 Female. Fore wing 11.12 mm. HEAD: Mandible densely covered with long hairs; MLW 1.93; MWW 0.44; dorsal tooth in front view projected upwards, much longer than ventral tooth; ventral tooth triangular. MSM 0.28. Clypeus almost entirely flattened, centrally concave; CHW 2.5; CWW 2.71; apical area medially concave, laterally with distinct triangular lobes, its margin very sharp, raised. Antenna with 24 flagellomeres; flagellum strongly flattened and compressed on apical 0.3; apex of apical flagellomere about as wide as base, not distinctly tapered. Supraantennal area shiny, scarcely punctate, very weakly striate near antennal sockets, ventrally and around ocelli distinctly concave, with slight 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 somewhat swollen and projected (as in Fig. 261).   
THORAX: Pronotum glabrate, shiny, scarcely punctate, ventrally with strong wrinkles; epomia strong, complete, moderately long, ending near dorsal margin of pronotum, after diverging from pronotal collar distinctly curved. Mesoscutum moderately convex, flattened posteriorly, ovoid, 1.21 × as long as wide, anteriorly densely pilose, posteriorly sparsely pilose, shiny, anteriorly densely punctate, posteriorly almost impunctate; notaulus reaching about 0.73 of mesoscutum length, deeply impressed, surface over notaulus with weak and short transverse wrinkles; scuto-scutellar groove moderately deep, without wrinkles. Subalar ridge weakly projected; epicnemial carina reaching about 0.85 of distance to subalar ridge, 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 with short transverse wrinkles; median portion of posterior transverse carina of the mesothoracic venter short and almost indistinct, slightly arched forwards. Transverse sulcus at base of propodeum very wide, about 0.81 × as long as anterior area of propodeum, asperous; metapleuron moderately punctate, without transverse wrinkles, covered with moderately dense, very short hairs; juxtacoxal carina absent. Fore tibia distinctly swollen. Mesal lobe of t4 with a distinct cluster of stout bristles. Hind coxa with moderately strong punctures separated by more than their own diameter.  
PROPODEUM: 1.11 × as long as wide, shiny, moderately pilose; anterior area sparsely punctate, with a median cluster of punctures; spiracle elongate, SWL 5.33; anterior transverse carina medially slightly arched backwards. Propodeal wrinkles strong, closely spaced, mostly incomplete and overlapped, with some disperse complete wrinkles, mostly slightly curved or somewhat sinuous; posterior transverse carina faintly suggested as a stronger wrinkle.  
WINGS: Fore wing vein 1-Rs+M very weakly sinuous, with bulla placed around its midlength; crossvein 1mcu irregular, limit between 1m-cu and 1-Rs+M clearly traceable; vein 1M+Rs anteriorly straight, posteriorly curved; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.6 of its own length; vein 2Cua 0.7 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed on midlength; cell 1+2Rs small, APH 0.67, subquadratic, about as high as wide, AWH 1.11; crossvein 3r-m partially spectral, 2r-m and 3r-m subparallel, 3r-m distinctly longer; vein 3-M almost indistinct; 4-Rs distinctly sinuous; 4-M tubular, slightly curved backwards. Hind wing vein 1-M forming distinctly obtuse angle with vein Cua; vein 2-Rs entirely tubular, apically weaker, reaching wing margin; HW1C 1.19; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.97 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 2.86; T1WW 1.81; spiracle on 0.55 of its length, distinctly prominent; median depression elongate, distinct; lateral and median posterior depressions absent; ventrolateral carina absent. T2LW 0.95; T2WW 2.04; thyridium about as long as wide, without small circular depression just behind it; T2–8 densely punctate and minutely and weakly coriarious, moderately and uniformly pilose. OST 1.69; ovipositor moderately stout, straight, basally cylindric, apically slightly depressed; dorsal valve with four moderately strong ridges; ventral valve apex with 5 teeth, widely spaced; surface anterior to first tooth rugulose.  
 Color. Head, meso- and metasoma black and whitish. Head: black; clypeus, basal 0.3 of mandible, mouthparts, supra-clypeal area, ventral spot at scape and orbital band shortly interrupted at malar space, whitish (225,214,156); f7–12 entirely white, f6 almost entirely white, f13 with small white spot. Mesosoma: black; pronotal collar, dorsal margin of pronotum, propleuron, central spot on mesoscutum, scutellar carina, scutellum except posterior 0.15, axillar carinae, tegula, subalar ridge, central mark on mesopleuron, mesosternum, dorsal division of metapleuron, metapleural triangle, transverse sulcus medially, metapleuron except small posterior spot and arc-shaped, subquadratic mark on propodeum, whitish; fore coxa whitish, fore first trochanter whitish with small orange mark; fore second trochanter, femur, tibia and t1–4 light yellow, femur dorsally with longitudinal orange stripe; fore and mid t5 blackish; mid coxa whitish, mesal face with longitudinal orange stripe on apical 0.8; mid trochanters and femur dorsally bright orange, ventrally deep yellow; mid tibia and t1 deep yellow, t2–4 dark fuscous; hind coxa anteriorly light orange, posteriorly whitish with lateral mark extending on apical 0.8; hind trochanters and femur bright orange with dorsal yellow marks; hind tibia deep yellow, hind tarsus graduall turning from deep yellow to whitish. Metasoma: black; T1 whitish, dorsally black at median 0.3, laterally at median 0.4; S1 whitish; T2–7 with posterior whitish stripe not reaching posterior margin, also extending laterally on T4–7; S2–6 whitish, with progressively smaller blackish lateral marks; T8 laterally whitish, dorsally with oblique whitish marks.   
 Male. Unknown.   
 Variation. Specimen from Suriname with fore wing 8.70 mm long; mandible whitish except apex; mesopleuron dorsad to anterior 0.4 of sternaulus and mesosternum ventrad to posterior 0.25 of sternaulus; anterior margin of metapleuron black; yellow mark on propodeum arc-shaped, not subquadratic; longitudinal stripe at fore femur blackish; ovipositor slightly upcurved.   
 Comments. More similar to M. amplithorax sp. nov., from which it can be differentiated by the central mark on mesopleuron ventrally wider (vs. distinctly S-shaped); area over sternaulus whitish (vs. black); mid and hind coxa mostly yellow, with extensive orange marks (vs. almost entirely orange); yellow mark on propodeum distinctly arc-shaped (vs. medially interrupted and forming two distinct lateral marks); scape with whitish ventral spot (vs. entirely black); mandible basally whitish (vs. entirely black); ovipositor straight, dorsal valve with four moderately strong ridges (vs. slightly upcurved, dorsal valve with five ridges); and T2 without basal yellowishs spots. Also similar to M. transversostriatus, from which it can be isolated by the absence of yellowish spots at anterior area of propodeum; mid and hind coxa mostly yellow (vs. entirely orange); yellow mark on propodeum arc-shaped; T1 short, about 0.34 × as long as T2–8 (vs. moderately long, 0.42 × as long as T2–8), and stouter, T1LW 2.86 (vs. 4.12); ovipositor longer, OST 1.69 (vs. 1.31), dorsal valve with four ridges (vs. five).   
 Biology. Unknown.   
 Etymology. From the Greek words alloios, meaning “of another kind”, and meros, meaning “thig”; in reference to the unique color pattern of the hind coxa.   
 Material examined. 2 ♀. Holotype ♀ from COLOMBIA, Bolivar, SFF Colorados, Diana, 150 m, 2–16.XII.2000, Malaise trap, EDeulufeut (AEIC). Pinned. Right fore leg apicad to first trochanter missing; otherwise in good shape.   
Paratype: 1 ♀ from SURINAME, Nickerie, baruba Kreek, km 1609, on the way to Amotopo, 17–29.IX.1980, Malaise trap, Hoogmoed & Paats, [prinzalrbos? 100 m] (RMNH).  
 Distribution. Recorded from lowlands of central Colombia and northern Suriname (Fig. 291).
