03A287D1C301FFA0FF1B0F40A59DCD7B.taxon	description	The genus Oxyvinia was described by Dodge (1966) based on two species: Oxyvinia piliventris and Oxyvinia grata. Dodge (1966) designated O. piliventris as type species based on two males from Venezuela, while O. grata was initially described by Lopes (1953) in Dexosarcophaga, although with some reservations regarding its generic assignment. Dodge (1996) included as generic characters the male sternite 5 cleft nearly to the base, cercus with an external subapical tooth and phallus separated into 2 segments. Lopes (1969) enumerated five species within Oxyvinia, and with the exception of O. piliventris, the remaining four species had not been originally included under the genus Oxyvinia. Pape (1996) listed 11 species of Oxyvinia and presented the following generic diagnosis (besides larval characters): row of frontal bristles almost parallel, parafacial setae very small and hairlike, anterior postgenal setae black, postalar wall setose, male mid femur with ctenidium of normal spines, male sternite 5 deeply cleft with almost parallel sides, terminalia red, juxta reduced or not developed. Mello-Patiu & Riccardi (2021) revisited and illustrated the holotype of Orosarcophaga ornata, concluding that Orosarcophaga and Oxyvinia were synonyms. They provided an updated generic diagnosis as well as a list with the 11 recognized Orosarcophaga species. Although Mello-Patiu & Riccardi (2021) did not include coloration in their generic diagnosis, we observed a common pattern in Orosarcophaga species: the intense golden microtomentum on the head and thorax, particularly in the humeral region. Orosarcophaga ’ s distribution is restricted to the Neotropical Region (Fig. 1). The distributional patterns of Orosarcophaga remain unclear, and only Orosarcophaga excisa seems to be associated with savanna environments in the Amazon region (Carvalho-Filho et al. 2022) and other biomes. Although species of Orosarcophaga exhibit a wide distributional range, the under-sampling of these species presents challenges in recognizing their distributional patterns.	en	Gomes, Marina Morim, Mello-Patiu, Cátia Antunes De, Couri, Márcia Souto (2025): The Neotropical genus Orosarcophaga Townsend: illustrated key and redecription of Orosarcophaga grisea Lopes (Diptera: Sarcophagidae).

03A287D1C304FFA4FF1B0A67A7A6CFBB.taxon	discussion	Remarks. O. grisea was originally described by Lopes (1982), and, so far, our knowledge of this species had been limited to the illustrations of the holotype produced by the same author (Lopes 1982: figs 33 - 36). Comparing the holotype to the newly identified specimens, we observed slight differences, particularly in the pregonite, sternite 5 and vesica (Fig. 2 A – F). We attribute these differences to different clearing methods of the terminalia (e. g., KOH or lactic acid), as well as to the different position of the structures during the photography. Additionally, the original description did not include descriptions of the lateral and median styles. We have identified that the sclerotized plate previously interpreted as the “ lateral plate ” by Lopes (1982) corresponds to a sclerotized region within the vesica (Fig. 2 F, arrow). The holotype of O. grisea was collected in Peru, and we herein expand its distribution to the Brazilian Amazon Forest and Atlantic Rainforest biomes, both of which are Neotropical rainforests. This indicates that, up to this point, this species has only been recorded in rainforests.	en	Gomes, Marina Morim, Mello-Patiu, Cátia Antunes De, Couri, Márcia Souto (2025): The Neotropical genus Orosarcophaga Townsend: illustrated key and redecription of Orosarcophaga grisea Lopes (Diptera: Sarcophagidae).
