Distribution. Denmark, Estonia, Finland, Latvia, Lithuania, Norway, Sweden, *Russian Fennoscandia.—Transpalearctic: from West Europe to central Asia and Siberia (Linsenmaier 1959, 1997).
Remarks. The species is widespread, but scarce in the Nordic and Baltic countries. The northernmost records are from northern Finland (Lkoc: Kittilä) and Sweden (Lu. Lpm: Gällivare). In Finland, C. longula seems to have declined and it has been classified as near threatened (Paukkunen 2010). Soon (2004) reported the species from Denmark based on 18 Danish specimens in ZMUC (det. E. Valkeila).
One female specimen from Sb: Kuopio, Finland was selected by W. Linsenmaier as a paratype (“cotype”) of Chrysis longula aeneopaca Linsenmaier, 1959. According to Linsenmaier (1959) aeneopaca is an eastern subspecies of C. longula, the distribution of which covers Fennoscandia (Finland), Siberia, Transcaspia, China and Japan. Morphologically it is similar to the nominotypical form, but the tergites are basally darker brown, and the basal part of the second tergite has finer and denser punctation. In this respect it resembles C. subcoriacea. In fact, E. Valkeila and Vikberg (1986b) considered it erroneously as a synonym of C. subcoriacea. Analysis of mitochondrial DNA has shown that genetic divergence between C. l. aeneopaca and C. l. longula is very low, suggesting that they probably are conspecific (Soon et al., 2014). No other specimens of Chrysis l. aeneopaca are known from Finland apart from the paratype, and it is possible that the paratype is mislabeled or was accidentally imported into the country.
Linsenmaier (1951) also described Chrysis ignita var. sublongula, which he later classified as a subspecies of C. longula (Linsenmaier 1959). The distribution area of sublongula consists of Europe and Japan (Linsenmaier 1959, Rosa 2006). Morphologically sublongula resembles the nominotypical subspecies, but is smaller sized. According to unpublished studies of mitochondrial DNA, northern European samples of sublongula and longula most likely belong to the same species, as they do not differ genetically from each other (Soon et al. 2014). Because the distribution area of sublongula is sympatric with the nominotypical subspecies, it should not be considered as a separate subspecies, but at most as a form (f.) of C. longula. Several small specimens of C. longula, determined as sublongula by Linsenmaier, can be found from Nordic collections.
