Hind wing vein 1-M forming straight angle with vein Cua; vein 2-Rs tubular, apically spectral, reaching wing margin; HW1C 1.02; vein Cub distinctly convex on posterior half, forming straight angle with Cua; vein 2-1A reaching 0.73 of distance to posterior wing margin.

T2LW 0.98; T2WW 2.53; thyridium longer than wide, without small circular depression just behind it; T2–8 covered with small, shallow foveae, densely and uniformly pilose. OST 1.28; ovipositor moderately stout, straight, basally cylindric, apically distinctly depressed; dorsal valve with four moderately strong ridges; ventral valve apex with 6 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth rugulose.

Color. Head whitish, mesosoma whitish, orange and dark brown; metasoma mostly orange. Head: whitish (233, 223, 168); mandible, supra-antennal area except orbital band, vertex and occiput blackish; scape and pedicel orange (202, 110, 057); flagellum basally brownish, blackish towards apex, 8–13 entirely white, 7 partially white. Mesosoma: orange, generally darker dorsally and ventrally pale yellow (226, 192, 085); pronotum, subcircular spot on mesoscutum, scutellar carina, scutellum, tegula, subalar ridge, central 0.8 of mesopleuron, mesosternum centrally, dorsal division of metapleuron and transverse sulcus, whitish; posterior margin of pronotum at ventral 0.8, anterior margin of mesopleuron at dorsal 0.2, most of mesoscutum and small central spot over anterior transverse carina of propodeum, dark brown (151, 091, 063); postscutellum blackish; most of fore coxa, basal mark at mid coxa, anterior face of fore trochanters, femur, tibia and mid tibia, whitish; dorsal face of fore first trochanter and tibia marked with brownish; mid tarsus fuscous; apical 0.1 of hind tibia, tibial spurs and basal 0.3 of t1, blackish; apical 0.7 of t1 and t2–4, white; t5 fuscous. Metasoma: orange (214, 118, 047) anterior 0.18 dorsally and posterior 0.12 of T1 whitish; T2 with posterior pale yellow stripe.

Male. Unknown.

Variation. Fore wing 6.00– 7.35 mm long. Antenna sometimes with 21 flagellomeres; pronotal wrinkles sometimes very weak; mesoscutum sometimes light brown; propodeal wrinkles sometimes apically very weak and irregular; hind wing vein 2-1A sometimes very short, reaching only 0.3 of distance to wing margin; whitish posterior stripe at T2 sometimes indistinct.

Comments. More similar to M. copiosus sp. nov., from which it can be differentiated mainly by having mandible entirely blackish or dark brown (vs. mostly whitish); T2–4 bright orange except posterior whitish stripe at T2 (vs. T2–4 basally dark brown, medially orange and posteriorly whitish); metasomal sternites bright orange (vs. whitish); and propodeum bright orange with small whitish marks (vs. marked with black, whitish and orange). Also somewhat similar to M. ellipsicavus sp. nov., from which it can be readily isolated by the complete orbital band (vs. widely interrupted at gena); mesopleuron mostly whitish (vs, almost entirely bright orange); and hind coxa orange, without blackish mark (vs. with large longitudinal blackish mark). It does also resembles M. pallidus sp. nov., from which it can be separated by several features, mainly by T1–2 with posterior whitish stripes, T1 also dorsally whitish on basal 0.2 (vs. T1–2 entirely pale orange); hind wing vein Cub straight (vs. distinctly convex on posterior half, otherwise straight); and spiracle of propodeum elliptic, SWL 2.14 (vs. elongate, SWL 5.33).
