Mesosternum medially with short transverse wrinkles; median portion of posterior transverse carina of the mesothoracic venter short, slightly arched forwards. Transverse sulcus at base of propodeum very wide, about 0.9 × as long as anterior area of propodeum, laterally with weak longitudinal wrinkles, medially not wrinkled; metapleuron punctate-rugulose, dorsally with same wrinkling of propodeum, however less regular, densely pilose; juxtacoxal carina represented by very short ridges. Fore tibia weakly swollen. Mesal lobe of t4 with a distinct cluster of stout bristles. Hind coxa rugulose-coriarious.

PROPODEUM: 1.14 × as long as wide, shiny, moderately pilose; anterior area punctate-foveolate; spiracle elliptic, SWL 2.8; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles anteriorly very close and moderately strong, posteriorly stronger and more widely spaced, mostly complete, anteriorly strongly curved, posteriorly somewhat irregular; posterior transverse carina entirely absent.

WINGS: Fore wing vein 1-Rs+M distinctly sinuous, with bulla placed on basal 0.25; crossvein 1m-cu more or less uniformly curved, 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 0.43 of its own length; vein 2Cua 0.58 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed mostly on posterior half; cell 1+2Rs small, APH 0.43, pentagonal, about as high as wide, AWH 1.12; crossvein 3r-m fully spectral, 2r-m and 3r-m subparallel, about same length; vein 3-M almost indistinct; 4-Rs very weakly sinuous; 4-M tubular, straight. Hind wing vein 1-M forming straight angle with vein Cua; vein 2-Rs entirely tubular, apically weaker, reaching wing margin; HW1C 1.69; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.92 of distance to posterior wing margin.

METASOMA: First tergite moderately long, about 0.37 × as long as T2–8, approximately cylindrical, ventrolaterally rounded, dorsally sparsely pilose, laterally moderately pilose; T1LW 3.91; T1WW 1.47; spiracle on 0.5 of its length, slightly prominent; median depression elongate, very shallow; lateral and median posterior depressions absent; ventrolateral carina absent, but traceable as limit between lateral and ventral portions. T2LW 1.25; T2WW 2.7; thyridium longer than wide, without small circular depression just behind it; T2–8 minutely coriarious, with small, shallow foveae, densely and uniformly pilose. OST 0.66; ovipositor slender, straight, basally cylindric, apically slightly depressed; dorsal valve without ridges; ventral valve apex with 7 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth not rugulose.

Color. Head, mesosoma and metasoma black, marked with whitish. Head: black; clypeus except dorsal margin and median apical spot, mandible except apex, mouthparts, dorsal 0.5 of supra-clypeal area and complete orbital band, pale yellow (233,221,143); f8–13 entirely whitish, f7 and f14–15 almost entirely whitish. Mesosoma: black; collar, posterior 0.8 of dorsal margin of propodeum, subcircular spot on mesoscutum and longitudinal dash over notaulus, scutellar carina, scutellum, subalar ridge, two separate marks on mesopleuron, dorsal division of metapleuron, posterior 0.4 of metapleuron and ovoid lateral marks on propodeum, whitish; fore and mid coxae whitish with posterior brown spots; fore and mid first trochanters whitish with basal brown spot; fore and mid second trochanters and femora dark orange (184,088,047), fore femur with dorsal brownish stripe; fore and mid tibiae light fuscous; fore tarsus fuscous; fore and mid t5 and mid t1, blackish; mid t2–4, whitish; hind coxa black with longitudinal, wide, whitish stripe at posterior face; hind trochanters black, first one with apical yellow spot, second with apical orange spot; hind femur bright orange, apical 0.01 black; basal 0.25 of hind tibia, apical 0.75 of t1 and t2–4, whitish; apical 0.75 of hind tibia, basal 0.25 of t1and t5, dark brown. Metasoma: black; anterior 0.3 of T1 dorsally bright yellow; T1–8 and S1–7 with posterior bright yellow stripes.

Male. Fore wing 6.09 mm long. Very similar to female, except for the following: dark areas slightly lighter, dark brown; mid tibia with sparse brownish marks; f14–19 entirely white, f11–13 and f20 dorsally white.

Variation. Male from Colombia with supra-clypeal area entirely yellow and hind femur almost entirely blackish. Female from Colombia with supra-clypeal area yellow except for narrow black line between clypeus and supra-clypeal area; anterior portion of mesoscutum laterally with horizontal yellow dash; yellow mark at dorsal margin of pronotum wider; fore and mid femora and tibiae orangish yellow; mid tibia fore tibia more distinctly swollen; and ovipositor ventral valve teeth appearing somewhat worn, teeth hardly distinguishable. It may represent a different species, but a more representative series is needed to be sure.

Comments. Very similar to M. unimaculatus sp. nov., from which it can be differentiated by the supra-clypeal area black except orbital band (vs. yellow except for narrow black line between clypeus and supra-clypeal area); supra-antennal area not striate near antennal sockets, without median carina (vs. distinctly striate, with slight median carina); epomia moderately long, distinctly curved (vs. short, approximately straight); mesoscutum densely punctate (vs. minutely colliculate); fore tibia very weakly swollen (vs. distinctly swollen); propodeal spiracle elliptic, SWL 2.80 (vs. elongate, SWL 4.75).

Biology. Unknown.

Etymology. From the Latin macula, meaning “ spot ”, added to the prefix bi-, meaning “two”; in reference to the two separate central marks on mesopleuron.

Material examined. 2 ♀ 3 ♂♂. Holotype ♀ from from BRAZIL, Bahia, Iruberá, Fazenda Vale da Juliana, 26.I.2007, Malaise trap, JCardoso & JMaia, “ Banana Teste.” Mounted on triangle point. Tips of both antennae, right fore t2–5 and left mid leg apicad to coxa missing; otherwise in good shape.
