RESUMO
Piophilidae are a small family of Diptera with a worldwide distribution and which are historically associated with human activities. In addition to their economic importance, piophilid larvae can also be of medical and legal relevance. Within a medicolegal context, piophilids are frequently associated with cadavers in advanced stages of decomposition, thus being potentially useful forensic indicators and they have been reported also from archaeo-funerary contexts. An accurate species identification is therefore an essential prerequisite to ensure the reliable analysis of insect material in medical, forensic and archaeological investigations. Identification of the adult piophilid flies is possible because of the availability of identification keys, in contrast immature insects, especially puparia, have been poorly investigated and described. In this paper, puparia of 11 species of forensic interest (Piophila casei, Piophila megastigmata, Parapiophila atrifrons, Parapiophila flavipes, Parapiophila vulgaris, Protopiophila litigata, Liopiophila varipes, Prochyliza nigrimana, Prochyliza xanthosoma and Stearibia nigriceps in subtribe Piophilina and Centrophlebomyia furcata in subtribe Thyreophorina) are described and a molecular analysis, based on the COI sequencing, is presented to show the potential of the molecular approach in their identification.
