Euura acutiserra (Lindqvist, 1949) Pontania acutiserra Lindqvist, 1949: 66 –68. Described: ♀, ♂. Holotype, ♀, FMNH [examined]. Type locality: Finland, Utsjoki, Outakoski. Phyllocolpa acutiserra: Benson (1960a). Pontania (Phyllocolpa) acutiserra: Viitasaari & Vikberg (1985). Nematus (Phyllocolpa) acutiserra: Zhelochovtsev (1988). Euura acutiserra: Prous et al. (2014). Variability. Female: Body length: 3.7–4.0mm. Male: 3.6–4.0mm. Female and male: no significant variability in colour pattern. Total number of specimens examined: 17. Genetic data. COI barcodes in BOLD of four E. acutiserra specimens from Norway and Finland with approx. 0.2% intraspecific variability diverge by a minimum of about 3.0% from the morphologically most similar north European species, E. leucapsis. The European E. acutiserra barcodes nest within a BIN containing sequences of seven Canadian specimens under the name Phyllocolpa excavata: the most similar of these sequences to a European specimen differs by about 1.0%. Bionomics. Host plants: Salix lapponum (Kopelke 2007b),? S. glauca (Vikberg 1970, Zinovjev 1999). The record from S. glauca in Vikberg (1970) is based on a single specimen reared by E. Peltonen. Possibly the Salix species was misidentified, or S. glauca is a rarely used host. Males of E. acutiserra are rare (Vikberg 1970, Kopelke 2007b): apart from the single male paratype, we examined two males reared by Kopelke. Biology: Kopelke (2007b), Zinovjev & Vikberg (1998). Distribution. North Europe (Kopelke 2007a), possibly including Scotland (Benson 1958; but the identity of the single specimen needs checking, because neither recorded host is known at its collection site), Russia (Yakutia: Popov 2011). Recorded in Canada (Benson 1962), but determination requires checking; see also above, under Genetic data. Occurrence in Sweden: published records; Jämtland (Haris 2009), Västerbotten (Kopelke 2007b), Lycksele Lappmark, Torne Lappmark (Haris 2009). Material examined: Hälsingland, Jämtland, Lule Lappmark, Norrbotten, Torne ...
