Color. Head black, mesosoma orange, whitish and black, metasoma orange. Head: black; clypeus, mandible except apex, mouth parts, supra-clypeal area, malar space and very wide, complete orbital band (covering gena entirely), whitish (238,220,158); scape and pedicel dark brown, flagellum blackish, f6–10 entirely white, f11 partially white. Mesosoma: orange (222,125,052), slightly lighter at hypoepimeron and posterior area of propodeum; propleuron, collar and anterior margin of pronotum (near epomia), subcircular spot on mesoscutum, tegula, subalar ridge, scutellar carina, scutellum, axillar carina and dorsal division of metapleuron, pale yellow (233,211,112); fore coxa, tibia and tarsus, mid tibia and basal 0.75 of hind tibia, pale yellow; mid tarsus fuscous; apical 0.25 of hind tibia, tibial spurs and basal 0.25 of t1 blackish; t2–4 white; t5 blackish. Mesosoma: orange.

Male. Fore wing 4.42–7.28 mm long. Similar to female, but: scape and pedicel ventrally yellowish; antenna with 23–24 flagellomeres; f9–12 entirely white, f6–8 partially white, f13–17 with progressively smaller dorsal white marks; occiput almost entirely pale yellow, black only behind vertex; pronotum entirely pale yellow; mesopleuron except anterior corner and mesosternum completely whitish; propodeum apically pale yellow; fore and mid coxae, trochanters, anterior face of tibiae and tarsi, whitish; basal 0.4 of hind tibia white, apical 0.6 blackish.

Variation. Fore wing 6.36–8.48 mm long. Antenna sometimes with 20 flagellomeres; ventral corner of pronotum sometimes orange; dorsal division of metapleuron sometimes orange; posterior area of propodeum sometimes pale yellow laterally; hind tibia sometimes not blackish apically, and base of t1 orangish; postscutellum sometimes blackish; one specimen with scape and pedicel fulvous, anterior corner of mesopleuron black, spot on mesopleuron oval, wider than long, hind tibia medially orange between yellow and blackish areas. Meso and metasoma light orange (228,152,054) to deep orange (194,085,043).

Comments. Very similar to M. laevilatus sp. nov., from which it can be differentiated by having posterior transverse carina complete (vs. absent); propodeal wrinkles very weak anteriorly to posterior transverse carina, posteriorly strong, moderately closely spaced (vs. moderately strong and very closely spaced); spiracle of propodeum elliptic, SWL 2.57 (vs. elongate, SWL 4.00); areolet about as wide as high, AWL 0.97 (vs. distinctly higher than wide, AWH 0.66); and scape ventrally without whitish spot (vs. whitish spot present). Also superficially similar to M. convexus sp. nov., from which it can be isolated by having T2–8 bright to deep orange (vs. black, with posterior whitish stripes); propodeal wrinkles as described above (vs. moderately strong and very closely spaced); orbital band complete (vs. widely interrupted at gena); scape completely blackish (vs. with ventral whitish spot); and epomia complete (vs. distinct only after diverging from collar).

Biology. Unknown.

Distribution. Widely distributed along areas of open vegetation in South America ( Fig. 355 ). It is recorded from the Brazilian the semi-arid Caatinga, the savannah-like Cerrado and reaching argentine Patagonia at south, with one record in Bolivia. It was not recorded at the more coastal Atlantic rainforest even after extensive sampling at this biome.
