Female. Fore wing 4.5 mm. HEAD: Mandible densely covered with long hairs; MLW 2.36; MWW 0.36; dorsal tooth in front view projected upwards, much longer than ventral tooth; ventral tooth triangular. MSM 0.25. Clypeus almost entirely flattened, centrally straight; CHW 1.87; CWW 2.26; apical area medially concave, laterally with distinct triangular lobes, its margin very sharp, raised. Antenna with 21 flagellomeres; flagellum uniform; apex of apical flagellomere much narrower than base, distinctly tapered. Supra-antennal area shiny, scarcely punctate, not striate near antennal sockets, ventrally very weakly concave, medially with a distinct depression but without a distinct line. Occipital carina uniformly curved, apically very faint. Temple and gena moderately wide, gena regular (as in Fig. 260 View FIGURES 260–271. 260–261 ).

THORAX: Pronotum centrally glabrate, sparsely pilose at dorsal margin, shiny, impunctate, wrinkles at posterior margin vestigial; epomia very weak, distinct only after diverging from pronotal collar, short, ending far from dorsal margin of pronotum, after diverging from pronotal collar approximately straight. Mesoscutum strongly and uniformly convex, ovoid, 1.35 × as long as wide, glabrate, shiny, impunctate; notaulus reaching about 0.7 of mesoscutum length, weakly impressed, surface over notaulus not wrinkled; scuto-scutellar groove moderately deep, without wrinkles. Subalar ridge weakly projected; epicnemial carina reaching about 0.7 of distance to subalar ridge, ventrally straight, dorsally slightly curved; sternaulus complete but weak, weakly sinuous, smooth; scrobe moderately deep; 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 indistinct. Transverse sulcus at base of propodeum very wide, about 0.95 × as long as anterior area of propodeum, impunctate; metapleuron impunctate, without transverse wrinkles, sparsely pilose; juxtacoxal carina absent. Fore tibia distinctly swollen. Mesal lobe of t4 with 3–4 bristles. Hind coxa punctatecoriarious.

PROPODEUM: 1.27 × as long as wide, shiny, sparsely pilose; anterior area almost impunctate; spiracle elliptic, SWL 3.25; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles weak, very closely spaced, mostly complete, distinctly curved backwards; posterior transverse carina entirely absent.

WINGS: Fore wing vein 1-Rs+M distinctly sinuous, with bulla placed on basal 0.25; crossvein 1m-cu more or less uniformly curved, totally continuous with 1-Rs+M; vein 1M+Rs anteriorly straight, posteriorly curved; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.34 of its own length; vein 2Cua 0.16 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed mostly on posterior half; cell 1+2Rs small, APH 0.61, pentagonal, about as high as wide, AWH 0.92; 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 distinctly sinuous; 4-M spectral, irregular. Hind wing vein 1-M forming distinctly obtuse angle with vein Cua; vein 2-Rs tubular, apically spectral, reaching wing margin; HW1C 0.84; vein Cub distinctly convex on posterior half, forming straight angle with Cua; vein 2-1A reaching 0.55 of distance to posterior wing margin.

METASOMA: First tergite short, about 0.33 × as long as T2–8, strongly depressed, ventrolaterally rounded, dorsally glabrate, laterally sparsely pilose; T1LW 4.13; T1WW 1.3; spiracle on 0.47 of its length, slightly prominent; median depression elongate, distinct; lateral and median posterior depressions absent; ventrolateral carina absent. T2LW 1.49; T2WW 2.33; 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 0.91; ovipositor moderately stout, straight, basally cylindric, apically distinctly depressed; dorsal valve with five moderately strong ridges; ventral valve apex with 9 teeth, 1st, 2nd and 3th widely spaced; surface anterior to first tooth rugulose.

Color. Head and mesosoma dark brown and whitish; metasoma brown, orange and whitish. Head: dark brown (066,050,038); clypeus, mandible except apex, mouthparts, supra-clypeal area, scape and pedicel ventrally and complete orbital band, whitish (231,216,160); scape and pedicel dorsally dark brown; flagellum dark brown, blackish towards apex, apical flagellomere light brown; f9–15 entirely white, f8 and f16 partially white. Mesosoma: dark brown; pronotoum, propleuron, subcircular spot on mesoscutum, scutellum except posterior 0.15, tegula, subalar ridge, hypoepimeron, most of ventral portion of mesopleuron, mesosternum, dorsal division of metapleuron, transverse sulcus anteriorly, metapleuron, metasternum and arc-shaped 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 with small basal dark brown spot; mid tibia yellowish, ventrally brown on basal 0.4; mid t1–4 dark fuscous, t5 blackish; hind coxa whitish, with wide longitudinal black stripe; hind trochanters marked with whitish and brown, femur bright orange (228,153,048), basal 0.9 of tibia light orange, apical 0.1 of tibia and basal 0.3 of hind t1 blackish; apical 0.7 of t1 and t2–5 white. Metasoma: T1 dark brown, whitish at anterior 0.3 and posterior 0.2; S1 whitish; T2 anteriorly dark brown, medially orange, posteriorly whitish; T3–6 anteriorly brown (115,065,036), posteriorly whitish; T7–8 anteriorly brown, posteriorly light orange; S2–4 basally light orange, posteriorly whitish, S5–6 whitish.

Male. Fore wing 4.4 mm. Very similar to female, except for the following: antenna with 23–24 flagellomeres; epicnemium pale yellow at ventral 0.6; blackish marks on mesopleuron less extensive; hind tibia apically with extensive blackish marks; hind t1 blackish on basal 0.9.

Variation. Fore wing 4.5–5.3 mm long; hind coxa with one or two black stripes, dorsal one either more or less straight or somewhat S-shaped; hind tibia sometimes with distinct whitish basal mark; T2 sometimes anteriorly fulvous, lighter than T3–8.

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

Biology. Unknown.

Material examined. 4 ♀, 5 ♂♂. 1 ♂ from MEXICO, Sinaloa, 20 mi. E Concordia , 915 m, 12.VIII.1964, WRMMason ( CNCI) . 1 ♀ from COSTA RICA, Puntarenas, Golfito , 28.VI.1987, JBrambila ; 1 ♀, same data except 7 km SW Rincon, Pt. 1, 31.V–7.VI.1988, Malaise trap, BBrown & V. Berezovsky, 2nd growth vegetation . 3 ♂♂ from COSTA RICA, Guanacaste, San Rosa park, Riparian , 20.V.1978, D.H. Janzen ; 1 ♂, same data except 26.V.1978 . 2 ♀ from COSTA RICA, Heredia, La Selva, Pt. 1, 1–6.VII.1993, Malaise trap, B. Brown & D. Feener ( AEIC) .

Distribution. Recorded from northeastern Mexico to Costa Rica ( Fig. 358 View FIGURES 353–360 ). It seems to have a parapatric distribution with the very close species M. amazonensis .
