Length 5–7 mm.
Both sexes have similar colouration: the head, propleuron, mesopleuron, propodeum and legs are blue or blue-violet, whereas the pronotum, mesoscutum, mesoscutellum and metascutellum are red. The colouration is relatively similar to the female of H. fervida, but the head is completely blue (without red vertex), the metascutellum is red (not blue) and the mesoscutellum is uniformly punctured (not sparser anteriorly).
