Chrysis pseudobrevitarsis : Linsenmaier 1959: 158.

Diagnosis.

Length 6-10 mm. The colouration and habitus are similar to Chrysis brevitarsis , but the mandible does not have a subapical tooth, the punctation of the mesoscutum is laterally denser and the punctation of T2 is usually coarser. The short metatarsus (Fig. 169) is characteristic for the females of both species. Males can be confused with e.g. Chrysis longula and Chrysis impressa , but the spurs of the mesotibia are approximately equal in length (Fig. 169), the shape of the body is more compact, and the inner margin of the paramere is angled (as in Fig. 137), not rounded.

Distribution.

Denmark, Estonia, Finland, Latvia, Lithuania, Norway, Sweden. Relatively rare. - Trans-Palearctic: from western Europe to Mongolia ( Linsenmaier 1997).

Biology.

Habitat: forest margins, clearings and gardens with sun-exposed dead wood. Adults occasionally visit flowers of Apiaceae ( Petit 1987). Flight period: late May to late August. Host: primarily Euodynerus notatus (Jurine) ( Pärn et al. 2014, our own obs.), but probably also Euodynerus quadrifasciatus (Fabricius) and Ancistrocerus antilope (Panzer) ( Vespidae ) ( Heinrich 1964, Morgan 1984, Martynova and Fateryga 2015).
