Additions to the list of Finnish Bibionomorpha (Diptera, Nematocera)

Abstract

A total of 12 gnat species are reported for the first time from Finland (3 Cecidomyiidae, 1 Keroplatidae, 8 Mycetophilidae), and the occurrence of Macrocera nigropicea Lundström in Finland is verified. All material was collected from the Finnish Lapland, mainly from the north boreal ecoregion. Two of the recorded species are likely to be pyrophilous, associated with forest fire sites. A photo of the ventral appendage of the gonocoxite of Brevicornu setigerum Zaitzev is provided for the first time. The male hypopygium of Mycetophila haruspica Plassmann is redescribed.

Fungus gnats (Diptera: Bolitophilidae, Diadocidiidae, Keroplatidae, Mycetophilidae) in the Kostomuksha State Nature Reserve, Russia

“…The male from the Kostomuksha State Nature Reserve had been left unidentified for a long time due to a quite uninformative original description. This issue was solved after photos of male genitalia were published by Salmela & Kaunisto (2015). It is reported here for the first time from Karelia and Russia.…”

“…The record of Mycomya obliqua as a new species for the Palaearctic region is remarkable, but not something extraordinary. As our knowledge of the regional fauna increases, more and more Nearctic species are being found (Polevoi, 2010;Jakovlev et al, 2014;Salmela & Kaunisto, 2015;Polevoi & Salmela, 2016). It becomes clear that a substantial part of fungus gnats occurring in the northern boreal zone have a circumpolar range.…”

“…Fungus gnats are well known in Scandinavian countries, largely due to growing interest since the beginning of the XXI century. Nowadays, the number of known species exceeds 750 in Finland and Sweden Jakovlev, 2014), and 600 (only for the family Mycetophilidae) in Norway (Søli & Rindal, 2012), and may reach around 1000 in the whole of Fennoscandia (Salmela & Kaunisto, 2015).…”

New taxonomic and faunistic records of fungus gnats (Insecta, Diptera) from Montenegro, Romania, and Serbia

“…The species is probably very widespread in Europe (Chandler 2013) and has already been reported by Pârvu (2003Pârvu ( , 2004a from Romania. Stigmatomeria crassicornis is, however, close to S. obscura (Winnertz, 1864), a species that had been for decades considered as a junior synonym of S. crassicornis (see Kjaerandsen et al 2007, Salmela andKaunisto 2015). Pârvu (2003) reported 2 females from Maramureș Depression, and the sex of the specimen examined from Piatra Craiului National Park was not specified (Pârvu 2004a).…”

“…Romania: Vulcan Mt., (Kjaerandsen 2012). However, a recently described species, M. gemerensis Ševčík & Kurina 2011, is close to M. lastovkai, and thus older records of the latter species should be verified due to possible confusion of these 2 taxa (Salmela and Kaunisto 2015). Immature stages of M. lastovkai are unknown.…”
