Remarks. The species is known from Denmark, Estonia and Sweden. It has also been reported from Norway by Trautmann (1927: 36, as Omalus truncatus), Benno 1950: 27 (as Omalus truncatus), Balthasar (1954: 89, as Omalus truncatus), Erlandsson (1971: 88, as Chrysellampus truncatus), Soon (2004: 45) and Artsdatabanken 2010. However, the record from Norway is based on an old, unlabeled specimen, which might not have been collected from Norway (Artsdatabanken 2010). In Sweden most records are old and the species has been classified as data deficient in the Swedish red list (Cederberg et al. 2010, Cederberg 2012). Only one recent record is known from the country (Sm: Bergkvara 14–21.VII.1996, by yellow pan trap, leg. Roy Danielsson). In Denmark only old records are known.
