The male and female are differently coloured. In the male, the head and mesosoma are completely green-blue and the metasoma is golden red (rarely greenish golden). In the female, the pronotum and mesoscutum are bright red (as in Fig. 53) or golden yellow, whereas the rest of the body has similar colouration as in the male. The pubescence is dark brown in both sexes. The species is easily confused with H. niemelai, but the mesotibial groove of the male is shallower and narrower, often indistinct (Fig. 57), and the female has a broader, apically undivided, tubercle on S3 (Fig. 59). Punctation of T3 is also sparser in both sexes, especially in the male (Fig. 62).
