description
Notes on types and taxonomy. Genetic data supports the status of glabrifrons as a distinct species. Variability. Female: Body length: 3.6 – 5.6 mm. Upper outer and inner orbits brown lined to entirely black. Tegula brown to black. Pronotum black, rarely with pale margin. Male: 3.7 – 4.0 mm. Female and male: anterior and posterior edge of femur lined with black to femur nearly entirely black. Total number of specimens examined: 76. Genetic data. Although the short BOLD COI barcode sequence will not separate glabrifrons from the other eleven North European species with closely similar barcodes (acutifoliae, arcticornis, brevicornis, etc.), longer COI, and ITS 2 sequences are distinctive (Leppänen et al. 2014). Bionomics. Host plants: Salix lanata (Benson 1960 b). Biology: Barstad & Nilsson (2012, 2015), Olofsson & Strengbom (2000), Roininen et al. (2002). Distribution. Norway, Sweden, Finland and N. Russia (Taeger et al. 2006), W. Siberia,? E. Siberia and? N. Russian Far East (Zhelochovtsev & Zinovjev 1995). Occurrence in Sweden: published records; Jämtland (Benander 1969), Lule Lappmark (Coulianos & Holmåsen 1991), Lycksele Lappmark (Haris 2009), Torne Lappmark (Coulianos & Holmåsen 1991). The specimen tentatively identified by R. B. Benson as this species from Skåne, Kullaberg, mentioned by Benander (1966), is a misidentification of E. pedunculi (see Benander 1969). Material examined: Torne Lappmark.
description
Variability. Female: Body length: 2.4 – 4.8 mm. Outer and inner orbits extensively pale, or almost entirely black. Dorso-posterior margins of pronotum pale, to black. Femora entirely pale, to basally fuscous. Male: 2.9 – 4.9 mm. All femora partly black and metafemur nearly entirely so, to pro- and mesofemur black basally with metafemur entirely yellow. Total number of specimens examined: 20. Genetic data. The short BOLD COI barcode sequence will not separate collactanea from the other eleven North European species with closely similar barcodes (acutifoliae, arcticornis, brevicornis, etc.). Bionomics. Host plants: Salix repens repens, S. repens rosmarinifolia (Kopelke 2003 a, Vikberg & Zinovjev 2006). Biology: Hanapi & Askew (1991), Kopelke (1991).
distribution
Distribution. Central and North Europe, including the British Isles (Taeger et al. 2006), north to Lake Ladoga in Russian Karelia (Vikberg & Zinovjev 2006). Occurrence in Sweden: published records; Skåne (Wahlgren 1944, as Pontania viminalis on Salix repens), Halland (Andersson 1955), Öland (Benander 1966), Uppland (Coulianos & Holmåsen 1991). Material examined: Skåne. Euura glabrifrons (Benson, 1960) comb. nov.
