Subalar ridge moderately projected; epicnemial carina reaching about 0.85 of distance to subalar ridge, distinctly sinuous; sternaulus moderately strong, wider on posterior apex, strongly sinuous, smooth; scrobe very shallow; mesopleural suture with weak longitudinal wrinkles along entire length. Mesosternum medially without transverse wrinkles or depressions; median portion of posterior transverse carina of the mesothoracic venter short and almost indistinct, straight. Transverse sulcus at base of propodeum very wide, about 0.85 × as long as anterior area of propodeum, impunctate; metapleuron sparsely and finely punctate, without transverse wrinkles, moderately pilose; juxtacoxal carina represented by very short ridges. Fore tibia distinctly swollen. Mesal lobe of t4 with a distinct cluster of stout bristles. Hind coxa with weak punctures separated by more than their own diameter.

PROPODEUM: 1.16 × as long as wide, shiny, sparsely pilose; anterior area moderately punctate; spiracle elliptic, SWL 2.89; anterior transverse carina medially straight. Propodeal wrinkles very weak and restricted to posterior half of posterior area, closely spaced, each wrinkle incomplete, 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 more or less uniformly curved, limit between 1m-cu and 1-Rs+M clearly traceable; vein 1M+Rs anteriorly straight, posteriorly weakly curved; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.24 of its own length; vein 2Cua 0.36 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed mostly on posterior half; cell 1+2Rs of moderate size, APH 0.96, pentagonal, about as high as wide, AWH 1.07; crossvein 3r-m fully spectral, 2r-m and 3r-m distinctly convergent, 3r-m distinctly shorter; vein 3-M about as long as 2-M; 4-Rs distinctly sinuous; 4-M tubular, slightly curved backwards. Hind wing vein 1-M forming distinctly obtuse angle with vein Cua; vein 2-Rs tubular, apically spectral, reaching wing margin; HW1C 0.95; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.78 of distance to posterior wing margin.

METASOMA: First tergite moderately long, about 0.4 × as long as T2–8, strongly depressed, ventrolaterally rounded, dorsally glabrate, laterally moderately pilose; T1LW 2.81; T1WW 1.63; spiracle on 0.52 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 0.95; T2WW 2.51; thyridium longer than wide, without small circular depression just behind it; T2–8 covered with small, shallow foveae, densely and uniformly pilose. OST 1.33; ovipositor moderately stout, straight, basally cylindric, apically distinctly depressed; dorsal valve with four moderately strong ridges; ventral valve apex with 8 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth rugulose.

Color. Head, mesosoma and metasoma black and whitish. Head: black; clypeus, mouthparts, malar space, supra-clypeal area and complete orbital band, whitish (228,212,141); scape and pedicel ventrally brown; f8–14 entirely white, f7 and f15 partially white. Mesosoma: mostly whitish; posterior semi-circular mark on propodeum, mesoscutum except subcircular spot, scuto-scutellar groove, both axillary through, scutellum posteriorly, axillar carinae medially, postscutellum, epicnemium, area of mesopleuron just ventral to subalar ridge, scrobe, mesopleural suture, posterior apex of sternaulus, transverse sulcus, posterior spot on metapleuron, anterior border and lateral borders of propodeum and posterior ovoid, somewhat pointed, spot on propodeum, black; fore leg whitish, darker towards apex, dorsal face of femur and tibia pale orange with brownish stripe on basal 0.6, t5 brown; mid leg pale orange (228, 178, 083) except whitish spot at coxa and tarsus brownish, t5 blackish; hind tibia pale orange with posterior whitish spot and black lateral mark on basal 0.5; hind trochanters, femur and tibia pale orange, apical 0.05 of tibia dark brown; basal 0.2 of t1 and t5 dark brown, remainder of tarsus whitish. Metasoma: black, turning to dark brown towards apex; T1 whitish, median 0.3 dorsally black; T2–8 with posterior whitish stripes; S1–6 whitish, S2–6 with progressively smaller lateral brownish marks.

Male. Not examined. According to Kasparyan & Ruíz (2008), similar to female, except for the following: fore wing 6.8 mm long; antenna with 24 flagellomeres; scape ventrally, mandible, fore and mid coxae and trochanters, whitish; hind tarsus white except basal 0.2 of t1, black.

Comments. Similar to M. opacus sp. nov. and to some specimens of M. discoidalis . It can be differentiated from both species, among other characters, by having T7–8 much longer than T5–6 (vs. about same length); and ovipositor longer, OST 1.33 (vs. 0.61–0.90), moderately stout, dorsal valve with four moderately strong ridges (vs. slender, dorsal valve without ridges). It can be additionally isolated from M. opacus by the posterior blackish mark on propodeum somewhat lanceolate, strong (vs. ovoid, weak); hind tibia pale orange, blackish on apical 0.05–0.20 (vs. pale to bright yellow on basal 0.4, blackish on apical 0.6); and T1 mostly whitish, except dorsal blackish spot at median 0.3 (vs. laterally entirely blackish, dorsally blackish at median 0.4–0.6). It can also be further separated from M. discoidalis by the mandible entirely black (vs. usually basally yellow); spiracle of propodeum elliptic, SWL 2.89 (vs. elongate, SWL 6.75); and propodeal wrinkles very weak and restricted to posterior half of posterior area (vs. anteriorly moderately strong, posteriorly strong).

Biology. Unknown.
