Clypeus basally convex, apically abruptly flattened, centrally concave; CHW 2.21; CWW 1.56; apical area medially concave, laterally slightly projected, its margin very sharp, raised. Antenna with 28 flagellomeres; flagellum uniform; apex of apical flagellomere much narrower than base, distinctly tapered. Supra-antennal area shiny, laterally coriarious, centrally colliculate, weakly rugulose near antennal sockets, ventrally distinctly concave, median line distingishable only as a weakly smoother area. Occipital carina uniformly curved, apically weak, meeting hypostomal carina far from mandible base. Temple and gena moderately wide, gena regular (as in Fig. 260 ).

THORAX: Pronotum centrally glabrate, moderately pilose at dorsal margin and pronotal collar, shiny, rugulose-colliculate, ventrally with strong wrinkles; epomia moderately strong, complete, short, ending far from dorsal margin of pronotum, after diverging from pronotal collar approximately straight. Mesoscutum moderately and uniformly convex, ovoid, 1.35 × as long as wide, anteriorly densely pilose, posteriorly sparsely pilose, mat, punctate-coriarious; notaulus reaching about 0.78 of mesoscutum length, moderately impressed, surface over notaulus with weak and short transverse wrinkles; scuto-scutellar groove deep, with vestigial longitudinal wrinkles. Subalar ridge moderately projected; epicnemial carina complete, reaching subalar ridge, distinctly sinuous; sternaulus complete and strong, wider on posterior apex, strongly sinuous, with weak vertical wrinkles; scrobe moderately deep; 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, straight. Transverse sulcus at base of propodeum moderately wide, about 0.57 × as long as anterior area of propodeum, laterally with weak longitudinal wrinkles, medially not wrinkled; metapleuron minutely rugulose, without transverse wrinkles, dorsally sparsely pilose, ventrally moderately pilose; juxtacoxal carina represented by very short ridges. Fore tibia weakly swollen. Mesal lobe of t4 with 3–4 bristles. Hind coxa rugulose-coriarious.

PROPODEUM: 1.08 × as long as wide, shiny, moderately pilose; anterior area almost impunctate; spiracle elliptic, SWL 2.42; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles anteriorly weak, posteriorly strong, closely spaced, mostly complete, anteriorly distinctly arched forwards, posteriorly distinctly arched backwards; posterior transverse carina distinct as moderately strong crests.

WINGS: Fore wing vein 1-Rs+M very weakly sinuous; crossvein 1m-cu more or less uniformly curved, totally continuous with 1-Rs+M; vein 1M+Rs entirely irregular; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.39 of its own length; vein 2Cua 0.61 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed on midlength; cell 1+2Rs of moderate size, APH 0.83, pentagonal, about as high as wide, AWH 0.98; 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 very weakly sinuous; 4- M semi-spectral, slightly curved backwards. Hind wing vein 1-M forming distinctly obtuse angle with vein Cua; vein 2-Rs tubular, apically spectral, reaching wing margin; HW1C 1.44; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.96 of distance to posterior wing margin.

METASOMA: First tergite moderately long, about 0.4 × as long as T2–8, approximately cylindrical, ventrolaterally angled, uniformly, densely pilose; T1LW 4.49; T1WW 1.36; spiracle on 0.51 of its length, slightly prominent; median depression absent; lateral and median posterior depressions absent; ventrolateral carina absent. T2LW 1.5; T2WW 2.23; thyridium much longer than wide, without small circular depression just behind it; T2–8 minutely coriarious, densely and uniformly pilose. OST 0.68; ovipositor slender, straight, basally cylindric, apically slightly depressed; dorsal valve without ridges; ventral valve apex with 8 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth not rugulose.

Color. Head black, mesosoma black and brownish orange, metasoma dark brown and pale yellow. Head: black; labrum, dorsal mark at mandible, dorsal spot at supra-clypeal area and weak orbital band distinct only at supraclypeal area and part of gena, pale yellow (227,216,154); palpi and scape ferruginous; pedicel dark brown; flagellum basally ferruginous, gradually turning to blackish towards apex; f10–12 dorsally whitish. Mesosoma: black; small marks at pronotal collar, dorsal margin of pronotum, lateral scutellum and subalar ridge, whitish (247,238,182); dorsal division of metapleuron, posterior 0.3 of metapleuron and somewhat arc-shaped mark on propodeum, reddish brown (158,078,053); propodeal crests yellowish; fore coxa dark brown; fore trochanters, femur and tibia pale yellow; first trochanter and femur dorsally with longitudinal brownish stripes; fore tibia with dorsal and ventral brownish stripes; fore tarsus gradually turning from pale yellow basally to blackish at t5; mid coxa brownish orange with sparse brownish marks; mid trochanters ventrally light orange, dorsally brownish; mid femur light orange, dorsally brownish; mid tibia pale yellow, dorsally marked with blackish; mid t1–4 brown, t5 blackish; hind coxa dark orange, with small apical blackish mark; hind trochanters and extreme base and apex of femur, dark brown; hind femur dark orange; hind tibia and tarsus blackish, tibia with sub-basal whitish mark. Metasoma: blackish; T1–7 and S2–6 with posterior pale yellow stripes; T1 dorsally pale yellow on basal 0.25.

Male. Unknown.

Comments. More similar to M. andinus sp. nov., from which it can be differentiated by having orbital band almost entirely absent (vs. complete); hind coxa reddish orange with apical blackish spot (vs. black or dark brown, with posterior yellow mark); propodeal spiracle elliptic, SWL 2.42 (vs. elongate, SWL 3.64); postscutellum black (vs. yellow); anterior area of propodeum almost impunctate (vs. asperous and densely puncutlate); epomia complete, approximately straight (vs. distinct only after diverging from collar, distinctly curved); occipital carina meeting hypostomal carina, tough apically weak (vs. not meeting hypostomal carina); scuto-scutellar deep, with vestigial wrinkles (vs. shallow, without wrinkles); and ovipositor ventral valve with eight teeth (vs. eleven).

Biology. Unknown.

Etymology. Latinized form of Matucana , in reference to its type locality.
