Euura polita (Zaddach, 1883)

Nematus politus Zaddach, 1883 [in Brischke 1883a]: pl. I(7):14 [larva, host]; text description in Brischke 1884: 167–168 [♀, ♂]. Described: ♀, ♂, larva, recorded host: Salix helix . Neotype, ♀, designated by Kopelke (2007a), SMF [examined]. Type locality: Germany, Hesse: Wetterau, Ortenberg I ( Nidder).

Phyllocolpa polita: Kopelke (2007a) .

Euura polita: Prous et al. (2014) .

Nematus sieboldii Zaddach, 1884 [in Brischke 1884]: 171–172. Described: ♀. Syntypes stated by Zaddach to have been received from ZMHUB, but have not been located there (Kopelke 2007a). Type locality: Danzig. Synonymy with Phyllocolpa polita by Kopelke (2007a).

Pontania leucapsis var. connata Enslin, 1915: 347 . Described: adult, sex not specified. Lectotype, ♀, designated by Kopelke (2007a), ZSM [examined]. Type locality: Germany, Gotha. Synonymy with Phyllocolpa polita by Kopelke (2007a).

Variability. Female: Body length: 2.8–4.0mm. Ratio of length flagellomere 2 / height of eye 0.88-1.00. Male: 2.9– 3.8mm. No significant variability in colour pattern of specimens examined. Total number of specimens examined: 12.

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. plicadaphnoides, E. prussica .

Bionomics. Host plants: Salix purpurea (Kopelke 2007a), Salix purpurea × silesiaca (Beneš 2015a) . Biology: Beneš (1968a; as Phyllocolpa leucapsis), Kopelke (2007a).

Distribution. Mainly in Central Europe (Kopelke 2007a), but also Greece: 1 fem., 11.5.2007, Nom. Evritania, Karpenisi E 4km, Agios Nikolaos, 900 m., 38.91666°N 21.78333°E, leg. Liston (SDEI) [first record from Greece]. Occurrence in Sweden: published records; Skåne (Benander 1966, as Pontania leucapsis reared from Salix purpurea), Västergötland (Wahlgren 1960, as galls of Pontania leucapsis on S. purpurea).
