Description, Female ( Fig. 2 ): body length 2.9–3.6 mm.

Color. Head dark brown, clypeus varies from all brown yellowish to brown yellowish with apical margin yellow ( Figs 3–4 ), mandible yellow, palpi light yellow, antenna with scape and pedicel brown yellowish, flagellomeres brown. Legs mostly yellow, apex of hind tibia, femur and all tarsomeres light brown. Pronotum yellow anteriorly and brownish posteriorly, mesosoma dark brown ( Fig. 5 ). Propodeum black. Metasomal tergite 1 black with apical margin white, tergite 2 light brown with apical margin white, remaining tergites light brown ( Fig. 6 ), sternites and ovipositor sheaths light brown. Tegula white, wings hyaline.

Head. Antenna with 19 flagellomeres with setae shorter than flagellomere width; first flagellomere length 3.0– 4.2× width, second flagellomere length 3.0–3.5x width. Face polished with sparse setae, width 1.5–1.94× height, malar space 1.3–1.6× basal width of mandible, mandible with two teeth, not twisted. Clypeus convex, pilose, truncate, punctate and with long setae, width 1.1–1.7× height ( Figs 3–4 ). Eye-ocellar distance 0.98–1.2× greatest diameter of lateral ocellus.

Mesosoma. Pronotum smooth with epomia. Mesopleuron smooth, with epicnemial carina extending to the middle of the mesopleuron, sternaulus present only anteriorly, mesopleural fovea punctiforme, mesopleural groove deep and smooth, posterior transverse carina of mesosternum present ( Fig. 7 ). Mesoscutum and scutellum smooth and polished with sparse setae, notaulus absent, prescutellar groove smooth without carinae. Propodeum polished with lateral long and sparse setae, pleural carina complete, posterior transverse carinae complete and the lateral longitudinal carinae present only at the apex ( Fig. 8 ).

Metasoma. Tergite 1 with two median longitudinal carinae converging at apex, smooth with posterior margin striate or rugose, length 1.7–1.9× apical width ( Fig. 9–10 ). Tergites 2 – 7 smooth. Ovipositor short, 0.33× length of hind tibia.

Wings. Fore wing length 2.6–3.2 mm, hind wing length 2.0– 2.4 mm. Portion of cubitus between intercubitus and second recurrent vein 0.87× of second recurrent vein; section dg of radiella in hind wing 0.44× of length section gh; nervellus slightly reclivous to base.

Male. Unknown

Comments. This species can be readily separated from other species by the first tergite being mostly smooth, black with the apex white, metasomal tergite 2 light brown with apical margin white and the remaining tergites light brown.

Distribution: Brazil, Itamonte, MG ( Fig.1 ).

Etymology: The name refers to the abundance of specimens collected.
