Antenna with 28 flagellomeres; flagellum uniform; apex of apical flagellomere much narrower than base, distinctly tapered. Supra-antennal area mat, coriarious, very weakly striate near antennal sockets, ventrally and around ocelli distinctly concave, without median line. Occipital carina dorsally acuminate, 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 moderately pilose, shiny, minutely rugulose, with moderate striation along posterior margin and collar; epomia almost indistinct, distinct only after diverging from pronotal collar, short, ending far from dorsal margin of pronotum, after diverging from pronotal collar approximately straight. Mesoscutum moderately convex, flattened posteriorly, ovoid, 1.24 × as long as wide, densely covered with short hairs, mat, densely punctulate; notaulus reaching about 0.74 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 weakly projected; epicnemial carina reaching about 0.7 of distance to subalar ridge, more or less uniformly curved; sternaulus complete and strong, wider on posterior apex, strongly sinuous, with weak vertical wrinkles; scrobe very shallow; mesopleural suture ventrally with strong longitudinal wrinkles, wrinkles dorsally weak. Mesosternum medially with short transverse wrinkles; median portion of posterior transverse carina of the mesothoracic venter short and almost indistinct, distinctly arched forwards. Transverse sulcus at base of propodeum very wide, about 0.76 × as long as anterior area of propodeum, laterally with strong longitudinal wrinkles, medially weakly rugulose; metapleuron minutely rugulose, without transverse wrinkles, densely covered with very short hairs; juxtacoxal carina represented by very short ridges. Fore tibia weakly swollen. Mesal lobe of t4 with a distinct cluster of stout bristles. Hind coxa entirely coriarious.

PROPODEUM: 1.09 × as long as wide, mat, densely pilose; anterior area asperous and densely punctulate; spiracle elliptic, SWL 3.17; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles vestigial, most of posterior area areolate-rugulose; posterior transverse carina distinct, medially interrupted, forming weak sublateral crests.

WINGS: Fore wing vein 1-Rs+M distinctly sinuous, with bulla placed on basal 0.4; crossvein 1m-cu more or less uniformly curved, limit between 1m-cu and 1-Rs+M clearly traceable; vein 1M+Rs anteriorly straight, posteriorly weakly curved; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.37 of its own length; vein 2Cua 0.82 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed on midlength; cell 1+2Rs of moderate size, APH 0.87, pentagonal, about as high as wide, AWH 0.87; 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 spectral, straight. Hind wing vein 1-M forming straight angle with vein Cua; vein 2-Rs tubular, apically spectral, reaching wing margin; HW1C 1.22; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (not curved); vein 2-1A reaching 0.91 of distance to posterior wing margin.

METASOMA: First tergite moderately long, about 0.41 × as long as T2–8, approximately cylindrical, ventrolaterally angled, uniformly, densely pilose; T1LW 5.48; T1WW 1.45; spiracle on 0.49 of its length, slightly prominent; median depression absent; lateral and median posterior depressions absent; ventrolateral carina weak, medially interrupted. T2LW 1.44; T2WW 2.74; thyridium much longer than wide, without small circular depression just behind it; T2–8 densely punctate and minutely and weakly coriarious, densely and uniformly pilose. OST 0.83; ovipositor slender, slightly sinuous, basally cylindric, apically distinctly depressed; dorsal valve with three very weak ridges; ventral valve apex with 8 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth rugulose.

Color. Head brownish orange, mesosoma brownish orange and dark brown, metasoma orange and dark brown. Head: brownish (113,064,049); clypeus, labrum, malar space, supra-clypeal area and gena ventrally, light orange (223,147,063); base of mandible, palpi, scape and pedicel, brown; narrow orbital band widely interrupted at malar space and dorsal margin of eye, whitish; apical 0.7 of mandible and flagellum blackish; f6–11 entirely white, f4 and f12 partially white. Mesosoma: brownish; propleuron, scutellum posteriorly, axillar carinae, postscutellum, ventral 0.3 of epicnemium, part of hypoepimeron, mesopleuron around anterior half of sternaulus, mesosternum, sparse marks at transverse sulcus, median portion of anterior area of propodeum and surface over anterior transverse carina, dark brown (075,053,043); legs mostly dark brown; ventral face for fore femur, fore and mid tibiae, whitish; dorsal face of fore and mid tibiae light orange; hind coxa with ventral orangish mark; sub basal 0.25 of hind tibia, apical 0.75 of t1, t2–4 and basal 0.5 of t5, white. Metasoma: orange (184,099,047); T1 brown, dorsally pale orange at anterior 0.25 and posterior 0.1; T2–3 brown at anterior 0.4; S2–6 with progressively smaller anterior brown areas.

Male. Unknown.

Comments. Similar to M. badius sp. nov., from which it can be differentiated by having mesosoma mostly mid brown, with mesosternum and coxae dark brown (vs. mesosoma and legs uniformly reddish brown); T4–7 entirely bright orange (vs. anteriorly dark brown, posteriorly brownish orange); propodeal wrinkles vestigial, most of posterior area areolate-rugulose (vs. distinct and moderately strong); ovipositor dorsal valve with three very weak ridges (vs. without ridges); surface anterior to first tooth of ventral valve rugulose (vs. not rugulose) and epomia after diverging from collar approximately straight (vs. distinctly curved).

Biology. Unknown.

Etymology. From the Latin paradoxus , meaning “strange”, “contrary to expectation”; in reference to the weak ridges on dorsal valve of ovipositor, a synampomorphy of the “Ridges” group, that finds it only homoplasy in this species.

Material examined. Holotype ♀ from COSTA RICA, Monteverde , 1700 m, 1–15.VI.1988, B.V. Brown ( AEIC). Pinned. Left flagellum missing; otherwise in good shape.

Distribution. Recorded only from the type locality, in Costa Rica ( Fig. 354 ).
