Described: ♀ . Lectotype , ♀ , designated by Vikberg & Zinovjev (2006), ZSM [examined]. Type locality: Germany , near Aachen. Eupontania brevicornis : Vikberg & Zinovjev (2006) . Pontania ( Eupontania ) brevicornis : Taeger et al. (2010) . Euura brevicornis : Beneš (2015b) . Nematus foersteri André, 1880 : 152 , unnecessary replacement name for N. brevicornis . Nematus congruens Förster, 1854a : 346 –347. Described: ♂ . Lectotype , ♂ , designated by Kopelke (1991) , ZSM [examined]. Type locality: Germany , near Aachen. Synonymy with E. brevicornis by Vikberg & Zinovjev (2006). Pontania carpentieri Konow, 1907 : 133 –134. Described: ♀ , ♂ ; no type material has been located in the SDEI , where most of Konow's collection is deposited. Type locality: France , Amiens. Synonymy with E. brevicornis by Vikberg & Zinovjev (2006). Pontania pedunculi : Kopelke (1991) ; misidentification. Variability. Female: Body length: 3.2–4.6mm . Male: 2.8–4.8mm . Femora completely pale, to fuscous on anterior and posterior edges. Female and male: head usually yellow with large black ocellar patch extending to toruli, to nearly entirely black with only lateral vertex and upper orbits obscurely brown. Total number of specimens examined: 8. Genetic data. The short BOLD COI barcode sequence will not separate brevicornis from the other eleven North European species with closely similar barcodes ( acutifoliae , arcticornis , collactanea , etc.). Bionomics. Host plants: Salix cinerea (Vikberg & Zinovjev 2006) , S. cinerea × caprea ( Beneš 2015a ) , and rarely on S. aurita (Zinovjev 1999) . Biology: Kopelke (1991) , Vikberg & Zinovjev (2006). Distribution. Central and North Europe, north to S. Finland (Vikberg & Zinovjev 2006). Distribution in detail is unclear, because of taxonomic and nomenclatural confusion. E. brevicornis was reported from the British Isles by Liston et al. (2012), but these specimens have now been re-identified as E. pedunculi . Accordingly, E. brevicornis must be deleted from the faunal list of the British Isles. Occurrence in Sweden: published records; Skåne ( Benander 1966; the specimens identified as Pontania arcticornis are probably the morphologically very similar E. brevicornis , because the host of P. arcticornis does not occur at that locality ). Material examined: Härjedalen.
