DNA Barcoding Identifies Unknown Females and Larvae of R.-D. (Diptera: Fanniidae) from Carrion Succession Experiment and Case Report.

Application of available keys to European Fanniidae did not facilitate unequivocal species identification for third instar larvae and females of Robineau-Desvoidy, 1830 collected during a study of arthropod succession on pig carrion. To link these samples to known species, we took the advantage of molecular identification methods and compared newly obtained cytochrome oxidase subunit I (COI) barcode sequences against sequences deposited in reference databases. As an outcome of the results obtained, we describe for the first time a third instar larva of Malloch, 1910 and (Rondani, 1866) and a female of d'Assis-Fonseca, 1966. We provide combinations of characters allowing for discrimination of described insects from other Fanniidae. We provide an update for the key by Rozkošný et al. 1997, which allows differentiation between females of and other species of Fanniidae. Additionally, we provide a case of a human cadaver discovered in Southern Poland and insect fauna associated with it as the first report of larvae developing on a human body.
