Abstract

Diagnosis : So far as the type species is concerned, the subgenus is recognizable by the robust and rather small size, the entire process of the labrum, the shiny integument, and the presence of very fine and dense punctures on the metasoma which is black and red. The female of this species is further distinct in having the propodeal corbicula not well developed, with dorsal fringe of rather scanty, not well arranged hairs, interior of corbicula with sparse, fine, simple hairs throughout, the trochanteral floccus perfect and dense, the tibia1 scopa compact with simple hairs, and the posterior spur of the hind tibia slightly widened and curved near the base. The male of this species is characterized by the yellow clypeus, and primarily by the aedeagus of the genitalia which is keeled medially.
