Mesoscutum strongly and uniformly convex, ovoid, 1.35 × as long as wide, glabrate, shiny, impunctate; notaulus reaching about 0.71 of mesoscutum length, weakly impressed, surface over notaulus not wrinkled; scuto-scutellar groove moderately deep, without wrinkles. Subalar ridge weakly projected; epicnemial carina reaching about 0.7 of distance to subalar ridge, distinctly sinuous; sternaulus complete but weak, medially indistinct, weakly sinuous, smooth; scrobe very shallow; mesopleural suture ventrally with strong longitudinal wrinkles, wrinkles dorsally weak. Mesosternum medially with short transverse wrinkles; median portion of posterior transverse carina of the mesothoracic venter short and almost indistinct, slightly arched forwards. Transverse sulcus at base of propodeum very wide, about 1.13 × as long as anterior area of propodeum, medially with very weak transverse striation; metapleuron entirely coriarious, without transverse wrinkles, dorsally glabrate, ventrally sparsely pilose; juxtacoxal carina absent. Fore tibia distinctly swollen. Mesal lobe of t4 with a distinct cluster of stout bristles. Hind coxa with moderately strong punctures separated by more than their own diameter, internal face coriarious.

PROPODEUM: 1.1 × as long as wide, shiny, glabrate; anterior area almost impunctate; spiracle elongate, SWL 4.00; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles moderately strong, very closely spaced, mostly incomplete and overlapped, with some disperse complete wrinkles, mostly slightly curved or somewhat sinuous, anteriorly converging inwards; posterior transverse carina entirely absent.

Hind wing vein 1-M forming distinctly obtuse angle with vein Cua; vein 2-Rs tubular, apically spectral, reaching wing margin; HW1C 1.19; vein Cub almost straight, very slightly convex, forming straight angle with Cua; vein 2-1A reaching 0.91 of distance to posterior wing margin.

METASOMA: First tergite moderately long, about 0.38 × as long as T2–8, somewhat depressed, ventrolaterally rounded, dorsally glabrate, laterally moderately pilose; T1LW 3.47; T1WW 1.64; spiracle on 0.53 of its length, distinctly prominent; median depression elongate, very shallow; lateral and median posterior depressions absent; ventrolateral carina absent. T2LW 1.28; T2WW 1.92; thyridium longer than wide, without small circular depression just behind it; T2–8 minutely and very weakly coriarious, densely and uniformly pilose. OST 1.07; ovipositor moderately stout, straight, basally cylindric, apically distinctly depressed; dorsal valve with three moderately strong ridges; ventral valve apex with 6 teeth, 1st, 2nd and 3th widely spaced; surface anterior to first tooth rugulose.

Color. Head black, mesosoma orange (208,088,043), black and pale yellow (233,216,112), metasoma orange and fuscous. Head: black: f7–11 entirely white, f6 and 12 partially white; scape, ventrally clypeus, mouthparts, supra-clypeal area and narrow orbital band briefly interrupted at malar space, whitish; scape dorsally, pedicel and mandible except apex, brownish orange (285,115,065). Mesosoma: orange; pronotum, subalar ridge, dorsal 0.1 of mesopleuron, mesoscutum, scutellum posteriorly, postscutellum and postscutellum, black; collar, subcircular spot on mesoscutum, most of scutellum, and tegula, whitish; fore and mid legs gradually lighter towards apex; hind tibia yellow; hind tarsus white except t1 basally light yellow. Metasoma: bright orange; T2–3 weakly marked with dark fuscous at median portion.

Male. Fore wing 6.53 mm long. Similar to female, except for the following: mandible whitish (except apex); scape dorsally and pedicel dark brown; antenna with 25 flagellomeres; orbital band wide and complete, malar space whitish; hypoepimeron whitish; anterior area of propodeum slightly narrower than in female and dark brown; anterior transverse carina raised; apical 0.3 of mid t1, t2–5 and hind tibial spurs, blackish; T1 mostly dark brown, dorsally whitish on basal 0.4, at posterior 0.25 changing from bright orange to whitish; S1 orange; T2 anteriorly dark brown, at posterior 0.3 changing from orange to whitish; T3–6 and S2–5 anteriorly light brown, posteriorly with progressively longer orange stripes, T7 and S6 entirely orange.

Variation. Fore wing 8.57–9.74 mm long. Specimen from Serra do Navio with darker orange tones of mesosoma and metasoma (202,104,051), mandible mostly whitish, orbital band widely interrupted at gena, t1–2 light yellow and marks at T2–3 stronger. Specimen from Ibagué with body less pilose, almost glabrate.

Comments. Very similar to M. paraguayensis , from which it can be differentiated by having posterior transverse carina completely absent (vs. complete in M. paraguayensis ); propodeal wrinkles moderately strong and very closely spaced (vs. very weak anteriorly to posterior transverse carina, posteriorly strong, moderately closely spaced); spiracle of propodeum elongate, SWL 4.00 (vs. elliptic, SWL 2.57); areolet distinctly higher than wide, AWH 0.66 (vs. about as wide as high, AWL 0.97); and scape ventrally with whitish spot (vs. whitish spot absent). Also superficially similar to M. convexus sp. nov., from which it can be isolated by the areolet distinctly higher than wide (vs. about as wide as high, APH 1.09); T2–8 bright to deep orange (vs. black, with posterior whitish stripes); dorsal margin of mesopleuron black (vs. orange); supra-antennal area dorsally with weak median carina, ventrally fading (vs. without median carina); and epomia complete (vs. distinct only after diverging from collar).

Biology. Unknown.

Etymology. From the Latin words laevis, meaning “smooth”, and latus, meaning “ side”, “flank”; in reference to the mostly impunctate pronotum, mesopleuron and mesoscutum (as seen in lateral view).
