Length 6–9 mm.
The body is entirely dark blue or violet with greenish reflections. Usually the male is more greenish or lighter blue than the female. The species can be confused with C. iris, but the mesoscutum is medially distinctly darker than laterally (Fig. 156), the punctation of the mesoscutum is denser and the ovipositor is broader (as in Fig. 91). Also the black spots of S2 are smaller and the apical teeth of T3 are more sharply produced (Fig. 82).
Sweden. Very rare. Only one specimen is known from Östergötland, collected probably in the late 1840s or early 1850s (leg. A.G. Dahlbom).
West Palearctic: central and southern Europe, northern Africa, Asia Minor (Linsenmaier 1959).
