T2LW 1.22; T2WW 2.02; thyridium about as long as wide, without small circular depression just behind it; T2–8 covered with small, shallow foveae, densely and uniformly pilose. OST 1.41; ovipositor moderately stout, straight, basally cylindric, apically slightly depressed; dorsal valve with four weak ridges; ventral valve apex with 7 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth rugulose.

Color. Head and mesosoma black with light yellow marks, metasoma bright orange. Head: black; clypeus except borders, mouthparts, supraclypeal except somewhat H-shaped mark and orbital band shortly interrupted at dorsal margin of eye, light yellow (223,213,139); mandible centrally and flagellum, dark brown; f6–10 entirely white, f5 and f11–12 partially white. Mesosoma: black; collar connected with anterior 0.4 of dorsal margin of pronotum, lateral margin of propleuron, subcircular spot and lateral horizontal dash at mesoscutum, small spots over notaulus, scutellar carina, scutellum, tegula, central mark reaching ventral margin of mesopleuron, dorsal division of metapleuron, apical 0.25 of metapleuron and lateral marks covering 0.4 of propodeum, light yellow; anterior face of fore and mid coxa, coxa, light yellow; fore and mid femora, all tibiae and tarsi bright yellow lighter towards apex, except dorsal stripes on basal 0.7 of fore and mid femora and all t5, blackish; hind coxa bright orange (216,108,045), basally dark brown, with posterior yellow spot; hind trochanters and femur bright orange. Metasoma: bright orange, with sparse fuscous marks.

Male. Fore wing 4.95–6.02 mm long. Generally similar to female, except for the following: clypeus, mandible except apex and supra-antennal area, light yellow; scape ventrally with yellowish spot; orbital band wide at gena; antenna with 20–23 flagellomeres; pronotal wrinkles weak or almost indistinct; ventral 0.5 of mesopleuron light yellow, except small area over sternaulus at anterior 0.2–1.0; mesosternum light yellow except central posterior mark; fore and mid legs without dark marks except brownish dorsal stripes on femora; hind coxa basally dark brown, apically light yellow; basal 0.3 of hind tibia, apical 0.5 of t1 and t2–4, whitish; apical 0.7 of femur, basal 0.5 of t1 and t5, blackish; median depression on T1 weak; T1–2 almost always anteriorly marked with blackish.

Variation. Fore wing 8.03–9.64 mm long. Supra-clypeal area sometimes almost entirely black; antenna with 21–24 flagellomeres; lateral yellow marks on propodeum sometimes connected apically; median depression on T1 weak to strong. Several specimens with light yellow marks at mesosoma variously reduced; central mark on mesopleuron covering 0.05–0.4 of its surface, sometimes divided into two separate marks; specimens most extensively black have only the following yellow areas: collar, subcircular spot on mesoscutum, tegula, scutellum, small mark at ventral margin of mesopleuron, dorsal division of metapleuron and lateral marks covering 0.25 of propodeum. A few specimens with dorsal margin of pronotum completely yellow, metasoma almost entirely yellow and T1 with posterior yellow stripe. Dark area on legs also often more extensive, with all coxae, trochanters and femora sometimes variously marked with or entirely dark brown or blackish; apex of hind tibia sometimes blackish; T1 sometimes blackish at anterior 0.1–0.8. All black areas often turning to dark brown (087,060,048) or brown (117,074,054); orange areas at hind coxa sometimes brown or dark brown.

Comments. Structurally similar to M. bicolor sp. nov., which can be readily distinguished from M. teutonicus by the head and mesosoma entirely blackish (vs. with many yellow marks – see Fig. 59 ); hind tibia whitish on basal 0.2 (vs. deep yellow); areolet distinctly larger, APH 1.45 (vs. 0.93), distinctly higher than wide, AWH 0.79 (vs. 1.00); and ovipositor shorter, OST 1.07, dorsal valve with five moderately strong ridges (vs. OST 1.41, dorsal valve with four weak ridges). Similar in color pattern to M. lordos sp. nov., from which it can be differentiated by the hind coxa bright to dark orange (vs. yellow and blackish); orbital band shortly interrupted at dorsal margin of eye (vs. complete); T1 entirely bright to dark orange (vs. blackish, with anterior and posterior yellow marks); cell 1+2Rs distinctly larger, APH 0.93 (vs. 0.42), about as wide as high, AWH 1.00 (vs. distinctly wider than high, AWH 1.69; and posterior transverse carina of propodeum complete, though weak (vs. entirely absent). Also somewhat similar to M. semiaurantigaster sp. nov., from which it can be isolated by the hind coxa entirely orange (vs. yellowish and black); supra-clypeal area mostly blackish (vs. entirely yellowish); T1–3 entirely orange (vs. anteriorly blackish, with posterior yellowish stripe); T1 distinctly more triangular, T1WW 2.36 (vs. 1.51); and posterior transverse carina complete (vs. entirely absent).

Biology. Unknown.
