Euura plicadaphnoides

description: Euura plicadaphnoides (Kopelke, 2007)
Phyllocolpa plicadaphnoides Kopelke, 2007a: 97 –99. Described: ♀, ♂, gall, recorded host: Salix daphnoides. Holotype, ♀, SMF [examined]. Type locality: Austria, Salzburg, Obertauern.
Euura plicadaphnoides: Liston (2015).
Variability. Female: Body length: 3.4–5.5mm. Outer margin of inner orbits partly black to narrowly but continuously pale. Upper outer orbits partly pale to outer orbits continuously pale. Ratio of length flagellomere 2 / height of eye 1.00-1.03. Male: 3.2–4.3mm. Upper outer orbits and lateral vertex clearly pale to almost black. Total number of specimens examined: 11.
Genetic data. COI barcodes of species of this complex, as well as E. oblita, are highly similar, and not useful for identification.
Similar species. Females are most similar to the other segregates with typically extensively pale orbits: E. polita, E. prussica.
Bionomics. Host plants: Salix daphnoides,? S. acutifolia (Kopelke 2007a). Biology: Kopelke (2007a).
Distribution. Published records are from Alpine areas of Central Europe (Austria and Switzerland: Kopelke 2007a), as well as lowland areas in the Czech Republic (Beneš 2015a) and Germany (Liston 2015). Kopelke (2007a) noted that galls similar to those on S. daphnoides were found on S. acutifolia in Lithuania, but no specimens were reared. Occurrence in Sweden: no records, but should be looked for where its host(s) occurs.
Euura plicalapponum (Kopelke, 2007) comb. nov.
Phyllocolpa plicalapponum Kopelke, 2007a: 100 –101. Described: ♀, ♂, gall, recorded host: Salix lapponum. Holotype, ♀, SMF [examined]. Type locality: Norway, Finnmark: S.- Varanger, Faerdesmyra.
Variability. Female: Body length: 3.5–4.4mm. Ratio of length flagellomere 2 / height of eye 0.84-0.93. Male: not examined. Female and male: too few specimens were examined to allow an assessment of variability. Total number of specimens examined: 5.
Genetic data. COI barcodes of species of this complex, as well as E. oblita, are generally highly similar, and not useful for identification. However, the single sequence available for E. plicalapponum differs markedly from the sequences of the other members of the complex. The tissue sample was from a larva, which was perhaps not correctly identified.
Similar species. Females are most similar to the other segregates with typically extensively dark orbits: E. ischnocera, E. plicaphylicifolia.
Bionomics. Host plant: Salix lapponum (Kopelke 2007a). Biology: Kopelke (2007a).
Distribution. Only recorded from Scotland (Liston et al. 2012) and Norway (Kopelke 2007a). Apparently a rather uncommon species: many of the specimens from Norway identified by Kopelke as this species are E. acutiserra. Occurrence in Sweden: no published records, but can be assumed to be present.
Euura plicaphylicifolia (Kopelke, 2007) comb. nov.
Phyllocolpa plicaphylicifolia Kopelke, 2007a: 101 –102. Described: ♀, ♂, gall, recorded host: Salix phylicifolia. Holotype, ♀, SMF [examined]. Type locality: Norway, S.- Trøndelag: Dovrefjell, Grønbakken.
Variability. Female: Body length: 2.9–4.4mm. Ratio of length flagellomere 2 / height of eye 0.79-1.04. Male: 3.6– 4.1mm. Female and male: small brown area on lateral vertex may be absent. Extent of pale on lower inner orbits and malar space variable. Distal ca. half of metafemur pale to nearly whole femur black. Total number of specimens examined: 5.
Genetic data. COI barcodes of species of this complex, as well as E. oblita, are highly similar, and not useful for identification.
Similar species. Females are most similar to the other segregates with typically extensively dark orbits: E. ischnocera, E. plicalapponum.
Bionomics. Host plant: Salix phylicifolia (Kopelke 2007a). Biology: Kopelke (2007a).
Distribution. Only previously recorded from Scotland (Liston et al. 2012), and Norway (Kopelke 2007a). Occurrence in Sweden: no published records, but can be assumed to be present.
