  • molecular phylogeny of the fungus gnat subfamilies gnoristinae and mycomyinae and their position within Mycetophilidae diptera
    Systematic Entomology, 2019
    Co-Authors: David Kaspřak, Peter H. Kerr, Andrea Tothova, Vit Sýkora, Jan Ševčík
    Abstract:

    The phylogeny of the fungus gnat family Mycetophilidae (Diptera) is reconstructed with a focus on the species-rich and taxonomically difficult subfamilies Gnoristinae and Mycomyinae. The multigene phylogenetic analyses are based on five nuclear (18S, 28S, CAD, MCS, ITS2) and four mitochondrial (12S, 16S, COI, CytB) gene markers. The analyses strongly support the monophyly of Mycetophilidae and the subfamilies Manotinae, Sciophilinae, Leiinae, and Mycomyinae, although Gnoristinae is paraphyletic with respect to Mycetophilinae. All the genera and groups of genera included are supported as monophyletic, except for Acomoptera Vockeroth, Boletina Staeger, Dziedzickia Johannsen, Ectrepesthoneura Enderlein, and Neoempheria Osten Sacken. Ancestral character state reconstructions were applied to two morphological features present in Gnoristinae and Mycomyinae (i.e. presence of setae on wing membrane and wing vein R4) in order to assess their evolution. The wing vein R4 appears as an unstable character, spread throughout different clades. A dated phylogeny of the family Mycetophilidae showed that most of the subfamilies of Mycetophilidae originated and diversified during the Cretaceous. The youngest subfamilies, originated in the Paleogene, appear to be Mycomyinae and Mycetophilinae.

    Co-Authors: Jan Ševčík
    Abstract:

    Abstract. A new species of Docosia Winnertz, 1863 (Diptera: Mycetophilidae), Docosia heikkii, sp.nov., is described from Doi Inthanon of northern Thailand. This is the first record of the principally Holarctic Docosia from the Oriental Region. The new species is characterized by its apically clouded wings with all the veins dark, vein ta being relatively short and oblique, long palpi, setose laterotergites, yellow coxae and peculiar male terminalia. It has a rather distinct position within the genus with some characters typical of the subfamily Gnoristinae rather than Leiinae

  • molecular phylogeny of fungus gnats diptera Mycetophilidae revisited position of manotinae metanepsiini and other enigmatic taxa as inferred from multigene analysis
    Systematic Entomology, 2013
    Co-Authors: Jan Ševčík, David Kaspřak, Andrea Tothova
    Abstract:

    The phylogeny of selected genera from four subfamilies of fungus gnats (Diptera: Mycetophilidae) – Manotinae, Leiinae, Sciophilinae and Gnoristinae (including Metanepsiini) – is reconstructed based on the combined analysis of five mitochondrial (12S , 16S , COI , COII , cytB) and two nuclear (28S , ITS2 ) gene markers. Results of the different analyses all support Manotinae as a monophyletic group, with Leiinae as the sister group. Allactoneura DeMeijere is nested in the monophyletic and strongly supported clade of Leiinae. The tribe Metanepsiini is revealed as paraphyletic and the genera Metanepsia Edwards and Chalastonepsia Soli do not appear to be closely related. The genera Docosia Winnertz, Ectrepesthoneura Enderlein, Novakia Strobl and Syntemna Winnertz were placed with a group of genera included traditionally in the Gnoristinae. The monophyly of Dziedzickia Johannsen and Phthinia Winnertz is not supported. The genera of Sciophilinae (excluding Paratinia Mik but including Eudicrana Loew) form a monophyletic group in the Bayesian model.

  • brachyradia a new genus of the tribe exechiini diptera Mycetophilidae from the oriental and australasian regions
    Raffles Bulletin of Zoology, 2012
    Co-Authors: Jan Ševčík, Jostein Kjaerandsen
    Abstract:

    Brachyradia, new genus, is proposed and described for two new species of the tribe Exechiini (Diptera: Mycetophilidae) from the Oriental and Australasian regions. The type species, Brachyradia asiatica, new species, is described from Thailand, Malaysia, and Indonesia (Sulawesi), and a second species, Brachyradia australis, new species, from Indonesia (Sulawesi) and Papua New Guinea. The systematic position of the new genus and the zoogeography of the tribe Exechiini are discussed. The new genus shows closest affi nities with Brevicornu with interconnections towards Cordyla, Neallodia, and Anatella. As the latter genera have been considered among the most primitive taxa of the tribe, Brachyradia may generate new and interesting questions about polarities of characters, direction of morphological transformations, and the zoogeographical origin of the Exechiini genera.

  • fungus gnats diptera sciaroidea of the gemer region central slovakia part 2 Mycetophilidae
    Acta Musei Silesiae: Scientiae Naturales, 2011
    Co-Authors: Jan Ševčík, Olavi Kurina
    Abstract:

    A total of 317 species of Mycetophilidae are recorded from the Gemer region in central Slovakia. The material was obtained mainly in the years 2008–2011 by means of Malaise traps and by individual collecting by the authors. A new species of Mycetophila Meigen, M. gemerensis sp. n., is described and additional 47 species are recorded as new to Slovakia. A new synonym is proposed: Mycetophila quadra Lundstrom, 1909 = M. chamberlini (Laffoon, 1957) syn. n.
