( Fig. 2 )

Diagnosis. Head mostly yellowish-orange, legs yellowish, body dark brown and yellowish-testaceous; propodeum with an Y-shaped carina oriented backwards; nearly entirely smooth, except T1 longitudinally striate and some faint sculptures on face, tegula, and propodeum.

Description. COLOR. Head yellowish orange with brownish parts: flagellum, scape (laterally) and interocellar area; mesosoma dorsally dark brown, scutellum and lateral sides of pronotum yellowish, pleurae yellowishtestaceous; legs yellowish with tarsi infuscate; wing veins yellowish to dark brown, pterostigma testaceous, its anterior margin blackish; tergite 1 blackish brown, following tergites yellowish-orange and apically infuscate.

FEMALE (1 specimen). Body / fore wing / antenna / ovipositor sheath lengths (mm): 5.1 / 4.8 / 7.4 / 5.3.

Head. Entire head transverse and polished with a moderately dense pilosity, genae moderately long with temples regularly rounded behind eyes, 1.5x wider than high in facial view, 1.6x wider than long in dorsal view. Mandibles moderately long, basally slightly constricted then margins sub-parallel towards apex, teeth sub-equal, malar line 0.2x basal mandibular width. Subocular sulcus absent. Clypeus transverse, 2.0x wider than high, shallowly and sparsely punctate, its apical margin with a fine crenulated impression. Face transverse, 1.7x wider than high, sparsely and shallowly punctate. Occipital carina dorsally obsolescent, joining ventrally hypostomal carina distinctly before mandible basis. Antenna with 37 flagellomeres. Ocellar diameter 1.1x post-ocellar line and 0.4x ocullo-ocellar line.

Mesosoma. Entire thorax smooth and shining, except a deep transverse crenulated groove behind pronotal collar, some fine punctures below tegula and the complete, deep and finely crenulated notaulus. Scuto-scutellar groove shallow, with three weak cross carinae. Propodeum smooth with a median longitudinal carina, subdividing from basal fifth to apex into two sub-median parallel longitudinal carinae, the surface between them rugose. Legs elongate. Fore wing with first discal cell sessile (1Rs absent), M+Cu fully tubular and pigmented basally, 1cu-a distinctly apical to 1M, twice longer than 1Cu.
