Described: ♀ . Holotype , ♀ , ZSM [examined]. Type locality: France , Corsica , Corti , Santo Pietro di Venacu. Tubpontania cyrnea : Vikberg (2010b) . Euura cyrnea : Beneš (2015b) . Pontania joergenseni Enslin, 1916 : 17 . Described: [name proposed for specimens of Pontania pedunculi Konow nec Hartig]. Lectotype , ♀ , designated by Zinovjev & Vikberg (1999) , SDEI [examined]. Type locality: Germany , Mecklenburg- Vorpommern , Teschendorf. Primary homonym of Pontania joergenseni Strand, 1908 . Synonymy with P. cyrnea by Vikberg (2010b) . Pontania (Phyllocolpa) joergenseni : Viitasaari & Vikberg (1985) . Nematus ( Pontania ) joergenseni : Zhelochovtsev (1988) . Phyllocolpa anomaloptera : Kopelke (2007c) ; misidentification. Notes on types and taxonomy. P. cyrnea . A technical problem concerning the lancet of the holotype was discussed by Vikberg (2010b: 7) . Variability. Female: Body length: 3.4–5.2mm . Male: 3.5–4.2mm . Total number of specimens examined: 15. Genetic data. The COI barcode of the only sequenced specimen of E. cyrnea (paratype from Corsica) shares the same BIN as five E. purpureae from Austria, France, and Morocco. Nevertheless, divergence of E. cyrnea from the nearest E. purpureae amounts to about 1.9%. Bionomics. Host plants: Salix caprea ( Kopelke 2007c , Vikberg 2010b ). Biology: Beneš (2015a) , Vikberg (2010b) , Zinovjev & Vikberg (1999: as joergenseni ) . The galls illustrated by Mol (2013: fig. 6) were definitely not caused by E. cyrnea : they show the characters typical of the ischnocera complex of the E. oblita group. Distribution. South, Central and North Europe north to Nordland in Norway ( Kopelke 2007c ). Occurrence in Sweden : published records; Skåne , Småland (Haris 2009), Bohuslän ( Vikberg 2010b ), Närke (Haris 2009). Material examined: Småland, Västmanland . Euura nitidinota (Vikberg, 2010) comb. nov. Tubpontania nitidinota Vikberg, 2010b : 20 –22. Described: ♀ , ♂ , larva, gall, recorded host: Salix phylicifolia . Holotype , ♀ , FMNH [examined]. Type locality: Finland , North Savo , Nilsiä , Syvärinranta. Variability. Female: Body length: 2.9–4.5mm . Male: unknown. Total number of specimens examined: 4. Genetic data. None available. Similar species. Resembles E. nudipectus in external morphology. The lancets ( E. nudipectus , Fig. 38 ; E. nitidinota , Fig. 39 ) are also very similar, except that the distal cypsellae are shallower and less rounded in E. nitidinota . Bionomics. Host plants: Salix phylicifolia is definitely a host, but possibly other willow species may also be used ( Vikberg 2010b ). Biology: no data available. Distribution. Only known from North Europe ( Sweden , Finland , Russia ) ( Vikberg 2010b ). Occurrence in Sweden : published records; Lycksele lappmark ( Vikberg 2010b ). Euura nudipectus ( Vikberg, 1965 ) comb. nov. Pontania nudipectus Vikberg, 1965 : 54 –57. Described: ♀ , ♂ , larva, gall, recorded host: Salix phylicifolia . Holotype , ♀ , FMNH [examined]. Type locality: Finland , PK, Kitee. Pontania ( Phyllocolpa ) nudipectus : Viitasaari & Vikberg (1985) . Nematus ( Phyllocolpa ) nudipectus : Zhelochovtsev (1988) . Phyllocolpa nudipectus : Kopelke (1999) . Tubpontania nudipectus : Vikberg (2010b) . Pontania arctophilae : Vikberg (1962) ; misidentification. Variability. Female: Body length: 3.3–4.2mm . Male: 2.9–3.8mm . Total number of specimens examined: 12. Genetic data. Nearest COI barcode neighbour is E. purpureae , with about 4.3% divergence. Similar species. Resembles E. nitidinota in external morphology. The lancets ( E. nudipectus , Fig. 38 ; E. nitidinota , Fig. 39 ) are also very similar, except that the distal cypsellae are deeper and more rounded in E. nitidinota . Bionomics. Host plants: Salix phylicifolia ( Kopelke 2007c , Vikberg 2010b ). Biology: Vikberg (2010b) , Zinovjev & Vikberg (1999) . Distribution. Only recorded in North Europe: Norway , Sweden , Finland , northern Russia ( Vikberg 2010b ), and Estonia (1 Fem., Raplamaa , Jõeääre, 30 m . , +58.81700 +24.45800, 0 8.06.2015, M. Prous, SDEI). Occurrence in Sweden : published records; Jämtland , Västerbotten , Norrbotten , Torne Lappmark (Haris 2009). Material examined: Härjedalen, Torne Lappmark.
