Occipital carina fading out before reaching the hypostomal carina. Gena smooth, shiny and glabrous.

Mesosoma . Pronotum shiny, impunctate, moderately pilose, ventrally with weak wrinkles, epomia weak, complete, short, ending far from dorsal margin of pronotum, after diverging from pronotal collar, approximately straight. Mesoscutum 1.21 × as long as wide, scarcely pilose, shiny, scarcely punctate; notaulus reaching about 0.72 of mesoscutum length, moderately impressed, surface over of notaulus not wrinkled.

Mesosternum moderately punctate, without wrinkles. Transverse sulcus at base of propodeum very wide, about 0.76 × as long as anterior area of propodeum, smooth; metapleuron impunctate, with transverse wrinkles, sparsely pilose; juxtacoxal carina absent. Fore tibia distinctly swollen. Mesal lobe of t4 with a distinct cluster of stout bristles. Hind coxa finely punctate and pilose.

Propodeum. 1.19× as long as wide, shiny, moderately pilose; anterior area smooth; spiracle elliptic, SWL 1.73; anterior transverse carina present. Propodeal wrinkles strong, complete, anteriorly very close, centrally and posteriorly spaced; posterior transverse carina absent.

Wings. Fore wing vein 1-Rs+M distinctly sinuous, with bulla placed around its midlength; crossvein 1m-cu more curved; 1M+Rs anteriorly straight, posteriorly weakly curved; vein 2Cua 0.58× as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed on midlength; cell 1+2Rs (areolet) small, APH 0.34 pentagonal, about as high as wide, AWH 0.99; crossvein 3r-m absent; vein 3-M longer than 2-M; 4-Rs straight; 4-M straight, apically slightly curved. Hind wing with vein 1-M forming a straight angle with vein Cua; vein 2-Rs straight; HW1C 1.31; vein Cub distinctly convex on posterior half, forming a distinctly obtuse angle with vein Cua; vein 2-1A close but not reaching posterior wing margin.

Metasoma. First tergite long, about 0.92 × as long T2, finely punctate, sparsely pilose; T1LW 2.8; T1WW 1.22; T1 spiracle at middle; ventro lateral carina absent; thyridium longer than wide; T2–T8 minutely coriacious, punctate, uniformly pilose; T2LW 1.58; T2WW 2.07; OST 1.49; ovipositor slender, basally cylindric, apically slightly depressed; dorsal valve without ridges.

Color. Head, black and whitish, meso and metasoma whitish, black and bright orange. Head: white; mandible apex, supra-antennal area and orbital band, black; scape ventrally orange; flagellum dark brown and f10-15 whitish, f16 with small white spot laterally. Mesosoma : mostly white; mesoscutum, except for the margins, subcircular spot, scutellar carina, scutellum, tegula, subalar ridge, dorsal region of epicnemial carina, bright orange; notaulus dark brown ( Fig. 4 ); large spot on pronotum, dorsal half margin of mesopleuron, epicnemial carina, mesosternum, mesepimeron (mesopleural suture) and hypoepimeron, a half of posterior area of propodeum, almost entire dark brown to blackish; the another part of propodeum, posteriorly with whitish U-shaped mark; anterior area of propodeum with two lateral pale yellow marks ( Fig. 5 ); fore and mid legs mostly whitish; first and mid trochanter dorsally and laterally brown, second fore and mid trochanters with ventral and dorsal brown spot; first and mid femora with dorsal brown stripe; fore tibia dorsally orange, mid tibia dorsally with dark brown stripe; fore and mid tarsi dark brown; hind coxa with dorsal and lateral blackish marks, hind trochanter marked with dark brown, orange and whitish; hind femur mostly orange, except base and apex infuscated; hind tibia mostly black except for the base white; hind trochanter black only at the apex; hind tarsomeres white, base of first tarsomere black. Metasoma: dark brown and whitish. Anterior and posterior area of T1, whitish, median dark brown; T2–4 dark brown at the anterior area and posteriorly whitish; T5–6 predominantly brownish, only with its white lateral borders; T7 predominantly whitish, anteriorly with a small white stripe; T-8 brownish, whitish at the apical margin; S1–8 whitish with brown marks laterally.

Male. Unknown.

Distribution. Angra dos Reis, RJ, Brazil.

Host. Unknown.

Etymology. Named in honor of a dear friend and entomologist co-worker: Suzan Beatriz Zambon da Cunha.

Comments. Mostly closer to M.variegatus Szépligeti, 1916 from which it can be differentiated by: MLW 1.47 (vs. MLW 2.06); CHW 3.86 (vs. CHW 2.24); CWW 1.62 (vs. 3.25); antenna with 23 flagellomeres (vs. 25 flagellomeres); apex of apical flagellomere not distinctly tapered (vs. distinctly tapered); supra-antennal area striate near antennal sockets (vs. without median line); pronotum moderately pilose (vs. glabrous); mesoscutum scarcely pilose (vs. densely and sparsely pilose); scuto-scutellar groove shallow, without wrinkles (vs. moderately deep, with vestigial longitudinal wrinkles); subalar ridge weakly projected (vs. moderately projected); sternaulus very weakly, almost indistinct (vs. sternaulus moderately strong); scrobe shallow (vs. scrobe moderately deep); mesopleural suture without wrinkles (vs. mesopleural suture ventrally with weak longitudinal wrinkles, wrinkles dorsally vestigial); mesosternum moderately punctate, without wrinkles (vs. mesosternum medially with short transverse wrinkles); metapleuron impunctate, sparsely pilose (vs. metapleuron moderately punctate, densely pilose); juxtacoxal carina absent (vs. represented by very short ridges); fore tibia distinctly swollen (vs. fore tibia weakly swollen); spiracle elliptic, SWL 1.73 (vs. spiracle elongate, SWL 4.57); bulla of crossvein 2m-cu placed on midlength (vs. bulla of crossvein 2m-cu placed mostly on posterior half); 4-Rs straight (vs. 4-Rs distinctly sinuous); OST 1.49 (vs. OST 0.98). In relation to colors can be distinguished mainly by: mesosoma mostly black, whitish and bright orange (vs. mesosoma black); central whitish mark on mesopleuron connected to whitish mark at subalar ridge (vs. not connected); propodeum posteriorly with whitish U-shaped mark (vs. posterior subcircular mark on propodeum); anterior area of propodeum with two lateral marks pale yellow (vs. anterior area without marks).
