Figure 52
Antenna: H. metallica ♂. Scale 1 mm.
Length 5–6 mm.
The female is entirely blue or blue-green with golden green reflections on the pronotum, mesoscutum and metasoma. The male is golden green with blue on the metanotum and propodeum. Both sexes resemble the male of H. fervida in colouration, but the punctation of the tergites is finer and sparser (Fig. 50), and the antennal segments are longer in the male (Fig. 52).
Distribution
Finland. Rare.
West Palearctic: only known from Finland and Russian Fennoscandia (Paukkunen et al. 2014).
