Diagnosis. Inner margin of eyes parallel near clypeus; supraclypeal area subquadrate, width 1.08× its height; antenna with 39–42 flagellomeres; juxtacoxal carina complete with perpendicular carinae absent or vestigial; median longitudinal carina of propodeum faint and incomplete, not reaching postscutellum; body black except for palpi, fore, mid legs and ovipositor.

Description. Female ( Fig. 8H ): Fore wing 5.1–6 mm.

Head. Densely punctate and covered with setae; lateral height of head 0.81–0.83× the size of mesopleuron; mandibles short and stout, apex 0.78–0.88× as wide as base, upper tooth broader than the lower tooth; malar space 0.57–0.65× as long as basal width of mandible; inner margin of eyes parallel near clypeus; supraclypeal area subquadrate ( Fig. 8A ); width 1.08–1.11× its height; lateral ocellus separated from eye by 0.37–0.4× its own diameter; interocellar distance 0.68–0.72× the diameter of lateral ocelli; interocellar area with sparse small setae; antenna with 39–42 flagellomeres; width of first flagellomere 3.9–4.4× its height; height of second flagellomere 0.49–0.55× height of first flagellomere; last flagellomere cone shaped with a rounded apex, occipital area slightly imbricate.

Mesosoma . Pronotum reticulate, ventrolaterally with transverse wrinkles; epomia present reaching the base of mesoscutum; mesoscutum punctate; scutellum and post scutellum densely covered with setae; mesopleuron dorsolaterally reticulate with weak incomplete wrinkles and covered with setae; speculum denudate with weak wrinkles ( Fig. 8C ); epicnemial carina present, reaching only basal part of mesopleuron; mesopleuron ventrally foveolate without wrinkles and covered with setae; sternaulus absent; posterior transverse carina of mesosternum forming two teeth produced near the coxal area; metapleuron punctate and covered with setae with its posterior part densely covered with setae; juxtacoxal carina complete with perpendicular carinae absent or vestigial; juxtacoxal area reticulate; pleural carina complete; spiracle elliptical with its width 0.3–0.38× the spiracle height; propodeum hairy and reticulose; petiolar area, areola and basal area reticulate without wrinkles; lateral longitudinal carina of propodeum incomplete starting from the propodeum neck and ending on the posterior transverse carina of propodeum; median longitudinal carina of propodeum incomplete, not reaching postscutellum and weak on its basal area ( Fig. 8B ); propodeum neck 0.71–0.75× the size of hind coxa.

Legs. Height of fore t1 0.7–0.71× height of fore t2–t5; mid coxae with several wrinkles on dorsal view; height of mid t1 0.82–0.84× height of mid t2–t5; height of hind legs with t1 0.84–0.86× height of hind t2–t5.

Wings. Hyaline and covered with small setae; fore wing: vein 1cu-a arising after of 1M+Rs; vein 3/Cu placed at midlenght of 2/Cu and crossvein 2cu-a; vein 1/Rs+M curved; bulla of 1/Rs+M placed after its midlength near 2/M; 2/RS small 0.63–1.7× the size of 2/M; bulla of 2m-cu placed near 2/M by 0.17–0.4× its distance of 4/cu; hind wing: vein 1-Rs forming a curve with 1r-m angle; hind wing with 5 hamuli.

Metasoma. Tergites imbricate; first tergite with sparse hair, first sternite glabrous with subpetiolar process inconspicuous ( Fig. 8D ); tergite II 0.74–0.85× the length of tergite I; remaining tergites and sternites punctate covered with small setae; thyridium elliptical almost rounded rectangular ( Fig. 8E ); ovipositor sheath covered with long setae; ovipositor straight with 1.22–1.44mm long; ovipositor notch not deep ( Fig. 8G ), distant from apex 0.29–0.4× length of ovipositor; ovipositor notch angle 102–110º; ovipositor ventral valve without a lobe near apex.

Color. Pubescence golden. Head black palpi pale-yellow; mandibles black with mandible flange yellowish black; ocelli reddish brown; antenna black; scape black with a thin brown line on its apex; pedicel black. Mesosoma : black; fore leg with black coxae; pale-yellow between trochanter and t4; t5 black; mid leg with black coxae, trochanter and trochantellus pale-yellow; femur pale-yellow with ventral black mark, tibia pale-yellow with sparse black setae and a transverse row of black setae near its apex; t1 pale-yellow, t2 to t4 pale brown with black marks; t5 entirely black; hind legs entirely black between coxae to half of t1; lower half of t1 to t4 pale-yellow; t5 black. Metasoma: entirely black except for yellowish inferior edges of the tergites and reddish-brown ovipositor ( Fig. 8F ).

Male: unknown.

Biology: Host unknown.

Comments: This species is readily distinguished from other Brazilian species by the body coloration (mostly black) and by the faint and incomplete median longitudinal carina of propodeum, not reaching the postscutellum (which was not found in any other species from Brazil).

Etymology: This species is named in honor of Maria Stela Marrelli Caldas Leite Lucas, first author’s significant other.
