Scape yellowish-brown, pedicel dark brown, flagellum black. Face below level of toruli black with golden tinges and clypeus black, frons metallic greenish-blue with scrobes black; vertex metallic greenish-blue. Mesoscutum with sidelobes black with metallic purple tinges, midlobe golden-green; mesoscutellum and propodeum golden-green. Legs with fore coxa brown, mid coxa yellowish-brown and hind coxa yellowish-brown at apex and along anterior part, dark brown along posterior part; trochanters yellowish-white; femora, tibiae and tarsi yellowish-white to yellowish-brown.
