Black fungus-gnats in deciduous forest habitat in northern Europe, with the description of <i>Bradysia arcula</i> sp. n. (Diptera: Sciari…
2007
The sciarid fauna of a deciduous forest in Kivijärvi Nature Reserve, southern Finland, was studied. In all, 58 species were found in a material of 247 specimens, collected with Malaise traps. The material included the following species new to the Finnish and North European fauna: Corynoptera postforcipata Rudzinski, Leptosciarella juniperi (Mohrig & Blasco-Zumeta), Leptosciarella subcoarctata Mohrig&Menzel, Leptosciarella yerburyi (Freeman), Phytosciara macrotricha (Lengersdorf) and Sciara nursei Freeman. Bradysia arcula sp. n., found also in two other localities in Finland, is described, and a key to the Finnish species of the Bradysia praecox group is provided
A survey of the function of the lethal kettle traps of Arisaema (Araceae), with records of pollinating fungus gnats from Nepal
2000
Abstract Evidence from recent research combined with an evaluation of the literature indicates that Arisaema is adapted to pollination by fungus gnats. It apparently shares this peculiarity among aroids only with the distantly related genus Arisarum . In addition to previous records from Japan and North America, systematic collections from nine Arisaema species during several expeditions in the Himalayas in Nepal showed that, although other less efficient insect groups may participate, the nematoceran families Mycetophilidae and Sciaridae are the principal pollen vectors; they best fit the pollination apparatus of the mainly (para)dioecious kettle trap blossoms. A total of 16 fungus gnat ge…
Sciaridae (Diptera) from central Finland: faunistics and taxonomy
2005
Sciaridae (Diptera) from forest and mire habitats from three localities in central Finland were identified. The material consisted of 609 specimens belonging to 106 species. The following species were found as new to Finland: Bradysia subbetuleti, B. submoesta, B. subscabricornis, Corynoptera fera, C. furcifera, C. saetistyla, C. subsedula, Cratyna spiculosa, Leptosciariella helvetica, Lycoriella micria, Pseudolycoriella brunnea, P. nodulosa, Scatopsciara neglecta, Trichosia glabra and Sciara sp. n. (Menzel & Salmela, in prep.) and Ctenosciara exigua sp. n. The latter is described as new to science. Bradysia subbetuleti, Leptosciariella atricha, Leptosciariella tuberculigera and Lycorie…
