Taxonomy

Before 2020 Helicopsis lunulata was considered to be a synonym of Helicopsis striata and most of its populations were assigned to the latter species, though some large forms were treated as a separate species Helicopsis instabilis (Rossmässler, 1838).^[3]

Helicopsis cereoflava (Bielz, 1851) from Romania is probably a synonym of this species.^[3]
