Text in Brischke (1884: 170–171). Described : ♀ , ♂ , gall, larva, recorded hosts: Salix aurita , S. capraea [sic!]. Type material thought to have been destroyed, with most of the rest of Brischke's collection ( Blank & Taeger 1998 ) . Type locality: not stated, but probably East Prussia . Pontania bella : Konow (1901a) . Pontania ( Eupontania ) bella : Lacourt (1999) . ? Nematus baccarum Cameron, 1876d : 189 –190. Described: ♀ , gall, recorded host: Salix cf. aurita . Syntypes probably lost: not located in BMNH . Type locality: Scotland , near Dunkeld. Tentative synonymy with Pontania pedunculi sensu Kopelke [= E. brevicornis ] by Kopelke (1991) , or with E. pedunculi by Vikberg & Zinovjev (2006). Nematus curticornis Cameron, 1885 : 202 . Described: ♀ . Syntypes not located in BMNH . Type locality: Scotland , Rannoch. Pontania curticornis : Konow (1890) . Pontania bella var. nigrescens Enslin, 1915 : 360 . Described: ♀. Syntypes, ♀, ZSM [not examined]. Type locality: not stated. Synonymy with P. pedunculi by Taeger et al. (2010) . Pontania pusilla Lindqvist, 1964 : 122 –124. Described: ♀ , ♂ . Holotype , ♀ , FMNH [examined]. Type locality: Finland , Sundholmen Island (now part of Helsinki ). Synonymy with P. pedunculi by Vikberg (1970) , confirmed by Vikberg & Zinovjev (2006). Pontania gallarum : Kopelke 1991 : 89 ; misidentification. Notes on types and taxonomy. P. pusilla . Also examined: paratype ["Allotype"], 1♂, FMNH. Variability. Female: Body length: 2.5–4.3mm . Supraclypeal area, upper outer and inner orbits pale, to black. Male: 2.8–3.7mm . Female and male: femora usually entirely pale, but may be extensively fuscous in northern specimens. Total number of specimens examined: 17. Genetic data. In BOLD COI barcoding, nearest neighbours are viminalis , and at a different position but also differing by about 1.9%, the nearly undifferentiated aggregation of numerous viminalis subgroup taxa that includes, for example saliciscinereae and nivalis . Thus, the short BOLD sequence for pedunculi appears to be sufficiently distinctive to identify this species. However, only the first sample under the name pedunculi in Fig. 1 ( E. pedunculi / S. caprea , next to E. viminalis ) apparently has this haplotype. The other three samples included in Fig. 1 under the name pedunculi are problematic, and were possibly misidentified. Bionomics. Host plants: Salix aurita , S. caprea , S. starkeana starkeana , S. starkeana cinerascens (Vikberg & Zinovjev 2006) , S. silesiaca ( Beneš 2015a ) , S. caprea × phylicifolia ( Hjältén et al. 2000 ) . Biology: Hartley (1998) , Kokkonen (2000) , Vikberg & Zinovjev (2006). Distribution. Through most of Europe north to Inari Lapland in Finland , and East to Yakutia, Magadan and Sakhalin (Vikberg & Zinovjev 2006). Occurrence in Sweden : published records; probably throughout Sweden ( Coulianos & Holmåsen 1991 ) north to Luleå Lappmark (Jokkmokk; Julin 1936 ). Material examined: Skåne , Västerbotten , Luleå Lappmark (Gällivare).
