PROPODEUM: 1.26 × as long as wide, shiny, sparsely pilose; anterior area scarcely punctate; spiracle elliptic, SWL 3.00; anterior transverse carina medially straight. Propodeal wrinkles anteriorly very close and moderately strong, posteriorly stronger and more widely spaced, anterior and posterior wrinkles complete, central ones incomplete and overlapped, distinctly curved backwards; posterior transverse carina entirely absent.

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 0.46 of its own length; vein 2Cua 0.25 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed mostly on posterior half; cell 1+2Rs small, APH 0.729, pentagonal, about as high as wide, AWH 0.98; crossvein 3r-m absent; vein 3-M about as long as 2-M; 4-Rs very weakly sinuous; 4-M semispectral, irregular. Hind wing vein 1-M forming distinctly obtuse angle with vein Cua; vein 2-Rs entirely tubular, apically weaker, reaching wing margin; HW1C 1.01; vein Cub almost straight, very slightly convex, forming straight angle with Cua; vein 2-1A reaching 0.74 of distance to posterior wing margin.

METASOMA: First tergite short, about 0.34 × as long as T2–8, strongly depressed, ventrolaterally rounded, dorsally glabrate, laterally moderately pilose; T1LW 3.95; T1WW 1.45; spiracle on 0.49 of its length, distinctly prominent; median depression elongate, very shallow; median posterior depression absent; lateral depressions elongate, very shallow; ventrolateral carina absent. T2LW 1.75; T2WW 1.71; thyridium longer than wide, without small circular depression just behind it; T2–8 smooth between punctures, densely and uniformly pilose. OST 0.69; ovipositor moderately stout, straight, basally cylindric, apically distinctly depressed; dorsal valve with five moderately strong ridges; ventral valve apex with 11 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth rugulose.

Color. Head black, mesosoma black and whitish; metasoma mostly orange. Head: black; clypeus, mandible except apex, mouthparts, supra-clypeal area, scape and pedicel ventrally and complete orbital band, whitish (233, 222, 178); scape and pedicel dark brown; flagellum dark brown, blackish towards apex, ventrally lighter; f8–14 entirely white, f7 and f15 partially white. Mesosoma: black; pronotoum except small mark at posterior margin midlength, propleuron, subcircular spot on mesoscutum, scutellar carina, scutellum except posterior 0.05, tegula, subalar ridge, dorsal portion of hypoepimeron, most of ventral portion of mesopleuron, mesosternum, dorsal division of metapleuron, transverse sulcus except longitudinal median line, metapleuron, metasternum and arcshaped mark on propodeum, whitish; fore and mid tibia and fore trochanters whitish; fore femur and tibia ventrally whitish, dorsally orangish with narrow brown line; mid trochanters sparsely marked with whitish and brown; mid femur light orange, ventrally whitish on basal 0.2; mid tibia yellowish, mid t1–4 light fuscous, t5 blackish; hind coxa whitish, with wide longitudinal black stripe; hind trochanters marked with whitish and brown, femur bright orange (225,146,042), basal 0.8 of tibia yellowish, apical 0.2 and basal 0.3 of hind t1 blackish; apical 0.7 of t1 and t2–5 white. Metasoma: bright orange; anterior 0.4 and posterior 0.2 of T1 whitish, median portion black, laterally extending almost to tergite base; T2 with posterior white stripe.

Male. Fore wing 4.66–5.42 mm long. Differs from female essentially by the following: posterior blackish mark on propodeum medially triangular, reaching anterior black area, leaving only two oblique, ovoid yellow marks on propodeum; hind trochanters almost entirely dark brown; hind femur with small basal and apical blackish marks; blackish marks at hind tibia and t1 more extensive, covering apical 0.25 of tibia and basal 0.7 of t1; T1–7 and S1–6 anteriorly brown, with progressively shorter posterior white stripes.

Variation. Fore wing 5.82–6.69 mm long. Posterior portion of pronotum sometimes with black area covering up to 20% of its surface; mesopleuron and mesosternum sometimes mostly or entirely black, except for subalar ridge and small rounded spot at ventral mesopleuron; apical black area on propodeum sometimes almost indistinct; hind coxa sometimes marked with orangish ventrally to blackish longitudinal mark; T2–7 sometimes basally brown. One male specimen with T2 basally orange.

Comments. Very similar to M. propodeator , from which it can be differentiated by having T3–8 entirely bright orange (vs. anteriorly brown, posteriorly whitish); fore wing crossvein 3r-m entirely absent (vs. distinct, though spectral); hind wing vein Cub almost straight, very weakly convex (vs. distinctly convex on posterior half); supraantennal area without median depression (vs. with median depression); and mesosternum medially with short transverse wrinkles (vs. without transverse wrinkles).

Biology. Unknown.

Etymology. Latinized construction for “from Amazon”; in reference to its mostly Amazonian distribution.
