Gnorimoschema diffluellum; Scrobipalpula cacuminum (Frey, 1870) is technically a synonym of diffluella, but has often been confused with Scrobipalpa murinella (see Huemer & Karsholt, 2010a).
Gnorimoschema uniflorellum, attributed by Hering (1957a) to Klimesch, and associated by him with Erigeron and Homogyna has never been published; the name is not available for nomenclature, being based on “the work of an animal”. It is considered to mean diffluella by Huemer & Karsholt (2010a).
