Antenna with 23 flagellomeres; flagellum uniform; apex of apical flagellomere much narrower than base, distinctly tapered. Supra-antennal area shiny, coriarious, distinctly striate near antennal sockets, ventrally and around ocelli slightly concave, without median line. Occipital carina uniformly curved, apically weak, meeting hypostomal carina far from mandible base. Temple and gena moderately wide, gena somewhat swollen and projected (as in Fig. 261 ).

THORAX: Pronotum moderately pilose, mat, almost entirely striate, ventrally with strong wrinkles; epomia absent. Mesoscutum strongly and uniformly convex, subcircular, 1.13 × as long as wide, densely covered with short hairs, mat, densely punctulate; notaulus reaching about 0.79 of mesoscutum length, moderately impressed, surface over notaulus with weak and short transverse wrinkles; scuto-scutellar groove moderately deep, with distinct longitudinal wrinkles. Subalar ridge weakly projected; epicnemial carina reaching about 0.85 of distance to subalar ridge (, apically faint), irregular; sternaulus moderately strong, wider on posterior apex, strongly sinuous, with weak vertical wrinkles; scrobe very shallow; mesopleural suture with strong longitudinal wrinkles along entire length. Mesosternum medially without transverse wrinkles or depressions; median portion of posterior transverse carina of the mesothoracic venter short and almost indistinct, slightly arched forwards. Transverse sulcus at base of propodeum moderately wide, about 0.68 × as long as anterior area of propodeum, anteriorly weakly colliculate, posteriorly with very weak longitudinal wrinkles; metapleuron minutely rugulose, without transverse wrinkles, densely covered with very short hairs; juxtacoxal carina represented by very short ridges. Fore tibia distinctly swollen. Mesal lobe of t4 with a distinct cluster of stout bristles. Hind coxa punctate-coriarious.

PROPODEUM: 1.12 × as long as wide, mat, densely pilose; anterior area asperous and densely punctulate; spiracle elliptic, SWL 3.44; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles anteriorly and laterally faint, posteriorly moderately strong, very closely spaced, mostly complete, often ramificated, mostly slightly curved or somewhat sinuous; posterior transverse carina entirely absent.

WINGS: Fore wing vein 1-Rs+M very weakly 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 curved; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.35 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 0.7, pentagonal, about as high as wide, AWH 0.9; crossvein 3r-m fully spectral, 2r-m and 3r-m subparallel, about same length; vein 3-M about as long as 2-M; 4-Rs somewhat irregular, apically slightly upcurved; 4-M spectral, weakly sinuous. Hind wing vein 1-M forming straight angle with vein Cua; vein 2-Rs tubular, apically spectral, reaching wing margin; HW1C 1.23; vein Cub distinctly convex on posterior half, forming straight angle with Cua; vein 2-1A reaching 0.84 of distance to posterior wing margin.

METASOMA: First tergite moderately long, about 0.35 × as long as T2–8, approximately cylindrical, ventrolaterally angled, uniformly, densely pilose; T1LW 6.96; T1WW 2.04; spiracle on 0.5 of its length, distinctly prominent; median depression absent; lateral and median posterior depressions absent; ventrolateral carina weak. T2LW 1.19; T2WW 2; thyridium longer than wide, without small circular depression just behind it; T2–8 densely punctate and minutely and weakly coriarious, densely and uniformly pilose. OST 1.04; ovipositor moderately stout, straight, basally cylindric, apically distinctly depressed; dorsal valve with four moderately strong ridges; ventral valve apex with 11 teeth, 1st, 2nd and 3th widely spaced; surface anterior to first tooth rugulose.

Color. Head dark brown, mesosoma light orange and dark brown, metasoma dark brown. Head: dark brown (078,061,050); clypeus centrally light fulvous; mouthparts, dorsal spot at supra-clypeal area and orbital band shortly interrupted at malar space, bright yellow (079,061,050); scape and pedicel ventrally light brown; f8–13 entirely white, f7 and f14 partially white. Mesosoma: light orange (211,099,042); most of pronotum, axillar carinae, postscutellum, anterior area of propodeum medially and area over anterior transverse carina, dark brown; small spot at pronotal collar, dorsal margin of pronotum, scutellar carina, posterior half of scutellum, tegula and subalar ridge, bright yellow; fore coxa and first trochanter dark brown; second trochanter,, femur, tibia and t1–4, whitish; fore femur dorsally and fore tibia ventrally with longitudinal brown stripes; fore and mid t5 blackish; mid and hind coxae with apical dark brown mark; mid trochanter with sparse dark brown marks; mid femur dark brown, except lateral face light orange; mid tibia dorsally whitish, ventrally dark brown; mid t1–4 light brown; hind trochanters and femur dark brown; extreme base and apical 0.75 of hind tibia, basal 0.5 of t1 and t4–5, blackish; sub-basal 0.2 of hind tibia, apical 0.5 of t1 and t2–3, whitish. Metasoma: dark brown; anterior 0.25 and subposterior 0.25 of T1, and S1, light orange; T1–4 and 7–8 with distinct posterior whitish stripes; T5–6 with almost indistinct lighter posterior lines; S2–3 light brown, S2–6 with posterior whitish stripes.

Male. Unknown.

Comments. Readily recognized by the following combination of characters: supra-clypeal area mostly blackish; pronotum dark brown except narrow whitish line at dorsal margin; mesopleuron and propodeum bright orange; hind coxa bright orange with apical dark brown mark; pronotum almost entirely striate; and epomia absent. More similar to M. argentinus , from which can be isolated by the characters above and also by the T5–6 without whitish or yellow marks, metasomal sternites mostly dark brown (vs. mostly yellowish) and ovipositor moderately stout, its dorsal valve with four moderately strong ridges (vs. ovipositor slender, dorsal valve without ridges).

Biology. Unknown.

Etymology. From the Greek prefix an-, meaning “not”, and epomia; in reference to the absence of epomia.

Material examined. Holotype ♀ from ECUADOR, Napo, Baeza , 1550 m, 15–19.V.1987, Brown & Coote ( AEIC). Pinned. Fore right wing ripped posteriorly; left fore wing detached and re-glued to the specimen; otherwise in good shape.

Distribution. Recorded only from the type locality, in Ecuador ( Fig. 296 ).
