description
Euura pedunculi: Prous et al. (2014).
description
Variability. Female: Body length: 2.5 – 4.3 mm. Supraclypeal area, upper outer and inner orbits pale, to black. Male: 2.8 – 3.7 mm. 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 2015 a), S. caprea × phylicifolia (Hjältén et al. 2000). Biology: Hartley (1998), Kokkonen (2000), Vikberg & Zinovjev (2006).
distribution
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).
