T2LW 1.45; T2WW 2.06; thyridium longer than wide, without small circular depression just behind it; T2–8 covered with small, shallow foveae, densely and uniformly pilose. OST 0.98; ovipositor slender, straight, basally cylindric, apically slightly depressed; dorsal valve without ridges; ventral valve apex with 10 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth not rugulose.

Color. Head and mesosoma black and pale yellow, mesosoma dark brown 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 (228,215,116); f9–15 entirely white, f8 partially white. Mesosoma: black; collar and dorsal margin of pronotum connected, propleuron, subcircular spot on mesoscutum, scutellum, axillar carinae, postscutellum, tegula, subalar ridge, central mark on mesopleuron reaching ventral margin, hypoepimeron, mesosternum, dorsal 0.4 of mesepimeron, dorsal division of metapleuron, metapleuron except small ventral and posterior spots, and posterior subcircular mark on propodeum, pale yellow; fore and mid legs pale yellow, lighter at coxae and trochanters; mid first trochanter with dorsal and ventral dark brown marks; dorsal face of femora pale orange, with brown stripe apically narrower; fore tibia with weak brownish mark dorsally; mid tarsus and fore t5 dark brown; hind coxa pale yellow, anterior basal portion and lateral longitudinal stripe, black; hind first trochanter mostly dark brown, with orangish marks; second trochanter basally yellowish, apically orange; hind femur bright orange (209,127,061) with small basal yellow mark and apical blackish mark; basal 0.25 of hind tibia, apical 0.75 of t1, t2–4 and basal 0.8 of t5, whitish; apical 0.75 of hind tibia, basal 0.25 of t1 and apical 0.2 of t5, blackish. Metasoma: dark brown, lighter towards posterior tergites; anterior 0.4 dorsally and posterior 0.2 of T1, pale yellow; S1 pale yellow; T2–8 with posterior pale yellow stripes; S2–6 pale yellow, with progressively smaller brown lateral marks.

Male. Fore wing 5.03–7.37 mm long. Generally similar to female, except for the following: antenna with 24–28 flagellomeres; pronotum completely pale yellow, its dorsal margin anteriorly slightly concave; mesoscutum more strongly convex; epicnemium sparsely marked with black and pale yellow; mesopleuron distinctly concave at posterior portion (around scrobe), except hypoepimeron; central portion of mesopleuron somewhat swollen, projected; mesopleuron black only just ventrad to subalar ridge and between scrobe and hypoepimeron; black portion of posterior area of propodeum more extensive; hind second trochanter mostly blackish.

Variation. Fore wing 6.17–7.71 mm long. Antenna sometimes with 24 flagellomeres; axillary carinae sometimes brownish, postscutellum sometimes black; epicnemial carina dorsally with very weak to strong longitudinal wrinkles; yellow mark at hypoepimeron sometimes connected to central mark on mesopleuron; metapleuron from entirely punctate to almost entirely rugulose; anterior and ventral borders of metapleuron sometimes black; propodeal wrinkles sometimes somewhat irregular, anteriorly rugulose posterior yellow area on propodeum sometimes somewhat “lotus-shaped” (three basally connected triangles); mid femur sometimes entirely light orange; hind tibia with apical 0.6–0.8 blackish; males sometimes with small blackish mark on pronotum, epicnemium completely black to almost entirely yellow, small black areas on mesopleuron connected and apical stripes at T2–8 very narrow. Pale yellow areas sometimes whitish (232,216,166) or bright yellow (230,205,095).

Comments. Very similar to M. propodeator , from which it can be differentiated by the pronotum mostly black (vs. almost entirely whitish); surface over sternaulus black (vs. mostly whitish); hind coxa with two blackish marks, basally connected (vs. with a single, somewhat S-shaped longitudinal mark); ovipositor dorsal valve without ridges (vs. with five moderately strong ridges); first tergite long, about 0.51 × as long as T2–8, moderately depressed (vs. short, about 0.33 × as long as T2–8, strongly depressed); and antenna with 24–28 flagellomeres (vs. 21). It can be isolated from M. amazonensis sp. nov. by the characters above and by having T2–8 black, with posterior yellow marks (vs. bright orange, only T2 with posterior whitish stripe).

In the same work in which M. variegatus was described, Szépligeti (1916) proposed also M. tricolor , known from the male holotype. From the original description, no consistent differences can be identified between the two species. Both species were collected at the same site (Blumenau), and Szépligeti rarely described species based on the two sexes. Additionally, one male specimen of M. variegatus was found at the AEI with a handwritten note by H. Townes, stating “very close to M. tricolor Szé. ” Although the holotypes of these two species have not yet been seen, it seems most probable that these are synonyms, each sext having been described as a separate species. Therefore, M. tricolor is treated here as a synonym of M. variegatus . Since both species were published in the same work, the latter name is chosen to remain as the valid one in order to maintain a female specimen as the holotype of the valid name.

Biology. Unknown.
