Female. Fore wing 9.37 mm. HEAD: Mandible with moderately sparse and long hairs; MLW 2; MWW 0.46; dorsal tooth in front view projected upwards, much longer than ventral tooth; ventral tooth triangular. MSM 0.28. Clypeus almost entirely flattened, centrally concave; CHW 2.87; CWW 4.05; apical area medially straight, laterally slightly projected, its margin very sharp, raised. Antenna with 23 flagellomeres. Flagellum uniform; apical flagellomere much narrower than base, distinctly tapered. Supra-antennal area shiny, scarcely punctate, not striate near antennal sockets, ventrally very weakly concave, dorsally with very weak median line, ventrally fading. Occipital carina dorsally distinctly bell-shaped, fading out at distance about as long as basal width of mandible from the hypostomal carina. Temple and gena moderately wide, gena somewhat swollen and projected (as in Fig. 261 ).

THORAX: Pronotum sparsely pilose, shiny, finely punctate, ventrally with strong wrinkles; epomia moderately strong, distinct only after diverging from pronotal collar, moderately long, ending near dorsal margin of pronotum, after diverging from pronotal collar distinctly curved. Mesoscutum moderately and uniformly convex, ovoid, 1.26 × as long as wide, anteriorly densely pilose, posteriorly sparsely pilose, shiny, asperous; notaulus reaching about 0.64 of mesoscutum length, moderately impressed, surface over notaulus with weak and short transverse wrinkles; scuto-scutellar groove deep, with distinct longitudinal wrinkles. Subalar ridge moderately projected; epicnemial carina reaching about 0.7 of distance to subalar ridge, irregular; sternaulus moderately strong, wider on posterior apex, weakly sinuous, with weak vertical wrinkles; scrobe very shallow; mesopleural suture with strong longitudinal wrinkles along entire length. Mesosternum medially with short transverse wrinkles; median portion of posterior transverse carina of the mesothoracic venter short, arched backwards. Transverse sulcus at base of propodeum very wide, about 0.8 × as long as anterior area of propodeum, impunctate; metapleuron moderately punctate, without transverse wrinkles, dorsally sparsely pilose, ventrally 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 moderately strong punctures separated by more than their own diameter.

PROPODEUM: 1.15 × as long as wide, shiny, moderately pilose; anterior area sparsely punctate, with a median cluster of punctures (and faintly coriarious); spiracle elongate, SWL 4.00; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles anteriorly very close and moderately strong, posteriorly stronger and more widely spaced, mostly complete, oblique and approximately straight; posterior transverse carina entirely absent.

WINGS: Fore wing vein 1-Rs+M distinctly sinuous, with bulla placed around its midlength; 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 0.42 of its own length; vein 2Cua 0.7 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed on midlength; cell 1+2Rs small, APH 0.56, pentagonal, distinctly wider than high, AWH 1.2; crossvein 3r-m fully spectral, 2r-m and 3r-m subparallel, about same length; vein 3-M distinctly shorter than 2-M; 4-Rs distinctly sinuous; 4-M tubular, straight. Hind wing vein 1-M forming distinctly obtuse angle with vein Cua; vein 2-Rs entirely tubular, apically weaker, reaching wing margin; HW1C 1.47; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.91 of distance to posterior wing margin.

METASOMA: First tergite moderately long, about 0.38 × as long as T2–8, somewhat depressed, ventrolaterally rounded, dorsally glabrate, laterally sparsely pilose; T1LW 3.17; T1WW 1.95; spiracle on 0.52 of its length, distinctly prominent; median depression elongate, distinct; median posterior depression absent; lateral depressions elongate, very shallow; ventrolateral carina absent, but traceable as limit between lateral and ventral portions. T2LW 1.07; T2WW 1.97; thyridium longer than wide, without small circular depression just behind it; T2–8 minutely coriarious, densely and uniformly pilose. OST 1.35; ovipositor moderately stout, straight, basally cylindric, apically slightly depressed; dorsal valve with four moderately strong ridges; ventral valve apex with 5 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth rugulose.

Color. Head, mesosoma and metasoma black with bright yellow marks. Head: black; clypeus except lateral margins, mouthparts, supra-clypeal area except small ventral spot, and complete (though much narrower at temple) orbital band, bright yellow (231,211,088); f7–10 entirely white, f11 dorsally white. Mesosoma: black; collar, median 0.6 of dorsal margin of pronotum, subcircular spot on mesoscutum, scutellar carina, scutellum except apical triangular mark, axillar carinae medially, tegula, subalar ridge and central mark on mesopleuron connected, anterior 0.7 of mesosternum, dorsal division of metapleuron, metapleuron except small anterior and posterior marks and arc-shaped mark on propodeum, bright yellow; fore and mid legs bright yellow, except longitudinal mark at mid coxa and posterior face of fore and mid coxae, first trochanters and femora; fore and mid t5 dark brown; hind tibia bright yellow with three longitudinal black stripes, anterior one extending on basal 0.5, median and posterior ones reaching apex of coxa; first trochanter bright yellow with basal black mark, second trochanter black, apically orange; hind femur orange at extreme base, otherwise blackish, with ventral face and dorsal longitudinal stripe bright yellow; hind tibia and tarsus uniformly bright yellow. Metasoma: black; T1 bright orange, median 0.4 black; T2–7 with posterior and lateral bright yellow marks, T8 with only lateral stripes; S–6 bright yellow, S2–3 with lateral brown marks.

Male. Generally similar to female, except for the following: dorsal margin of pronotum entirely bright orange; epicnemium except small blackish mark, area over sternaulus and mesosternum, bright yellow; fore coxa and first trochanter entirely bright yellow; mid coxa entirely yellow except small basal blackish spot; mid tarsus fuscous, darker apically; yellow areas at hind femur darker and more extensive; apical 0.2 of hind tibia and basal 0.2 of t1, blackish; hind tarsus lighter towards apex, apically whitish; T1 laterally almost entirely black; S2-7 blackish with posterior bright yellow stripes.

Variation. Fore wing 9.10–10.17 mm. Specimen from Honduras with spiracle only slightly prominent.

Comments. Very similar to M. grandis , from which it can be differentiated by having mandible entirely black (vs. basally yellow); yellow mark on propodeum distinctly arc-shaped (vs. propodeum with two lateral, ovoid yellowish marks); supra-antennal area not striate near antennal sockets (vs. distinctly striate); epomia long, though distinct only after diverging from collar (vs. short, complete); propodeal wrinkles oblique and approximately straight (vs. distinctly curved backwards); and cell 1+2Rs pentagonal, 2r-m and 3r-m with about the same size (vs. 1+2Rs subquadratic, 3r-m distinctly longer than 2r-m).

Biology. Unknown.
