Antenna with 25 flagellomeres; flagellum uniform. Supra-antennal area mat, impunctate, distinctly striate near antennal sockets, ventrally and around ocelli slightly concave, dorsally with very weak median line, ventrally fading. Occipital carina uniformly curved, strong until almost reach hypostomal carina, apically very faint. Temple and gena narrow, gena regular (as in Fig. 260 ).

THORAX: Pronotum sparsely pilose, mat, impunctate, ventrally moderately striate; epomia weak, complete, short, ending far from dorsal margin of pronotum, after diverging from pronotal collar distinctly curved. Mesoscutum moderately and uniformly convex, ovoid, 1.27 × as long as wide, densely covered with short hairs, shiny, densely punctulate; notaulus reaching about 72 of mesoscutum length, moderately impressed, surface over notaulus with weak and short transverse wrinkles; scuto-scutellar groove moderately deep, without wrinkles. Subalar ridge moderately projected; epicnemial carina reaching about 0.85 of distance to subalar ridge, distinctly sinuous; sternaulus complete but weak, strongly sinuous, with vestigial vertical wrinkles; scrobe moderately deep; mesopleural suture with weak longitudinal wrinkles along entire length. Mesosternum medially with short transverse wrinkles; median portion of posterior transverse carina of the mesothoracic venter short and almost indistinct, straight. Transverse sulcus at base of propodeum very wide, about 1.00 × as long as anterior area of propodeum, with weak longitudinal wrinkles; metapleuron coriarious-rugulose, without transverse wrinkles, dorsally sparsely pilose, ventrally moderately pilose; juxtacoxal carina represented by very short ridges. Fore tibia not distinctly swollen. Mesal lobe of t4 with a distinct cluster of stout bristles. Hind coxa punctate-coriarious.

PROPODEUM: 1.13 × as long as wide, shiny, sparsely pilose; anterior area scarcely punctate; spiracle elongate, SWL 3.8; 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 distinct as very weak sublateral crests.

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 weakly curved; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.2 of its own length; vein 2Cua 0.46 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed on midlength; cell 1+2Rs small, APH 0.59, pentagonal, distinctly wider than high, AWH 1.21; crossvein 3r-m fully spectral, 2r-m and 3r-m distinctly convergent, 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 1.24; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.8 of distance to posterior wing margin.

METASOMA: First tergite short, about 0.35 × as long as T2–8, strongly depressed, ventrolaterally rounded, dorsally glabrate, laterally moderately pilose; T1LW 3.45; T1WW 1.63; spiracle on 0.49 of its length, distinctly 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 1.08; T2WW 2.26; thyridium much longer than wide, without small circular depression just behind it; T2–8 minutely and very weakly coriarious, densely and uniformly pilose. OST 0.72; ovipositor slender, slightly downcurved, basally cylindric, apically slightly depressed; dorsal valve without ridges; ventral valve apex with 9 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth rugulose.

Color. Head, mesosoma and metasoma black and whitish. Head: clypeus, mouthparts, malar space, supraclypeal area, ventral spots at scape and complete orbital band, whitish (243,239,227); f8–12 dorsally white, f10 entirely white, f7 dorsally white on apical 0.5, f13 with small basal white mark. Mesosoma: black; collar and dorsal margin of pronotum connected, propleuron laterally, subcircular spot on mesoscutum, scutellar carina, basal 0.8 of scutellum, tegula, subalar ridge, narrow central mark on mesopleuron, mesosternum, dorsal division of metapleuron, central 0.7 of metapleuron and narrow arc-shaped mark on propodeum, whitish; ventral border of metapleuron pale orange fore coxa and trochanter whitish, coxa with lateral longitudinal dark brown mark, first trochanter with dorsal dark brown mark; fore second trochanter and femur pale orange; fore tibia whitish with dorsal fuscous mark on basal 0.6; fore and mid tarsus blackish; mid leg except tarsus, bright orange; hind leg deep orange (187,073,044), extreme base and apex of hind tibia and tarsus except t4, blackish; hind t4 pale orange. Metasoma: black; basal 0.25 dorsally and apical 0.2 of T1, whitish; T2–8 with posterior and lateral whitish stripes; S1–6 whitish, S2–6 with progressively smaller lateral black marks.

Male. Unknown.

Variation. Fore wing 8.65–8.67 mm long. Specimen from Santo Domingo with mandible except apex whitish; antenna with 29 flagellomeres; pronotal wrinkles stronger; mesopleuron along epicnemial carina and metapleuron with weak but distinct wrinkles; central mark on mesopleuron wider, ventral margin of metapleuron only with small pale orange spot; arc-shaped mark on propodeum narrower, posterior black area distinctly lanceolate. Specimen from La Cumbre with mandible medially whitish.

Comments. Very similar to M. lunatus sp. nov., from which it can be differentiated by having postscutellum black (vs. yellow); yellow spot on mesopleuron elongate, somewhat sinuous (vs. distinctly C-shaped); mandible mostly blackish, with dorsal yellow spot (vs. mostly whitish); mesopleuron with weak longitudinal wrinkles along epicnemial carina, stronger on basal 0.3 (vs. without wrinkles along epicnemial carina); posterior transverse carina of propodeum distinct as very weak sublateral crests (vs. entirely absent); supra-clypeal area without blackish spot (vs. with blackish spot at females, males usually with blackish spot); scape ventrally with whitish spot (vs. without whitish spot at females, males with weak ventral spot).

Biology. Unknown.

Etymology. Latinized form of dominicana; in reference to Dominican Republic.
