Distribution. Denmark, Estonia, Finland, Latvia, Lithuania, Norway, Sweden, Russian Fennoscandia.—Transpalearctic: from West Europe to Mongolia ( Linsenmaier 1997).

Remarks. The species is known from all the Nordic and Baltic countries, but it is usually uncommon and found in low numbers. The northernmost records are from northern Sweden. In Finland it has declined and has been classified as near threatened ( Paukkunen 2010). Soon (2004: 46) reported C. pseudobrevitarsis from Norway and Denmark, but later the record from Norway proved to be erroneous. However, one specimen was recently found from southern Norway (Farsund) and the determination was confirmed by DNA barcoding. Records from Denmark are based on two specimens in ZMUC, which were collected from Bornholm and Zealand (see data above).

According to mitochondrial DNA studies, the species is divided into two genetically distinct lineages, both of which have been found from the Nordic and Baltic countries ( Soon et al. 2014). The other lineage is closer to C. brevitarsis , making C. pseudobrevitarsis paraphyletic, and therefore the lineages could represent different species. The morphological differences and nomenclature of these two lineages remain to be determined.
