Distribution

A rare European species. Besides Britain the species was recorded only from Northern Europe: Finland ( Lundström 1909, as Neoempheria nigriceps ), Norway ( Økland 1999), Sweden ( Kjaerandsen et al. 2007), Estonia ( Lackschewitz 1937) and NW Russia ( Ostroverkhova and Stackelberg 1988, Chandler 2004). However, that Russian ("Northwest") record given by Ostroverkhova & Stackelberg ( Ostroverkhova and Stackelberg 1988) may actually refer to the Estonian record given by Lackschewitz ( Lackschewitz 1937). A few old Finnish records are mainly from southern Finland; from Åland archipelago and a few mainland sites not far from the Baltic coast (Lohja [holotype, Lundström 1909] Karjalohja, Helsinki, Espoo, Pietarsaari). The new Finnish record is from a much more northern area, SW Lapland (mid boreal vegetation zone). Reported here for the first time from the Republic of Karelia.

Ecology

Although the species is very rarely caught, the available records suggest that the species could be restricted to pristine forests. New findings from Russian Karelia are from herb-rich spruce dominated forest on the SE shore of Lake Ladoga. The sampling locality in SW Lapland (Ylitornio) is a spruce mire dominated by Vaccinium vitis-idaea on the ground layer, adult specimens were collected around a fallen spruce. Larval microhabitats are not perfectly known. Rearing records are available only from Norway where Økland ( Økland 1999) collected Eudicrana nigriceps with eclector traps over ground vegetation in three different substrates: (1) patch of Eu-Piceetum ground vegetation, (2) wet moss carpet on steep rock in Eu-Piceetum woodland, (3) mineral soil exposed by windfelling of Picea abies .

Conservation

Red-listed in Finland (EN, Penttinen et al. 2010).
