Euura reticulatae
Description
Euura reticulatae (Malaise, 1921)
Pontania reticulatae Malaise, 1921a: 109 –110. Described: ♀, ♂, larva, gall, recorded host: Salix reticulata. Lectotype, ♀, designated by Vikberg (2003), NHRS [NHRS-HEVA000003545; examined]. Type locality: Sweden, Torne Träsk area.
Pontania (Eupontania) reticulatae: Zinovjev (1985).
Pontania (Pontania) reticulatae: Viitasaari & Vikberg (1985).
Nematus (Pontania) reticulatae: Zhelochovtsev (1988).
Eupontania reticulatae: Vikberg & Zinovjev (2006).
Euura (Eupontania) reticulatae: Noblecourt (2016).
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as its host, its galls are different from E. reticulatae and it belongs to a different genetic branch (Nyman, unpublished).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.
