Mesosoma . Pronotum dorsolaterally imbricate, laterally and ventrolaterally polished with transverse wrinkles; epomia present almost reaching the base of mesoscutum; mesoscutum finely punctate; scutellum and post scutellum densely covered with setae; mesopleuron dorsolaterally foveolate with strong transverse wrinkles and covered with sparse setae ( Fig. 10C View FIGURE 10 ); speculum denudate with transverse wrinkles; epicnemial carina present, reaching only mid part of mesopleuron; mesopleuron ventrally foveolate without wrinkles and sparse setae; sternaulus absent; posterior transverse carina of mesosternum straight not produced near the coxal area; metapleuron punctate and with its posterior part densely covered with setae; juxtacoxal carina complete and strong impressed with perpendicular carinae vestigial; juxtacoxal area imbricate; pleural carina complete; spiracle elliptical with its width 0.44–0.62× the spiracle height; propodeum hairy and foveolate; strong transverse wrinkles on petiolar area ( Fig. 10B View FIGURE 10 ); areola and basal area with vestigial wrinkles; lateral longitudinal carina of propodeum incomplete not reaching propodeum neck; median longitudinal carina of propodeum complete; propodeum neck 0.78–0.83× the size of hind coxa.

Legs. Height of fore t1 0.71–0.81× height of fore t2–t5; height of mid t1 0.85–1.01× height of mid t2–t5; height of hind t1 0.85–0.91× 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 2 / Cu 0.81–1× the size of 2cu-a; vein 1 / Rs+M curved; bulla of 1 / Rs+M placed after its midlength near 2 / M; 2 / RS 0.69–0.9 as long as 2 / M; bulla of 2 m-cu placed near 2 / M 0.2–0.4× the distance between the bulla and 4 / Cu vein; hind wing: vein 1-Rs forming a curve with 1r-m angle; hind wing with 5 hamuli.

Metasoma. Tergites imbricate; first tergite with sparse setae, first sternite glabrous with subpetiolar process conspicuous; tergite II 0.75–0.83× the length of tergite I; remaining tergites and sternites finely punctate covered with small setae; thyridium elliptical almost rounded rectangular ( Fig. 10E View FIGURE 10 ); ovipositor sheath covered with long setae; ovipositor straight with 0.96–1.1mm long; ovipositor notch not deep, distant from apex 0.16–0.24× length of ovipositor; ovipositor notch angle 95º–120º; ovipositor ventral valve with a lobe near apex ( Fig. 10G View FIGURE 10 ).

Color. Pubescence silvery. Head: black; palpi pale-yellow; mandibles dark-yellow with brown teeth; ocelli brown; antenna dark brown, scape dark brown with a thin pale-yellow line on its apex; pedicel dark brown. Mesosoma : black; tegula dark brown; fore leg pale-yellow with t5 brown; mid leg with black coxae, trochanter and trochantellus pale-yellow, femur with edges pale-yellow and brown in mid part, tibia to t4 pale-yellow, t5 brown; hind leg mostly black with dark yellow trochantellus. Metasoma: first segment with anterior part black, mid part dark brown and postpetiole black ( Fig. 10D View FIGURE 10 ); tergite II dark brown; thyridium pale brown; sternite II light brown with its extremities pale brown ( Fig. 10E View FIGURE 10 ); remaining tergites dorsally black and ventrally orange brown; remaining sternites pale-yellow with dark brown marks; ovipositor sheaths and cerci black, ovipositor orange brown.

Male ( Fig.11A View FIGURE 11 ): Very similar to female, except by the lateral height of head 0.86–0.89× the size of mesopleuron; mandibular apex 0.72–1× as wide as base; malar space 0.29–0.37× as long as basal width of mandible; width of supraclypeal area 1.16–1.25× its height; spiracle width 0.5–0.62× the spiracle height; propodeum neck 0.63–0.86× the size of hind coxae; fore leg with height of t1 0.72–0.78× height of fore t2–t5, mid legs with height of t1 0.8–0.9× height of mid t2–t5 and hind legs with height of t1 0.74–0.91× height of mid t2–t5; length of tergite II 0.75–0.82× length of tergite I; 2/RS 0.5–0.77× the size of 2/M; hind legs with t2–t4 or t3–t4 pale-yellow; metasomal tergites I–II and V–VIII darker than female; gonoforceps and cercus also black.

Biology: Host unknown.

Comments: Very similar to Charops angelicae sp. nov. from which it can be differentiated by the dark brown scape, with a thin pale-yellow line on its apex; dark brown pedicel (vs the bicolored scape and pedicel, anteriorly yellow and posteriorly brown) and width of supraclypeal area 1.20–1.37× its height (vs width of supraclypeal area 1.11–1.18× its height).

Etymology: This species is named in honor of Maria Tereza Guarnieri Doria first author’s grandmother.
