Mesosternum medially with short transverse wrinkles; median portion of posterior transverse carina of the mesothoracic venter short and almost indistinct, arched backwards. Transverse sulcus at base of propodeum very wide, about 0.95 × as long as anterior area of propodeum, impunctate; metapleuron punctate-rugulose, without transverse wrinkles, densely pilose; juxtacoxal carina absent. Fore tibia distinctly swollen. Mesal lobe of t4 with a distinct cluster of stout bristles. Hind coxa punctate-coriarious.
PROPODEUM: 1.23 × as long as wide, shiny, moderately pilose; anterior area punctate-coriarious; spiracle elongate, SWL 7.4; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles anteriorly very close and moderately strong, posteriorly stronger and more widely spaced, mostly complete, mostly slightly curved or somewhat sinuous; posterior transverse carina entirely absent.
WINGS: Fore wing vein 1-Rs+M distinctly sinuous, with bulla placed on basal 0.4; crossvein 1m-cu 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 0.44 of its own length; vein 2Cua 0.83 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed on midlength; cell 1+2Rs small, APH 0.64, pentagonal, about as high as wide, AWH 1.12; crossvein 3r-m fully spectral, 2r-m and 3r-m parallel, about same length; vein 3-M distinctly shorter than 2-M; 4- Rs distinctly sinuous; 4-M tubular, irregular. Hind wing vein 1-M forming distinctly obtuse angle with vein Cua; vein 2-Rs entirely tubular, apically weaker, reaching wing margin; HW1C 1.03; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.95 of distance to posterior wing margin.
METASOMA: First tergite moderately long, about 0.41 × as long as T2–8, somewhat depressed, ventrolaterally angled, dorsally glabrate, laterally moderately pilose; T1LW 3.91; T1WW 2.17; spiracle on 0.49 of its length, distinctly prominent; median depression elongate, distinct; median posterior depression subcircular; lateral depressions absent; ventrolateral carina absent. T2LW 1.05; T2WW 1.83; thyridium longer than wide, without small circular depression just behind it; T2–8 minutely coriarious, densely and uniformly pilose. OST 1.24; ovipositor moderately stout, straight, basally cylindric, apically slightly depressed; dorsal valve with three moderately strong ridges; ventral valve apex with 4 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth rugulose.
Color. Head, mesosoma and metasoma black and light yellow. Head: black; clypeus, mouthparts, supra-clypeal area orbital band shortly interrupted at dorsal margin of eye, light yellow (228,205,113); f7–10 entirely white, f11 mostly white, f6 with small white area apically. Mesosoma: black; collar, posterior 0.6 of dorsal margin of pronotum, propleuron laterally, subcircular spot on mesoscutum, scutellar carina, scutellum, tegula, subalar ridge, central mark on mesopleuron, mesosternum except area just ventral to sternaulus, dorsal division of metapleuron, posterior 0.8 of metapleuron except small posterior spot and lateral ovoid marks at posterior area of propodeum, light yellow; fore leg pale yellow, except posterior face of coxa, dorsal stripe at first trochanter and femur, black; fore t5 blackish; mid and hind coxae and trochanters and hind femur, deep orange (182,083,050), hind coxa with small basal light yellow mark; mid femur, mid and hind tibiae and tarsi, bright yellow (222,192,099), except dorsal and ventral blackish stripes at mid femur. Metasoma: black; T1 laterally and posterior 0.2 light yellow; S1 brownish; T2–7 with posterior and lateral light yellow stripes, T8 only with lateral stripe; S2–6 light yellow, S2–3 with small lateral brownish marks.
Male. Fore wing 9.70 mm long. Very similar to female, except by the following: basal half of the mandible yellow; f10–12 entirely white; f9 and 13–14 partially white; black area just ventrad to sternaulus very narrow; propodeal wrinkles centrally slightly more irregular; apical 0.7 of hind femur brownish; T1 laterally brown on basal 0.3.
Variation. Fore wing 10.30–12.71 mm long. Antenna with 22–25 flagellomeres; hind femur sometimes with small apical blackish mark; S4 sometimes also with lateral brownish mark; light and bright yellow areas sometimes pale yellow; S4-5 sometimes almost entirely dark brown. Specimen from Arroio Grande with cell 1+2Rs distinctly longer, APH 0.82.
Comments. Very similar to M. amplithorax sp. nov., from which it can be differentiated by having orbital band interrupted at dorsal margin of eye (vs.complete); propodeum small and somewhat rounded, distinctly shorter than thorax in lateral view (vs. large, in lateral view almost as high as thorax— Figs 68, 69 View FIGURES 66–70 ); T1 laterally yellow (vs. at least partially blackish); central mark on mesopleuron approximately rectangular (vs. somewhat S-shaped); and ovipositor dorsal valve with three moderately strong ridges (vs. five).
It is also similar to M. transversostriatus , from which it can be isolated by having anterior area of propodeum entirely black (vs. with two sublateral yellowish spots); yellow marks at posterior area ovoid (vs. distinctly wider anteriorly, Fig. 181 View FIGURES 180–188 ); mandible entirely black (vs. mostly pale yellow); central mark on mesopleuron distinctly separated from yellow spot at subalar ridge (vs. connected with spot at subalar ridge or almost so); ovipositor dorsal valve with three moderately strong ridges (vs. five); and ovipositor ventral valve with four teeth (vs. eight). It can be further differentiated from M. allomeros sp. nov. by having mid and hind coxae and hind trochanters and femur mostly bright to deep orange (vs. coxae yellow and black, trochanters and femur dark brown).
Biology. Unknown.
Etymology. From the Latin interceptus , meaning “interruption”; in reference to the interrupted orbital band, one of features that differentiates this species from other close species.
