OST 1.02; ovipositor slender, slightly sinuous (check), basally cylindric, apically distinctly depressed; dorsal valve with four moderately strong ridges; ventral valve apex with 7 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth rugulose.

Color. Head, mesosoma and metasoma black and pale yellow. Head: black; clypeus, mandible except apex, mouthparts, malar space, supra-clypeal area, scape and pedicel ventrally and complete orbital band, pale yellow (236,213,130); scape and pedicel dorsally and flagellum basally, light brown, flagellum turning to blackish towards apex; f9–15 entirely white, f16 partially white, f8 with small apical whitish mark. Mesosoma: mostly pale yellow; small posterior mark on pronotum, mesoscutum except subcircular spot, scuto-scutellar groove, scutellum posteriorly, axillar carinae medially, postscutellum, dorsal 0.4 of epicnemium, area of mesopleuron just ventral to subalar ridge, dorsal portion of hypoepimeron and scrobe, mesopleural suture, ventral margin of mesopleuron, anterior area and most of posterior area (medially arched backwards), black; fore and mid legs pale yellow; mid coxa with lateral longitudinal black mark on apical 0.8, apically wider; mid trochanters ventrally dark brown; dorsal face of fore and mid femora pale orange, with brown stripe on basal 0.8; tibiae with brown ventral stripe on basal 0.9; mid tarsus fuscous, both t5 dark brown; hind coxa pale yellow, small anterior spot and lateral longitudinal stripe which is basally and apically widened, black; hind trochanters basally black, apically pale yellow; hind femur dark brown on basal 0.25 and ventral face of apical 0.4, dorsal face pale orange at median 0.7, ventral face pale yellow at median 0.35; basal 0.75 of hind tibia pale yellow, gradually turning to blackish on apical 0.25; basal 0.3 of t1 and apical 0.25 of t5, blackish; remainder of tarsus whitish. Metasoma: black; p 0.3 of T1, posterior stripes at T2–3, anterior and lateral portions of T4, lateral marks at T5–6 and 8, all T7 except anterior margin, pale yellow; S1–6 pale yellow, S2–6 with brownish lateral marks.

Male. Fore wing 4.07–7.71 mm long. Very similar to female, except for the following: antenna with 20–22 flagellomeres; black mark at fore coxa very small, S1 blackish; transverse sulcus entirely black; posterior area of propodeum almost entirely black, black area medially usually reaching posterior margin.

Variation. Fore wing 3.81–7.97 mm long. Antenna with 21–23 flagellomeres, flagellum sometimes basally dark brown; white band sometimes ending only 2–3 flagellomeres before apex; pronotum sometimes entirely pale yellow; portion of notaulus posterior to subcircular spot sometimes pale yellow; small black spot at scrobe not connected to anterior black area on mesopleuron; longitudinal mark at mid coxa sometimes extending to its base; anterior mark at hind coxa sometimes extended longitudinally as a small stripe, basally connected with lateral stripe; hypoepimeron sometimes entirely pale yellow, black mark at hind t5 sometimes almost indistinct. Specimens from Manaus with scrobe more distinctly convex, one of them with epicnemium entirely black and black area of mesopleuron expanded to about 0.5 of its surface. Specimens from Bahia with dark brown areas at hind leg turning to black, hind tibia distinctly gray at median 0.5 and black area of mesopleuron covering 0.4-0.6 of its surface, in one specimen including area over sternaulus; all pale yellow tones sometimes turning to whitish (240,224,157) or bright light yellow.

Comments. Readily recognized by the color pattern of hind femur and metasoma – the hind femur is dark brown at base and apex, with median portion dorsally light brown, ventrally yellowish; and the metasoma have the T4 anteriorly yellowish, with posterior blackish subcircular mark, T5–6 blackish with lateral yellowish marks and T7 almost entirely yellowish. Except for these features, is very similar to M. campanulatus sp. nov., from which it can be further differentiated by having central yellow mark on mesopleuron not connected to yellow subalar ridge (vs. connected); anterior area of propodeum entirely black (vs. with sublateral yellowish spots); T1 dorsally black at anterior 0.7 (vs. yellowish or whitish at anterior 0.25); ventral tooth of mandible distinct, rhomboid (vs. indistinct); and propodeal wrinkles distinctly curved backwards (vs. anteriorly and posteriorly slightly sinuous, median wrinkles medially strongly arched forwards, bell-shaped).

Biology. Unknown.

Etymology. Latinized form of “complex”, added to the Latin femur; in reference to the peculiar color pattern of the femur.
