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).
