The complete mitochondrial genome of Fannia canicularis (Diptera: Fanniidae)

Fannia canicularis (Linnaeus, 1761) is a species from the family Fanniidae. In this study, we sequenced and analyzed the complete mitochondrial genome of F. canicularis for the first time. The circular mitogenome is 15,826 bp in length, and includes 13 protein-coding genes (PCGs), 22 transfer RNA genes, two ribosomal RNA genes, and a non-coding control region. The family Fanniidae formed a monophyletic clade in the phylogenetic tree based on 13 concatenated PCGs, sister to three other families in Diptera.

(Diptera: Fanniidae) from Carrion Succession Experiment and Case Report

Simple Summary

Insects are frequently attracted to animal and human cadavers, usually in large numbers. The practice of forensic entomology can utilize information regarding the identity and characteristics of insect assemblages on dead organisms to determine the time elapsed since death occurred. However, for insects to be used for forensic applications it is essential that species are identified correctly. Imprecise identification not only affects the forensic utility of insects but also results in an incomplete image of necrophagous entomofauna in general. The present state of knowledge on morphological diversity and taxonomy of necrophagous insects is still incomplete and identification of immature and female forms can be extremely difficult. In this study, we utilized molecular identification methods to link conspecific sexes and developmental stages of forensically important flies. We identified larvae and females of flies collected from animal and human cadavers which otherwise were morphologically unidentifiable. The present study fills a gap in taxonomy of flies and provides data facilitating application of new species as forensic indicators.

Abstract

Application of available keys to European Fanniidae did not facilitate unequivocal species identification for third instar larvae and females of Fannia 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 Fannia nigra Malloch, 1910 and Fannia pallitibia (Rondani, 1866) and a female of Fannia collini 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 F. collini 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 F. nigra larvae developing on a human body.

Insights on Funeral Practices and Insects Associated With the Tombs of King Ferrante II d'Aragona and Other Renaissance Nobles

The impressive Sacristy of the Basilica of San Domenico Maggiore contains 38 wooden sarcophagi with the bodies of 10 Aragonese princes and other Neapolitan nobles, who died in the 15th and 16th centuries. To improve the knowledge about the entomofauna associated with bodies in archaeological contexts, herein we provide insights on the funerary practices and the insect community associated to Ferrante II King of Naples and other Italian Renaissance mummies of the Aragonese dynasty buried in the Basilica of St. Domenico Maggiore. We identified 842 insect specimens: 88% were Diptera (Muscidae, Fanniidae, and Phoridae), followed by 9% Lepidoptera (Tineidae) and 3% Coleoptera (Dermestidae and Ptinidae). Ninety-seven percent of the specimens were collected from the coffin of Francesco Ferdinando d'Avalos, which was the best preserved. A lack of fly species characterizing the first colonization waves of exposed bodies was noted. The most common fly was the later colonizing muscid Hydrotaea capensis (Wiedemann); only a few Fanniidae (Fannia spp.) were retrieved. The lack of blowflies, coupled with recording H. capensis as the dominant fly, supports our hypothesis that corpses have been kept indoors for a long time under confined environmental conditions. Other explanations include odorous oils/balms having been used in the embalming process, causing the delay or stopping the arrival of first colonizer flies. Hermetically sealing of the coffin with bitumen may also have played a role in preventing access to the corpses. This scenario describes a historical context characterized by a well-advanced knowledge of body preparation, with specific burial techniques adopted for nobles.

Descriptions of three new carbonaria-group species of Fannia Robineau-Desvoidy from China, with a key to the carbonaria-group species (Diptera, Fanniidae)

A historical review of the Fanniacarbonaria-group is provided and three new species are described from China: Fanniafani Wang & Wu, sp. n., Fannianitidiventris Wang & Zhang, sp. n. and Fanniasubmaculata Wang & Zhao, sp. n.. One species, Fannianorvegica Ringdahl, 1934, is recorded for the first time from China. Illustrations of male terminalia of these four species and a taxonomic key to the males of known species in the group are given. The Fanniacarbonaria-group now includes 30 species distributed in the Holarctic Region and northern part of the Oriental Region.

Fanniidae (Diptera): new synonym, new records and an updated key to males of European species of Fannia

Based on revision of large recent collections of the authors, the following five species are first recorded from the Czech Republic: Fannia collini d'Assis-Fonseca, 1966 (simultaneously first record in Central Europe), Fannia lugubrina (Zetterstedt, 1838), Fannia melania (Dufour, 1839), Fannia slovaca Gregor & Rozkošný, 2005, and Fannia brinae Albuquerque, 1951 (simultaneously first record from low altitudes). Another species, Fannia alpina Pont, 1970, is first recorded from Slovak Republic, and Fannia cothurnata (Loew, 1873) is first recorded from Kazakhstan. An updated key to males of European species of Fannia is presented. A list of Czech and Slovak Fanniidae is appended. One new synonym is established: Fannia lucida Chillcott, 1961 is considered junior synonym of Fannia norvegica Ringdahl, 1934. Altogether two species are first recorded from Bohemia [Fannia cothurnata (Loew, 1873) and Fannia vespertilionis Ringdahl, 1934] and three for Moravia [Fannia alpina Pont, 1970, Fannia conspecta Rudzinski, 2003, and Fannia limbata (Tiensuu, 1938) - this species considered in Central Europe very rare was found in numbers near waters both running and standing in early spring under unusually warm temperature conditions].

Taxonomic review of the postica-group of Fannia Robineau-Desvoidy (Diptera, Fanniidae) from China, with the description of one new species

One new junior synonym, Fannia tigripeda Xue, Wang&Li, syn. n. for Fannia stigi Rognes is established. To facilitate comparisons of the species, Fannia aethiops Malloch, Fannia ardua Nishida, Fannia discoculea Xue, Fannia ringdahlana Collin, Fannia postica (Stein), Fannia spathiophora Malloch, and Fannia stigi Rognes are redescribed and illustrated. The geographic distribution of the known Chinese species is updated.
