Antenna with 21 flagellomeres; flagellum uniform; apex of apical flagellomere about as wide as base, not distinctly tapered. Supra-antennal area shiny, centrally with coarse punctures and rugulosites, not striate near antennal sockets, ventrally very weakly concave, with slight median line. Occipital carina uniformly curved, fading out at distance about as long as basal width of mandible from the hypostomal carina. Temple and gena moderately wide, gena somewhat swollen and projected (as in Fig. 261).   
THORAX: Pronotum glabrous, shiny, impunctate, wrinkles at posterior margin vestigial; 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.

Fore tibia distinctly swollen. Mesal lobe of t4 with 3–4 bristles. Hind coxa entirely coriarious.  
PROPODEUM: 1.41 × as long as wide, shiny, sparsely pilose; anterior area coriarious-foveate; spiracle elliptic, SWL 3.33; anterior transverse carina medially straight. Propodeal wrinkles moderately strong, very closely spaced, mostly complete, anteriorly and posteriorly slightly sinuous, median wrinkles medially strongly arched forwards, bell-shaped; 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 weakly curved; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.38 of its own length; vein 2Cua 0.47 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed mostly on posterior half; cell 1+2Rs small, APH 0.47, pentagonal, about as high as wide, AWH 1.16; crossvein 3r-m fully spectral (and almost indistinct), 2r-m and 3r-m subparallel, about same length; vein 3-M distinctly longer than 2-M; 4-Rs almost straight; 4-M semi-spectral, slightly curved backwards. Hind wing vein 1-M forming straight angle with vein Cua; vein 2-Rs tubular, apically spectral, reaching wing margin; HW1C 1.25; vein Cub distinctly convex on posterior half, forming straight angle with Cua; vein 2-1A reaching 0.7 of distance to posterior wing margin.  
METASOMA: First tergite short, about 0.29 × as long as T2–8, approximately cylindrical, ventrolaterally angled, dorsally glabrate, laterally moderately pilose; T1LW 3.87; T1WW 1.33; spiracle on 0.42 of its length, slightly prominent; median depression elongate, distinct; median posterior depression absent; lateral depressions elongate, distinct; ventrolateral carina absent, but traceable as limit between lateral and ventral portions. T2LW 1.55; T2WW 2.17; thyridium longer than wide, without small circular depression just behind it; T2–8 covered with small, shallow foveae, densely and uniformly pilose. OST 1.04; ovipositor slender, straight, basally cylindric, apically distinctly depressed; dorsal valve with four moderately strong ridges; ventral valve apex with 8 teeth, 1st, 2nd and 3th widely spaced; surface anterior to first tooth rugulose.  
 Color. Head and mesosoma black and pale yellow, metasoma dark brown and pale yellow. Head: black; clypeus, mandible except apex, mouthparts, malar space, supra-clypeal area, ventral spot at scape and complete orbital band, pale yellow (237,219,153); scape and pedicel dorsally and flagellum basally, dark brown, flagellum turning to blackish towards apex; f11–15 entirely white, f10 and f16 mostly white, f17 with small basal whitish mark. Mesosoma: mostly pale yellow; small posterior mark on pronotum, sparse marks at mesoscutum, scutoscutellar groove, scutellum posteriorly, axillar carinae medially, postscutellum, epicnemium, dorsal margin of mesopleuron, scrobe, mesopleural suture, ventral margin of mesopleuron and lateral posterior mesosternum, anterior area of propodeum except lateral ovoid spot and about 0.5 of posterior area (medially arched backwards), black; most of mesoscutum dark brown (061,051,038), with central yellow mark partially covering notaulus and with weak yellowish longitudinal dash; fore and mid coxae, mid first trochanter, ventral face of fore and mid first trochanter mostly dark brown, with sparse yellowish marks; fore and mid second trochanters ventrally dark brown, dorsally pale yellow; dorsal face of femora pale orange, with longitudinal brown stripe; tibiae ventrally with longitudinal brown stripe on basal 0.85; fore tarsus light fuscous, mid tarsus dark brown, fore and mid t5 blackish; hind coxa mostly pale yellow, basally blacks, with large longitudinal black stripe which is basally wider; hind first trochanter and dorsal face of second one, black; ventral face of second trochanter pale yellow; basal 0.1 of hind femur pale yellow, sub-basal and apical 0.1 blackish, median 0.7 bright orange (202,098,039) basal 0.25 of hind tibia, apical 0.8 of t1 and t2–4, whitish; apical 0.75 of tibia, basal 0.2 of t1 and t5, blackish. Metasoma: dark brown; anterior 0.25 dorsally and posterior 0.3 of T1 pale yellow; posterior stripes at T2–4 and T7, lateral marks at T5–6 and 8 and lateral portion of T8, pale yellow; T8 posteriorly ferruginous; S2–6 pale yellow with brownish lateral marks.   
 Male. Unknown.   
 Variation. Female from Santa Teresa with fore wing 5.68 mm long; antenna with 22 flagellomeres; f10 entirely white, f9 and 16 entirely blackish; mesoscutum with only a small posterior black mark, lateral yellow dashes very weak; lateral yellow spot at anterior area distinct only as small brownish mark; pale yellow portion of posterior area anteriorly narrow and pointed, instead of bell-shaped; propodeal wrinkles medially only weakly arched forwards, not distinctly bell-shapd; all pale yellow areas almost whitish (243,227,190).   
 Comments. Readily recognized by the propodeal wrinkles anteriorly and posteriorly slightly sinuous, median wrinkles medially slightly to strongly arched forwards, somewhat bell-shaped; anterior area of propodeum with sublateral yellowish spots; and pronotum with vestigial wrinkles restricted to ventral margin. Except for these features, is very similar to M. complexifemur sp. nov., from which it can be further differentiated by having hind femur mostly bright orange (vs. base and apex dark brown, median portion dorsally light brown, ventrally yellowish); central yellow mark on mesopleuron connected to yellow subalar ridge (vs. not connected); T1 dorsally yellowish or whitish at anterior 0.25 (vs. black at anterior 0.7); ventral tooth of mandible indistinct (vs. distinct, rhomboid); and T4 anteriorly blackish, posteriorly yellowish (vs. anteriorly yellowish, with posterior blackish subcircular mark).   
 Also similar to M. atrifoveus sp. nov., from which it can be additionally distinguished by having T1 short, about 0.29 × as long as T2–8 (vs. very long, about 0.47 × as long as T2–8); epicnemium almost entirely black (vs. mostly yellowish); T5–6 only with lateral yellowish marks (vs. with complete posterior yellowish stripe); and ovipositor dorsal valve with four moderately strong ridges (vs. without ridges).   
 Biology. Unknown.   
 Etymology. From the Latin campana, meaning “bell”; in reference to the bell-shaped median propodeal wrinkles in the holotype.   
 Material examined. 2 ♀. Holotype ♀ from BRAZIL, Espírito Santo, Alfredo Chaves, Picadão, Pt. 2, 8.X–15.X.2007, Malaise trap, COAzevedo et al. (UFES). Mounted on triangle point. Badly broken; left fore leg, right mid leg and left hind leg missing; right hind leg broken and re-glued to the specimen; right fore wing detached and re-glued to the triangle.   
 Paratype: 1 ♀ from BRAZIL, Espírito Santo, Santa Teresa, Propriedade rural, Pt. 1, 19–26.VIII.2007, Malaise trap, FGRampinelli et al. (UFES).   
 Distribution. Recorded only from two very close localities in the Atlantic Forest of Espírito Santo, southeastern Brazil (Fig. 309).
