Female. Fore wing 11.19 mm. HEAD: Mandible with moderately sparse and long hairs; MLW 2.04; MWW 0.47; dorsal tooth in front view projected upwards, much longer than ventral tooth; ventral tooth triangular. MSM 0.24. Clypeus basally convex, apically abruptly flattened, centrally concave; CHW 2.65; CWW 2.04; apical area medially concave, laterally slightly projected, its margin very sharp, raised. Antenna with 25 flagellomeres; flagellum strongly flattened and compressed on apical 0.3; apex of apical flagellomere about as wide as base, not distinctly tapered. Supra-antennal area shiny, impunctate, not striate near antennal sockets, ventrally and around ocelli slightly concave, medially with a distinct depression but without a distinct line. 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 sparsely pilose, shiny, finely punctate, 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, 1.29 × as long as wide, sparsely pilose, shiny, scarcely punctate; notaulus reaching about 0.82 of mesoscutum length, moderately impressed, surface over notaulus with weak and short transverse wrinkles; scuto-scutellar groove moderately deep, with vestigial longitudinal wrinkles. Subalar ridge moderately projected; epicnemial carina reaching about 0.85 of distance to subalar ridge, almost straight; sternaulus complete but weak, strongly sinuous, with weak vertical wrinkles; scrobe very shallow; mesopleural suture ventrally with weak longitudinal wrinkles, wrinkles dorsally vestigial. Mesosternum medially with short transverse wrinkles; median portion of posterior transverse carina of the mesothoracic venter moderately long, slightly arched forwards. Transverse sulcus at base of propodeum very wide, about 0.82 × as long as anterior area of propodeum, medially with very weak transverse striation; metapleuron densely punctate, without transverse wrinkles, 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: 1.3 × as long as wide, shiny, moderately pilose; anterior area sparsely punctate, with a median cluster of punctures; spiracle elongate, SWL 6.33; anterior transverse carina medially straight. Propodeal wrinkles strong, closely spaced, mostly incomplete and overlapped, with some disperse complete wrinkles, mostly slightly curved or somewhat sinuous; posterior transverse carina distinct as very weak sublateral crests.

WINGS: Fore wing vein 1-Rs+M distinctly sinuous, with bulla placed on basal 0.4; 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 0.5 of its own length; vein 2Cua 0.55 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed on midlength; cell 1+2Rs small, APH 0.73, pentagonal, about as high as wide, AWH 1.18; 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 0.84; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.95 of distance to posterior wing margin.

METASOMA: First tergite moderately long, about 0.44 × as long as T2–8, approximately cylindrical, ventrolaterally rounded, dorsally glabrate, laterally moderately pilose; T1LW 3.69; T1WW 1.8; spiracle on 0.52 of its length, distinctly prominent; median depression elongate, distinct; lateral and median posterior depressions absent; ventrolateral carina absent, but traceable as limit between lateral and ventral portions. T2LW 1.29; T2WW 1.89; thyridium about as long as wide, without small circular depression just behind it; T2–8 minutely coriarious, moderately and uniformly pilose except glabrate postero-dorsal area in T2–3. OST 1.49; ovipositor moderately stout, straight, basally cylindric, apically distinctly depressed; dorsal valve with five moderately strong ridges; ventral valve apex with 9 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth rugulose.

Color. Head black, mesosoma mostly orange, metasoma orange, black and whitish. Head: black; f6–10 entirely white, f5 and f11–12 partially white; clypeus, mandible except apex, palpi, supra-clypeal area and complete orbital band, pale yellow (227,210,136). Mesosoma: orange (216,113,060); fore and mid apical tarsomere fuscous; hind second trochanter marked with dark brown; hind femur and tibia dark brown; hind tarsus white except basal 0.2 of t1, blackish. Metasoma: T1 orange, with posterior whitish stripe and small blackish mark just basad to stripe; T2–7 black with posterior whitish stripe, T4–7 also laterally whitish; T8 entirely black.

Male. Unknown.

Variation. Fore wing 11.05–11.90 mm long. Antenna with 23–25 flagellomeres. Most females with mesosoma light orange, with lateral portions of scutellum, scutellar carina and subalar ridge sometimes yellowish; hind femur ventrally orange to whitish; hind tibia sometimes with basal 0.6 whitish; T1 sometimes mostly black dorsally. Specimen from Rio Trinidad with metapleuron weakly rugulose.

Comments. Very similar to M. lissonotus , from which it can be differentiated by having supra-antennal area, vertex and occiput black (vs. bright orange); orbital band distinct and complete (vs. weak and widely interrupted); whitish posterior marks at T2–8 straight (vs. medially subcircular), posterior carina of propodeum distinct as weak sublateral crests (vs. not forming sublateral crests, only faintly suggested as a stronger wrinkle); and anterior area of propodeum uniformly and scarcely punctate (vs. with a cluster of median punctures).

Biology. Unknown.

Etymology. From the Greek previx para-, meaning “near”; in reference to its similarity to M. lissonotus .
