The Russian regional flora (https://www.plantarium.ru/page/view/item/689.html), Swedish Taxonomy Database (https://www.dyntaxa.se/Taxon/Info/8?changeRoot=True), and Flora of China (http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200007406), which together cover most of the range of the taxon, agree that Actaea erythrocarpa should be recognized at the full species level.
