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 : 208

279 Euura vicina group

Mostly defined based on genetic data. The species are also morphologically similar, but we have not found consistent morphological characters that define the group to the exclusion of other Euura . Host plants are known for E. vicina ( Rumex ) and E. notabilis ( Bistorta , this study). In addition, based on the sequencing of larval gut contents, a specimen (DEI-GISHym80076) from Primorsky Krai ( Russia) had apparently fed on Bistorta sp. At this point it is not possible to say which species DEI-GISHym80076 could be, genetically it is closest to E. putoni and E. notabilis , but currently there is no genetic data for E. nigerrima . Based on these host plant observations and the habitats where other species have been collected, it can be suggested that all species of the vicina group are on Polygonaceae .
