Notes on types and taxonomy. See below (Genetic data).

Variability. Female: Body length: 3.2–6.2mm. Pronotum dorsally extensively pale, to completely black. Metafemora completely pale, to extensively fuscous. All abdominal sterna and downturned flanks of terga pale, to nearly wholly black. Male: 2.7–4.8mm. Female and male: inner and outer orbits, lateral vertex and supraclypeal area pale, to completely black. Total number of specimens examined: 17.

Genetic data. The short BOLD COI barcode sequence will not separate saliciscinereae from the other eleven North European species with closely similar barcodes ( acutifoliae, arcticornis, brevicornis, etc.), but differences in ITS2, and longer COI sequences, support its status as a separate species (Leppänen et al. 2014).

Bionomics. Host plants: Salix lapponum (Vikberg & Zinovjev 2006), S. lapponum × phylicifolia (Kopelke 1991) . Biology: Kopelke (1991), Nyman & Julkunen Tiitto (2000), Roininen et al. (2002).

Distribution. North Europe (Scotland, Scandinavia, Finland, N. Russia), France (Massif Central: Lacourt 2001) possibly also E. Siberia and the northern parts of the Russian Far East (Zhelochovtsev & Zinovjev 1995). Occurrence in Sweden: published records; Jämtland, Torne Lappmark (Benander 1969). Material examined: Jämtland.
