Pontania arctica ( MacGillivray, 1919) : Coulianos & Holmåsen (1991); misidentification.

Notes on types and taxonomy. Under the name Pontania arctica ( MacGillivray, 1919) this was for a time considered to be a Holarctic species (e.g. Beneš 1967, Zhelochovtsev & Zinovjev 1995). However, although the North American taxon also has S. reticulata as its host, its galls are different from E. reticulatae and it belongs to a different genetic branch (Nyman, unpublished). Vikberg (2003) placed arctica in the aquilonis group (here: subgroup). See there, under 'Species not occurring in northern Europe', regarding the nomenclature of the Nearctic taxon.

Variability. Female: Body length: 3.7–5.0mm. Male: 2.6–4.9mm. Upper outer orbits and lateral vertex slightly brown, to entirely black. Female and male: mesepisternum entirely smooth and shiny, to sculptured and matt on upper half. Tegula pale, to black. Total number of specimens examined: 34.

Genetic data. Cannot be identified using COI data, but is distinct in ITS2 sequences (Leppänen et al. 2014).

Bionomics. Host plants: Salix reticulata ( Malaise 1921a) . Biology: Beneš (1967), Malaise (1921a), Nyman & Julkunen Tiitto (2000), Roininen et al. (2002).

Distribution. Central Europe (Alps and Carpathians) and North Europe (Scandinavia) (Vikberg & Zinovjev 2006). Occurs only above, or North of, the tree line. Occurrence in Sweden: published records; Härjedalen, Hamra Mts ( Malaise 1921a), Jämtland ( Coulianos & Holmåsen 1991), Luleå Lappmark, Sarek Mts.; Torne Lappmark, Torne Träsk area ( Malaise 1921a). Material examined: Torne Lappmark.
