Euura anomaloptera

description: Euura anomaloptera (Förster, 1854)
Nematus anomalopterus Förster, 1854a: 308 –309. Described: ♀. Lectotype, ♀, designated by Kopelke (2007a), ZSM [examined]. Type locality: Germany, near Aachen.
Phyllocolpa anomaloptera: Kopelke (2007c).
Tubpontania anomaloptera: Vikberg (2010b).
Euura anomaloptera: Prous et al. (2014).
Amauronematus maidli Zirngiebl, 1937: 336 –337. Described: ♀. Holotype, ♀, NHMW [examined]. Type locality: Istria. Synonymised with Phyllocolpa anomaloptera by Kopelke (2007c).
Nematus (Pontania) tuberculatus Benson, 1953: 151 –152. Described: ♀, ♂, recorded host:? Salix atrocinerea. Holotype, ♀, BMNH [examined]. Type locality: Ireland, Cavan, Lough Mentis. Synonymy with N. anomalopterus by Vikberg (2010b).
Pontania tuberculata: Benson (1958).
Pontania (Phyllocolpa) tuberculata: Vikberg (1982).
Variability. Female: Body length: 3.0– 4.9mm. Male: 3.0– 4.4mm. Total number of specimens examined: 24.
Genetic data. Nearest neighbours in COI barcoding are E. cyrnea and E. purpureae. The latter share the same BIN, diverging by a minimum of 5.6% from E. anomaloptera. The seven barcoded E. anomaloptera specimens have two apparent haplotypes, diverging by a minimum of 2.4%. Both were represented in Swedish material: haplotype 1 comprised two females from Härjedalen and Torne Lappmark (Stordalen); haplotype 2 comprised five females from Torne Lappmark, Abisko NP, 390–900m (four) and France, Departement Ariège (one). No morphological differences were correlated with the apparent genetic dichotomy.
Bionomics. Host plants: In northern Europe Salix hastata (Kopelke 2007c), S. phylicifolia and S. starkeana (Zinovjev & Vikberg 1999, Vikberg 2010b) have been recorded as definite hosts. These willow species do not occur at the type localities of N. anomalopterus, A. maidli or N. tuberculatus. Benson (1953) suggested S. atrocinerea as the probable host at the type locality of N. tuberculatus. Zinovjev (1999) and Zinovjev & Vikberg (1999) list several other willow species which are possibly hosts in the East Palaearctic. The host spectrum of E. anomaloptera is unusually wide, so that further investigation seems called for. Biology: Vikberg (2010b), Zinovjev & Vikberg (1999: as tuberculata).
Distribution. South, Central and North Europe (Taeger et al. 2006),? northern Russian Far East (Zhelochovtsev & Zinovjev 1995). Occurrence in Sweden: published records; Norrbotten (Haris 2009), Torne Träsk area (Vikberg 2010b). Material examined: Härjedalen, Jämtland, Norrbotten, Lule Lappmark, Torne Lappmark.
Euura crassispina (Thomson, 1871) comb. nov.
Nematus crassispina Thomson, 1871: 164 –165. Described: ♀. Lectotype, ♀, designated by Zinovjev & Vikberg (1999), MZLU [examined]. Type locality: Sweden, Jämtland, Skalstugan.
Pontania crassispina: Konow (1890).
Pontania (Phyllocolpa) crassispina: Viitasaari & Vikberg (1985).
Pontania (Pontania) crassispina: Zinovjev (1993b).
Phyllocolpa crassispina: Kopelke (2007c).
Tubpontania crassispina (Thomson, 1871): Vikberg (2010b).
Variability. Female: Body length: 3.1–4.3mm. The single female which has so far been reared from Salix hastata differs slightly in details of valvula 3 setation from those reared from S. glauca (Vikberg 2010b). Male: unknown. Total number of specimens examined: 9.
Genetic data. Of species of this group for which COI barcodes are currently available, the nearest neighbour is E. anomaloptera, at a minimum of 7.1% divergence.
Bionomics. Host plants: Salix glauca, occasionally S. hastata (Vikberg 2010b). Biology: Vikberg (2010b), Zinovjev & Vikberg (1999).
Distribution. The only definite records are from Norway, Sweden, Finland and northern European Russia (Vikberg 2010b), but possibly also occurs in northern parts of the Russian Far East (Zhelochovtsev & Zinovjev 1995). Occurrence in Sweden: published records; Jämtland (Zinovjev & Vikberg 1999), Torne Lappmark (Haris 2009). Material examined: Jämtland, Lule Lappmark, Torne Lappmark.
Comments. A supposed male of this species described by Zinovjev & Vikberg (1999) was probably misidentified (Vikberg 2010b).
