Abstract Material from Fennoscandia currently identified as Incurvaria vetulella (Zetterstedt, 1839) appears to comprise two superficially very similar species: 1. vetulella and I. circulella (Zetterstedt, 1839), the latter having been regarded as conspecific with or a form of vetulella for the last century. Lectotypes of both species are designated, the two species are briefly redescribed, differences are discussed, and adults, male and female genitalia are illustrated. I. circulella is reported from northern Norway, Sweden, Finland and the USSR.
