Complete mitochondrial genomes from three species of the genus Peckia (Sarcophagidae) with forensic entomology interest

Abstract

Peckia is one of the most important genera in the Sarcophagidae family of flesh flies. This genus is distributed in Brazil and Latin America, and its species can be used to estimate the Post Mortem Interval (PMI) in forensic investigations. In this communication, we present four mitochondrial genomes (mtDNA) from three Peckia species: P. australis, P. collusor, and P. resona. These mtDNA range from 15,116 bp to 15,234 bp in length and have 22 tRNA genes, 13 protein-coding genes (PCG), and two rRNAs distributed along both the strands. These data expand the knowledge about the Sarcophagidae genomes and present, for the first time, four complete mtDNA sequences of the Peckia genus. We show novel complete mtDNA sequences of flesh fly species of forensic importance. Our data expand the knowledge on the molecular database for the identification of these species, and is an important step towards increasing the databases and can help on the identification of new species, particularly in the forensic context.
