Diagnosis (female). Antenna with solid clava ( Fig. 690 ); genal carina present; mesoscutellum with weak and indistinct submedian grooves, more distinct in posterior half ( Fig. 50 ), predominantly with isodiametric meshes; propodeum with posterior part of median carina split into a “Y”, and with anterior part raised into a tooth ( Fig. 50 ); hind coxa with a strong and complete carina along posterior margin ( Fig. 21 ); petiole short, conical and smooth; gaster 2.8× as long as wide, Gt 2 0.2× as long as Gt 4, Gt 1 with same strong reticulation as remaining tergites ( Fig. 50 ), medio-basal part of Gt

1 without transverse carina or edge dorsally.

Thoracic dorsum metallic greenish-blue. Legs with fore and hind coxae metallic greenish-blue, mid coxa black; trochanters dark brown; fore and mid femora dark brown with apex yellowish-brown, hind femur black with metallic tinges and apex yellowish-brown; tibiae yellowish-brown; T1–3 yellowish-brown, T4 dark brown. Petiole black.
