First contribution on distribution, abundance, and species richness of blowfly species (Diptera) of Isparta Province with five new records for the Turkish fauna

Despite the increasing importance of species richness of blowfly fauna and their environmental, medical, and agricultural importance in the world they are poorly studied in Turkey. This study was carried out in 2014 and 2015 to determine the distribution, abundance, and species richness of blowfly species in Isparta Province of Turkey. A total of 15 species (10 from Calliphoridae, 4 from Polleniidae, and 1 from Rhiniidae) were identified from 13 different localities. The adult specimens were obtained from areas of organic and decayed organic matters, waste and dumpsite, surrounding waste water deposits, and flowering plants. While all the species were new for Isparta, Bellardia tatrica (Enderlein, 1933), Calliphora subalpina (Ringdahl, 1931), Lucilia silvarium (Meigen, 1826), Melinda gentilis (Robineau-Desvoidy, 1830) and Pollenia griseotomentosa (Jacentkovsky, 1944) were determined as new records for the Turkish fauna. According to the study results, the highest levels of blowfly species richness will be mainly focused in the eastern part of Isparta Province. Chrysomya albiceps and Lucilia sericata were determined as the most common species in the study.Peer reviewe

Revision of the Merodon serrulatus group (Diptera, Syrphidae)

The phytophagous hoverfly genus Merodon Meigen, 1803 (Diptera, Syrphidae), which comprises more than 160 species distributed in Palaearctic and Afrotropical regions, can be differentiated into multiple groups of species that harbor high levels of hidden diversity. In this work, the serrulatus species group of Merodon is revised, providing an illustrated key to species, a detailed discussion on the taxonomic characters and a morphological diagnosis, including also the first data about the preimaginal morphology of this species group. The study includes characteristics of the 13 species of the M. serrulatus group, along with the available distributional data. Moreover, descriptions are provided for seven new species, namely M. defectus Vujic, Likov & Radenkovic sp. nov., M. disjunctus Vujic, Likov & Radenkovic sp. nov., M. medium Vujic, Likov & Radenkovic sp. nov., M. nigrocapillatus Vujic, Likov & Radenkovk sp. nov., M. nigropunctum Vujic, Likov & Radenkovic sp. nov., M. opacus Vujic, Likov & Radenkovk sp. nov., and M. trianguloculus Vujic, Likov & Radenkovk sp. nov. In addition, the taxa M. serrulatus (Wiedemann in Meigen, 1822), M. bequaerti Hurkmans, 1993, M. birsutus Sack, 1913, M. kawamurae Matsumura, 1916, M. sacki (Paramonov, 1936) and M. sophron Hurkmans, 1993 are redefined and redescribed. Following a detailed study of the type material sourced from different entomological collections, the status of all available taxa related to M. serrulatus is revised and a new synonymy is proposed: M. tener Sack, 1913 syn. nov. (junior synonym of M. serrulatus). The identity of M. trizonus (Szilady, 1940) could not be assessed as the type specimens are lost. Thus, the name M. trizonus is considered as nomen dubium. The monophyly and composition of this species group are assessed through Maximum Parsimony and Maximum Likelihood analyses of the mitochondrial COI and nuclear 28S rRNA gene sequences.Peer reviewe
