摘要

Sarcophagidae (flesh flies; Diptera) include numerous species of socio-economic, medical, veterinary, and forensic importance, as their immature stages develop in the tissues of humans and other animals. Species identification is challenging, often requiring adult male specimens due to the reliance on genitalic characteristics, while morphological features of females remain largely uninformative. Sarcophagids are still underexplored, with even less attention given to their larval stages, which are dominant in carcasses. This study focuses on the morphological characterization of third-instar larvae of nine forensically relevant urban sarcophagid species: Blaesoxipha (Gigantotheca) plinthopyga (Wiedemann, 1830), Helicobia rapax (Walker, 1849), Oxysarcodexia fluminensis Lopes, 1946, Oxysarcodexia similata Lopes and Tibana, 1987, Peckia (Peckia) chrysostoma (Wiedemann, 1830), Peckia (Euboettcheria) collusor (Curran & Walley, 1934), Peckia (Squamatodes) ingens (Walker, 1849), Peckia (Pattonella) intermutans (Walker, 1861), and Sarcophaga (Liopygia) ruficornis (Fabricius, 1794). We provide a dichotomous key for third-instar larvae, using observable morphological characters under stereoscopy/microscopy and slide preparations. This study advances regional forensic entomology by enabling rapid and reliable identification from field-collected larvae.
