Abstract: 286 Euura erecta (Lindqvist, 1945) Figs 300, 526–527 Amauronematus erectus Lindqvist, 1945: 107–108. Syntypes ♀ ♂ (MZH?), not located. Type localities: Finland, Lapland; Sweden, Virihaure; Russia, Dudinka. Diagnosis Females are most similar to E. malaisei, which also has a rather long valvula 3 (tends to be shorter in other species of viduata group). The lancet is less curved in E. erecta than in E. malaisei. Penis valves are most similar to E. malaisei, E. leucolena and E. rectiserra, but in some specimens (DEIGISHym12074, 210009_LGB) of E. erecta the apex of pseudoceps forms a small filament. The other males we have checked (DEI-GISHym12062, DEI-GISHym84015) lack the filament at the apex of pseudoceps and are genetically somewhat different. Nevertheless, the genetic variability is large as indicated by heterozygous females. The females, which we have identified based on morphology, seem to cover the genetic variability between the males. The specimens 210008_SSR and 210009_LGB were caught in copula on Salix lanata. Host plants Salix lanata. Macek et al. (2020) reported Salix aurita, but this is probably based on a misidentification of the sawfly. For example, the penis valve shown for E. erecta by Macek et al. (2020) belongs to the E. bipartita group (perhaps E. connecta). Genetics COI Based on 21 specimens, maximum within-species distance is 3.5% and the nearest neighbour, diverging by a minimum of 0.15%, is Euura leucolena. Nuclear Based on 21 specimens, maximum within-species distance is 1.08% (1.01% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.09%, is Euura leucolena (ZMUO.041208). Distribution and material examined Palaearctic. Specimens studied are from Finland, Norway, and Sweden.
