Diagnosis.

Length 4-7 mm. The species differs from Elampus panzeri and Elampus foveatus by the structure of the apical truncation of T3, which has pointed margins ventrally and resem bles a sickle or a boomerang in shape (Fig. 45). Sometimes the apical truncation is very narrow, similar to that of Philoctetes truncatus . The lateral margins of T3 are shallowly concave anterior to the apical truncation. As opposed to Elampus panzeri and Elampus foveatus, the scrobal carina reaches the angle of the omaulus (Fig. 42). Both sexes are usually bicoloured with a blue or greenish head and mesosoma, and a reddish metasoma. Entirely greenish or blue specimens are found occasionally.

Distribution.

Denmark, Estonia, Finland, Norway, Sweden. Relatively rare. - Trans-Palearctic: widely distributed in the Palearctic Region, from Europe to China (Rosa et al. 2014).

Biology.

Habitat: sparsely vegetated sandy areas, heaths. Adults occasionally visit flowers of Apiaceae and Rosaceae (Linsenmaier 1997, Rosa 2004). Flight period: May to July. Host: Mimesa bicolor (Jurine), Mimesa equestris (Fabricius) and Mimesa lutaria (Fabricius) ( Crabronidae) (Benno 1950, Lomholdt 1975).
