HEAD: Mandible densely covered with long hairs; MLW 2.4; MWW 0.56; dorsal tooth in front view projected upwards, much longer than ventral tooth; ventral tooth triangular. MSM 0.4. Clypeus almost entirely flattened, centrally concave; CHW 2.65; CWW 3; apical area medially concave, laterally with distinct triangular lobes, its margin very sharp, raised. Antenna with 24 flagellomeres; flagellum strongly flattened and compressed on apical 0.3; apex of apical flagellomere about as wide as base, not distinctly tapered. Supraantennal area mat, scarcely punctate, weakly rugulose near antennal sockets, ventrally and around ocelli distinctly concave, dorsally with very weak median line, ventrally fading. Occipital carina uniformly curved, fading out at distance shorter than basal width of mandible from the hypostomal carina. Temple and gena moderately wide, gena regular (as in Fig. 260 ). THORAX: Pronotum glabrous, shiny, puncticulate to densely punctate, ventrally weakly striate (variation); epomia weak, complete, short, ending far from dorsal margin of pronotum, after diverging from pronotal collar distinctly curved. Mesoscutum moderately convex, flattened posteriorly, ovoid, 1.25 × as long as wide, densely covered with short hairs, shiny, densely punctate; notaulus reaching about 0.65 of mesoscutum length, deeply impressed, surface over notaulus with weak and short transverse wrinkles; scuto-scutellar groove moderately deep, without wrinkles. Subalar ridge weakly projected; epicnemial carina reaching about 0.85 of distance to subalar ridge, almost straight; sternaulus moderately strong, wide and shallow at posterior 0.25, weakly sinuous, with weak vertical wrinkles; scrobe very shallow; mesopleural suture ventrally with weak longitudinal wrinkles, wrinkles dorsally vestigial. Mesosternum medially without transverse wrinkles or depressions; median portion of posterior transverse carina of the mesothoracic venter short and almost indistinct, arched backwards. Transverse sulcus at base of propodeum very wide, about 0.84 × as long as anterior area of propodeum, very weakly rugulose; metapleuron punctate-rugulose, dorsally with same wrinkling of propodeum, however less regular, dorsally moderately pilose, ventrally densely 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 about their own diameter. PROPODEUM: 1.31 × as long as wide, shiny, moderately pilose; anterior area scarcely punctate; spiracle elongate, SWL 5.6; anterior transverse carina medially slightly arched backwards. Propodeal wrinkles strong, closely spaced, mostly complete but sometimes medially irregular, mostly slightly curved or somewhat sinuous; posterior transverse carina faintly suggested as a stronger wrinkle. 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 entirely irregular; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.41 of its own length; vein 2Cua 0.48 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed on midlength; cell 1+2Rs of moderate size, APH 0.82, pentagonal, about as high as wide, AWH 1.19; crossvein 3r-m fully spectral, 2r-m and 3r-m parallel, about same length; vein 3-M distinctly shorter than 2-M; 4-Rs distinctly sinuous; 4-M tubular, irregular. Hind wing vein 1-M forming straight angle with vein Cua; vein 2-Rs entirely tubular, apically weaker, reaching wing margin; HW1C 0.91; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.93 of distance to posterior wing margin. METASOMA: First tergite moderately long, about 0.41 × as long as T2–8, approximately cylindrical, ventrolaterally rounded, dorsally glabrate, laterally moderately pilose; T1LW 4.18; T1WW 1.57; spiracle on 0.51 of its length, distinctly prominent; median depression subcircular, distinct; lateral and median posterior depressions absent; ventrolateral carina absent. T2LW 1.63; T2WW 2.17; thyridium longer than wide, without small circular depression just behind it; T2–8 minutely coriarious, moderately and uniformly pilose except glabrate posterodorsal area in T2–3. OST 1.66; ovipositor moderately stout, straight, basally cylindric, apically distinctly depressed; dorsal valve with five moderately strong ridges; ventral valve apex with 8 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth rugulose. Color . Head and mesosoma mostly orange, metasoma black and whitish. Head: orange; pedicel and flagellum blackish except for f7–8 entirely white, f9–10 partially white; clypeus, mandible except apex, palpi, supra-clypeal area and weak orbital band around temple and gena, pale yellow (238,222,153); mandible apex blackish. Mesosoma: uniformly orange (216,115,046); fore and mid legs lighter towards apex, fore tarsus pale yellow; second hind trochanter fuscous, hind femur and tibia dark brown except ventral face of femur anteriorly; basal 0.5 of hind t1 dark brown; apical 0.5 and t2–5 whitish. Metasoma: T1 orange with posterior 0.5 of postpetiole brownish; T2–7 black, laterally white, with posterior semicircular whitish mark, T8 entirely black; metasomal sternites white with lateral black mark. Male . Fore wing 10.49–13.52 mm long. Very similar to female, except for the following: antenna with 31 flagellomeres; propodeal crests almost indistinct, blackish marks on T1 usually less extensive. Variation . Fore wing 10.71–16.66 mm . Orbital band sometimes complete, though weak, sometimes almost indistinct; clypeus, supra-clypeal area, mandible and malar space sometimes light orange; pronotal wrinkles sometimes very weak; mesopleuron whether covered with several very weak wrinkles or only densely punctate; fore t5 and mid t2–5 sometimes dark fuscous hind tochantellus completely orange to almost entirely blackish; hind tibia sometimes basally yellowish or whitish; dark mark on T1 laterally sometimes extending at posterior 0.5; T1 sometimes posteriorly. Specimen from Ecuador with T1 shorter, only slightly longer than T2. Comments . Very similar to M. albiaterartus sp. nov. , from which it can be differentiated by having supraantennal area, vertex and occiput bright orange (vs, black); orbital band weak and widely interrupted (vs. distinct and complete); whitish posterior marks at T2–8 medially subcircular (vs. straight), flagellum with uniform width (vs. flattened and widened at subapical 0.3); posterior carina of propodeum not forming sublateral crests, only faintly suggested as a stronger wrinkle (vs. distinct as weak sublateral crests); and anterior area of propodeum with a cluster of median punctures (vs. uniformly and scarcely punctate).
