Peyerimhoffia jaschhoforum (Diptera, Sciaridae), a new deadwood inhabiting species from Canada

Abstract

A new species of black fungus gnat from Canada, Peyerimhoffia jaschhoforum sp. n., is presented with a description, illustrations, biotope information and a brief discussion of the placement and concept of the genus Peyerimhoffia. P. jaschhoforum is characterized by a unique gonostylar structure where the apex is hollowed but not enclosed and contains a mass of mega setae housed within. P. jaschhoforum was reared from decomposing jack pine (Pinus banksiana Lamb.) deadwood using both in-situ and ex-situ photoeclectors. We documented three additional specimens originating from Fennoscandia that resemble P. jaschhoforum but differ based on a broader tegmen, placement of setigerous papillae behind the tegmen and the fused intercoxal area. Based on this, these specimens are assigned to a new subspecies, Peyerimhoffia jaschhoforum fennoscandica ssp. n.

The Genus Spinopygina gen. nov. (Diptera, Sciaridae) from Western North America: Preliminary Molecular Phylogeny and Description of Seven New Species

“…Of the Holarctic fauna of Sciaridae, the Nearctic region is much less studied than the Palaearctic fauna. Mohrig et al [ 13 ] in their revision listed 166 valid species from the Nearctic region (excluding Greenland), and subsequent authors [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ] have added 70 new species,making a total of 236 known species in the Nearctic to date. The number of known Palaearctic species is much higher, about 2000.…”

Peyerimhoffia vagabunda – new sciarid species (Sciaridae, Diptera) for the entomofauna of Ukraine

“…It has been recorded in 20 European countries (Luxemburg, Germany, Sweden, France, Spain, Finland, Great Britain (Lundy Is. ), Italy, Norway, the Netherlands, Albania, Austria, Bulgaria, the Czech Republic, the Danish mainland, the Greek mainland, Hungary, Ireland, Slovakia, Switzerland) and in Asia (Kazakhstan, Altai and Primorsky Krai) (Donisthorpe, 1913;Edwards, 1925;Tuomikoski, 1960;Mohrig & Röschmann, 1994;Mohrig & Blasco-Zumeta, 1995;Komarova, 2003;Menzel et al, 2006;Sataeva, 2006;Komarov, 2011;Heller & Weber, 2013;Menzel & Heller, 2013;Deady et al, 2014;Shi et al, 2014). The range of P. vagabunda has disjunctions between the European and Asian parts.…”
