Antenna with 21 flagellomeres; flagellum uniform; apex of apical flagellomere much narrower than base, distinctly tapered. Supraantennal area shiny, impunctate, very weakly striate near antennal sockets, not distinctly concave or convex, with slight median line. Occipital carina uniformly curved, fading out at distance about as long as basal width of mandible from the hypostomal carina. Temple and gena narrow, gena regular (as in Fig. 260 View FIGURES 260–271. 260–261 ).

THORAX: Pronotum glabrous, shiny, impunctate, with weak and short wrinkles along posterior margin of collar (and posterior margin); epomia weak, complete, short, ending far from dorsal margin of pronotum, after diverging from pronotal collar approximately straight. Mesoscutum moderately and uniformly convex, subcircular, 1.22 × as long as wide, glabrate, shiny, impunctate; notaulus reaching about 0.65 of mesoscutum length, moderately impressed, surface over notaulus not wrinkled; scuto-scutellar groove moderately deep, without wrinkles. Subalar ridge weakly projected; epicnemial carina complete, reaching subalar ridge, distinctly sinuous; sternaulus complete but weak, strongly sinuous, smooth; scrobe very shallow; mesopleural suture without wrinkles. Mesosternum medially without transverse wrinkles or depressions; median portion of posterior transverse carina of the mesothoracic venter indistinct. Transverse sulcus at base of propodeum very wide, about 0.84 × as long as anterior area of propodeum, very weakly rugulose; metapleuron sparsely and finely punctate, covered with the same wrinkling of propodeum, however less regular, dorsally sparsely pilose, ventrally moderately 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 about their own diameter, changing to coriarious-colliculate at interior face.

PROPODEUM: 1.24 × as long as wide, shiny, sparsely pilose; anterior area almost impunctate; spiracle elliptic, SWL 3.00; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles moderately strong, very closely spaced, mostly complete, mostly slightly curved or somewhat sinuous; posterior transverse carina entirely absent.

WINGS: Fore wing vein 1-Rs+M distinctly sinuous, with bulla placed on basal 0.25; crossvein 1m-cu irregular, limit between 1m-cu and 1-Rs+M more or less traceable; vein 1M+Rs anteriorly straight, posteriorly curved; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.35 of its own length; vein 2Cua 0.25 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed mostly on posterior half; cell 1+2Rs small, APH 0.67, pentagonal, about as high as wide, AWH 1.12; crossvein 3r-m fully spectral, 2r-m and 3r-m subparallel, 3r-m distinctly shorter; vein 3-M about as long as 2-M; 4-Rs somewhat irregular, apically slightly upcurved; 4-M tubular, straight. Hind wing vein 1-M forming straight angle with vein Cua; vein 2-Rs tubular, apically spectral, reaching wing margin; HW1C 0.81; vein Cub almost straight, very slightly convex, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.81 of distance to posterior wing margin.

METASOMA: First tergite moderately long, about 0.36 × as long as T2–8, somewhat depressed, ventrolaterally rounded, dorsally glabrate, laterally moderately pilose; T1LW 3.65; T1WW 1.88; spiracle on 0.42 of its length, slightly prominent; median depression elongate, distinct; lateral and median posterior depressions absent; ventrolateral carina absent. T2LW 1.22; T2WW 2.18; thyridium very shallow, about as wide as high, without small circular depression just behind it; T2–8 covered with small, shallow foveae, densely and uniformly pilose. OST 1.05; ovipositor moderately stout, straight, basally cylindric, apically distinctly depressed; dorsal valve with four moderately strong ridges; ventral valve apex with 10 teeth, 1st and 2nd widely spaced; surface anterior to first tooth rugulose.

Color. Head black; meso and metasoma mostly bright orange (211, 105, 38). Head: black; scape and pedicel ventrally ferruginous; f9–13 entirely white, 8 and 14, partially white; mandible except apex and small basal triangle, palipi and supra-clypeal area whitish (241, 230, 204). Mesosoma: bright orange; fore and mid legs gradually darker towards apex, tarsi dark fuscous; hind tibia basal 0.6 light ferruginous, apical 0.4 blackish; hind tarsus white, except basal 0.2 of t1 and apical 0.4 of t5, blackish. Metasoma: mostly orange to fuscous; anterior 0.5 of T2–8 marked with dark fuscous or blackish.

Male. Unknown.

Variation. Fore wing 7.28–10.50 mm long. Scape and pedicel ventrally ferruginous to whitish; propodeum sometimes apically infuscated with black; hind tibia with up to apical 0.6 blackish; T1 usually marked with dark fuscous near spiracle; basal 0.5 of T2–8 dark orange to blackish, usually darker at T2–3. Metasoma bright orange to fuscous (172, 090, 046).

Comments. Similar to M. amarelus sp. nov., from which it can be differentiated mainly by having generally larger size, fore wing 7.28–10.50 mm long (vs. 4.75–5.58); T2–8 entirely orange or with weak fuscous or blackish marks (vs. with distinct basal dark brown marks); cluster of bristles at mesal lobe of hind t4 distinct, represented by numerous bristles (vs. small, reduced to 3–4 bristles); and fore wing crossvein present, though spectral (vs. absent). It does also resembles M. aurantius sp. nov., from which it can be separated by the ovipositor straight (vs. slightly upcurved); hind tibia apically blackish (vs. entirely yellowish); and epomia epicnemial carina complete (vs. epomia distinct only after diverging from collar and epicnemial carina reaching about 0.6 of distance to subtegular ridge).

Distribution. Recorded from several sites at the Brazilian Atlantic Forest, from Nova Teutonia (Santa Catarina) to Santa Maria de Jetibá (Espírito Santo), but also with one record in central Brazil (Mato Grosso), in an area of Cerrado, a savannah-like vegetation ( Fig. 298 View FIGURES 297–304 ). The lack of other records between Atlantic coast and central Brazil can be due to poor sampling effort at those regions, but it is noteworthy that M. apertus was not recorded after years-long collecting efforts at southern Bahia, eastern Minas Gerais or central São Paulo. Also, all of the northernmost records (at Rio de Janeiro and Espírito Santo) are from highlands, therefore with colder temperatures more similar to those at southern Brazil. Thus, the species seems to be more typical of areas with moderate temperatures.
