Recent noteworthy findings of fungus gnats from Finland and northwestern Russia (Diptera: Ditomyiidae, Keroplatidae, Bolitophilidae and Mycetophilidae)

Abstract New faunistic data on fungus gnats (Diptera: Sciaroidea excluding Sciaridae) from Finland and NW Russia (Karelia and Murmansk Region) are presented. A total of 64 and 34 species are reported for the first time form Finland and Russian Karelia, respectively. Nine of the species are also new for the European fauna: Mycomya shewelli Väisänen, 1984, Mycomya thula Väisänen, 1984, Acnemia trifida Zaitzev, 1982, Coelosia gracilis Johannsen, 1912, Orfelia krivosheinae Zaitzev, 1994, Mycetophila biformis Maximova, 2002, Mycetophila monstera Maximova, 2002, Mycetophila uschaica Subbotina & Maximova, 2011 and Trichonta palustris Maximova, 2002.

Eleven remarkable Diptera species, emerged from fallen aspens in Kivach Nature Reserve, Russian Karelia

Abstract Background In 2016, saproxylic Diptera associated with aspen (Populus tremula L.) logs were studied in the Kivach Nature Reserve, Russian Karelia, using trunk emergence traps. New information Eleven rare species of Diptera (families Limoniidae, Scatopsidae, Axymyiidae, Mycetophilidae, Sciaridae, Platypezidae, Syrphidae and Clusiidae) with poorly known distribution and ecology were recorded. For each species, basic diagnostic characteristics were provided along with the information on microhabitats. An attempt was also undertaken to outline possible associations with wood-decaying macrofungi using nonparametric correlation.
