Nematus dolichurus Thomson, 1871: 164. Described: ♀, ♂. Lectotype, ♀, designated by Kopelke (1990b), MZLU [examined]. Type locality: Sweden, Jämtland, Skalstugan.
Pontania dolichura: Konow (1890).
Pontania (Pontania) dolichura: Viitasaari & Vikberg (1985).
Nematus (Pontania) dolichura: Zhelochovtsev (1988).
Euura dolichura: Shinohara & Hara (2015).
Pontania lapponicola Kopelke, 1994: 138 –140. Described: ♀, ♂, gall, recorded host: Salix lapponum. Holotype, ♀, SMF [examined]. Type locality: Norway, Nordland, Polar Circle B. Synonymy by Vikberg & Malinen (2012).
Variability. Female: Body length: 2.8–4.0mm. Male: 2.6–3.6mm. Vikberg & Malinen (2012) discuss variability, perhaps related to different geographic provenance, in the structure of the lancet. Total number of specimens examined: 7.
Genetic data. COI barcode not clearly distinguishable from others of this group, except perhaps E. virilis. Bionomics. Host plants: Salix lapponum (Kopelke 1994, Vikberg & Malinen 2012). Biology: Kopelke (1994). Distribution. Central Europe (Czech Republic, Giant Mountains: Beneš 2013), North Europe (Scotland, Scandinavia, Finland: Liston et al. 2012, Vikberg & Malinen 2012). Possibly North America (Benson 1962). Occurrence in Sweden: published records; Jämtland (Kopelke 1990b, Vikberg & Malinen 2012).
Euura femoralis (Cameron, 1876) comb. nov.
Nematus femoralis Cameron, 1876b: 295 –299. Described: ♀, ♂, larva, gall, recorded host: Salix ? laurina. Syntypes: ♀, ♂. Lectotype, ♀, designated by Vikberg & Malinen (2012), BMNH [examined]. Type locality: Scotland, Perthshire, Rannoch.
Pontania femoralis: Vikberg & Malinen (2012).
Pontania robbinsi Benson, 1935: 26 –27. Unnecessary replacement name for N. femoralis Cameron, which Benson wrongly treated as unavailable. As stated by Vikberg & Malinen (2012), the lectotype designation by Kopelke (1990b) is invalid (ICZN 1999: 72.4.4, 72.7): the lectotype of N. femoralis Cameron is also the lectotype of its objective junior synonym P. robbinsi.
Pontania dolichura: Kopelke (1990b), Kopelke (1994); misidentification.
Variability. Female: Body length: 3.0– 3.9mm. Male: 2.8–3.6mm. Total number of specimens examined: 4. Genetic data. COI barcode not clearly distinguishable from others of this group, except perhaps E. virilis. Bionomics. Host plants: Salix phylicifolia (Kopelke 1994). Biology: Kopelke (1994).
Distribution. North Europe (N. England, Scotland, Scandinavia, Finland, N. W. Russia: Liston et al. 2012, Vikberg & Malinen 2012, Zinovjev 1999). Occurrence in Sweden: published records; Torne Lappmark (Kopelke 1994); galls of the dolichura group found on S. phylicifolia at Hällefors, Västmanland (Vikberg & Malinen 2012) were probably caused by this species. Material examined: Lycksele Lappmark.
Euura glaucae (Kopelke, 1994) comb. nov.
Pontania glaucae Kopelke, 1994: 135 –136. Described: ♀, ♂, gall, recorded host: Salix glauca. Holotype, ♀, SMF [examined]. Type locality: Norway, Nordland, Korgen.
Variability. Female: Body length: 3.2–4.2mm. Male: 3.2–4.3mm. Total number of specimens examined: 4. Genetic data. COI barcode not clearly distinguishable from others of this group, except perhaps E. virilis. Bionomics. Host plants: Salix glauca (Kopelke 1994). Biology: Kopelke (1994).
Distribution. North Europe: Norway (Kopelke 1994), Finland (north to Utsjoki: Vikberg & Malinen 2012). Noblecourt (2004) and Taeger et al. (2006) listed glaucae in France, but according to T. Noblecourt [personal communication by email; translated]: " Pontania glaucae does not belong to the fauna of France: it was a mistake on my part in the interpretation of the synonymy". Occurrence in Sweden: published records; Torne Lappmark (Julin 1936; as Pontania femoralis on Salix glauca).
Euura nigricantis (Kopelke, 1986) comb. nov.
Pontania nigricantis Kopelke, 1986: 52 –58. Described: ♀, ♂, larva, gall, recorded host: Salix nigricans. Holotype, ♀, SMF [examined]. Type locality: Austria, Tirol, Zillertaler Alpen, Vorderlanersbach.
Variability. Female: Body length: 2.6–3.7mm. Male: 2.9–3.8mm. Total number of specimens examined: 8. Genetic data. COI barcode not clearly distinguishable from others of this group, except perhaps E. virilis. Bionomics. Host plants: Salix myrsinifolia (Kopelke 1994). Biology: Kopelke (1986, 1994).
Distribution. Central Europe (Alps: Kopelke 1994) and North Europe (Scotland, Scandinavia, Finland: Liston et al. 2012, Vikberg & Malinen 2012). Occurrence in Sweden: published records; Torne Lappmark (Kopelke 1994). Material examined: Jämtland, Västerbotten, Lycksele Lappmark, Torne Lappmark.
Euura unigallae (Vikberg & Zinovjev, 2014) comb. nov.
Pontania unigallae Vikberg & Zinovjev, 2014: 10 –12. Described: ♀, ♂, gall, recorded host: Salix repens ssp. rosmarinifolia. Holotype, ♀, ZIN [examined]. Type locality: Russia, Leningrad oblast, 60 km S of St. Petersburg, River Suida.
Variability. Female: Body length: 2.6–3.6mm. Male: 2.4–3.5mm. Total number of specimens examined: 5. Genetic data. COI barcode not clearly distinguishable from others of this group, except perhaps E. virilis. Bionomics. Host plants: Salix repens ssp. rosmarinifolia (Vikberg & Zinovjev 2014). Biology: Vikberg & Zinovjev (2014). Galls usually occur singly, one per leaf blade.
Distribution. North Russia (St Petersburg area), Estonia (Vikberg & Zinovjev 2014). Occurrence in Sweden: not recorded, but presence possible.
