The female and the male are entirely differently coloured. The female is mainly shiny red-purple, but the legs, mesopleuron, metanotum, propodeum, lower part of head and lateral corners of pronotum are blue. The male is entirely green or blue-green, sometimes with golden reflections or a completely golden metasoma. The colouration of the male is similar to H. metallica, but the punctation of the tergites is denser and coarser (Fig. 49) and the antennal segments are shorter (Fig. 51).
