Prous, Marko, Liston, Andrew, Monckton, Spencer K., Kramp, Katja, Vårdal, Hege, Vikberg, Veli, Heibo, Erik & Mutanen, Marko, 2025, West Palaearctic species of Euura Newman, 1837 (Hymenoptera, Tenthredinidae), European Journal of Taxonomy 977, pp. 1-377 : 115

166 Euura gregaria group

The group is defined based on its characteristic claw shape (the part between the apical and subapical tooth forming a semicircle) and genetic data. We do not recognize the European and Nearctic species as separate (see below under Euura gregaria ). Euura evenensis ( Zhelochovtsev, 1981) from Magadan oblast may belong to this group ( Zhelochovtsev & Zinovjev 1981), but this requires confirmation. Euura evenensis was described based only on males and it does not seem to be conspecific with E. gregaria (males 3.0– 4.5 mm) as it is larger (5–7 mm).
