfamília Sarcophaginae são importantes para a entomologia forense devido ao seu hábito necrófago. Este trabalho apresenta uma chave pictórica para a identificação de 22 espécies de Sarcophaginae de 10 gêneros encontradas na região sul do Brasil. São fornecidas fotografias dos principais estruturas das espécies, principalmente da terminália masculina.
