Pronotum shiny, unsculptured, not crossed by transverse impression or very slightly impressed. Metanotum very sloping anteriorly, about coplanar to mesoscutellum. Metapectal-propodeal disc shiny, unsculptured; propodeal declivity transversely striate. Metapectal-propodeal disc usually unsculptured, occasionally granulate. Meso-metapleural suture obsolete. Protarsomeres in following proportions: 10:2:4:9:15. Enlarged claw ( Fig. 201A ) with one small subapical tooth and a two peg-like setae + one bristle.
