Achrysis unicolor: Bischoff 1925: 306 .

Distribution. Denmark, Latvia, Sweden.—Transpalearctic: from West Europe to Mongolia ( Linsenmaier 1959).

Remarks. The species has been found from Denmark, Latvia and Sweden. It is very rare and has been classified as critically endangered in Sweden ( Cederberg et al. 2010). Recently it was recorded in southern Sweden for the first time in 50 years. Balthasar (1954) and Móczár (1967) reported the species from Finland, but these records are most likely erroneous, as Vikberg (1986a) noted. No Finnish specimens have been found from collections.
