Remarks. The presence of this species has been confirmed in all the Nordic and Baltic countries except Norway. Strand (1898: 97) reported the species from Norway, and later also Erlandsson (1971: 88), Soon (2004: 45), Artsdatabanken (2010) and Rosa & Soon (2012) mentioned it from the country. However, all Norwegian museum material under this name has turned out to belong to other species. In the latest Norwegian red list, the species was classified as data deficient ( Hansen et al. 2010). Only two old specimens are known from Denmark (see data above).

The name of this species has varied much in the literature. Dahlbom’s name ovata was in common use in the late 19th and 20th centuries, while in the early 20th century ovata was erroneously replaced by gloriosa and amoenula by many authors. The name gloriosa was later suppressed as a nomen dubium (ICZN 1998). Linsenmaier (1987, 1997) considered generosa as a subspecies of Holopyga fastuosa (Lucas, 1849) and synonymized ovata with generosa . According to an unpublished revision of European type material the name will once again change as another older name has been found for the taxon (Rosa, in prep.).
