Clypeus basally convex, apically abruptly flattened, centrally concave; CHW 2.53; CWW 2.25; apical area medially concave, laterally with distinct triangular lobes, its margin very sharp, raised. Antenna with 26 flagellomeres; flagellum uniform; apex of apical flagellomere about as wide as base, not distinctly tapered. Supraantennal area shiny, scarcely punctate, distinctly striate near antennal sockets, ventrally distinctly concave, medially with a distinct depression but without a distinct line. Occipital carina uniformly curved, fading out at distance shorter than basal width of mandible from the hypostomal carina. Temple and gena moderately wide, gena regular (as in Fig. 260 ).

THORAX: Pronotum densely pilose, shiny, punctate-recticulate, ventrally with strong wrinkles; epomia weak, distinct only after diverging from pronotal collar, short, ending far from dorsal margin of pronotum, after diverging from pronotal collar distinctly curved. Mesoscutum moderately convex, flattened posteriorly, ovoid, 1.26 × as long as wide, densely covered with short hairs, shiny, densely punctulate; notaulus reaching about 0.67 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 reaching about 0.85 of distance to subalar ridge, ventrally abruptly curved, dorsally straight; sternaulus moderately strong, wider on posterior apex, strongly sinuous, with weak vertical wrinkles; scrobe moderately deep; mesopleural suture with weak longitudinal wrinkles along entire length. 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 0.67 × as long as anterior area of propodeum, medially with very weak transverse striation; metapleuron densely punctate, ventrally also rugulose, without transverse wrinkles, densely pilose; juxtacoxal carina represented by very short ridges. Fore tibia distinctly swollen. Mesal lobe of t4 with a distinct cluster of stout bristles. Hind coxa laterally foveolate, dorsally punctate.

PROPODEUM: 1.14 × as long as wide, shiny, glabrate; anterior area densely punctate; spiracle elongate, SWL 5.45; anterior transverse carina distinctly arched backwards, its very middle raised and slightly arched forwards. Propodeal wrinkles moderately strong, very closely spaced, mostly complete, often ramificated, mostly slightly curved or somewhat sinuous, with two wrinkles medially arched backwards; posterior transverse carina entirely absent.

WINGS: Fore wing vein 1-Rs+M distinctly sinuous, with bulla placed around its midlength; crossvein 1m-cu irregular, limit between 1m-cu and 1-Rs+M more or less traceable; vein 1M+Rs anteriorly irregular, posteriorly curved; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.49 of its own length; vein 2Cua 0.79 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed on midlength; cell 1+2Rs small, APH 0.42, subquadratic, distinctly wider than high, AWH 1.69; crossvein 3r-m fully spectral, 2r-m and 3r-m parallel, 3r-m distinctly longer; vein 3-M almost indistinct; 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 straight angle with Cua; vein 2-1A reaching 0.94 of distance to posterior wing margin.

METASOMA: First tergite short, about 0.34 × as long as T2–8, somewhat depressed, ventrolaterally angled, dorsally glabrate, laterally moderately pilose; T1LW 2.72; T1WW 1.96; spiracle on 0.54 of its length, slightly prominent; median depression elongate, very shallow; median posterior depression subcircular; lateral depressions elongate, very shallow; ventrolateral carina absent, but traceable as limit between lateral and ventral portions. T2LW 1.18; T2WW 1.97; thyridium longer than wide, without small circular depression just behind it; T2–8 minutely coriarious, moderately and uniformly pilose except glabrate postero-dorsal area in T2–3. OST 1.87 Ovipositor moderately stout, slightly upcurved, basally cylindric, apically distinctly depressed; dorsal valve with five moderately strong ridges; ventral valve apex with 6 teeth, widely spaced; surface anterior to first tooth rugulose.

Color. Head and mesosoma black with bright yellow marks, metasoma mostly orange. Head: black; clypeus, mouthparts, supra-clypeal area and complete orbital band, bright yellow (237,220,108); mandible blackish but centrally somewhat lighter; f8–12 entirely white, f7 apically white. Mesosoma: black, turning to dark brown ventrally; collar, dorsal margin of propodeum, subcircular spot on mesoscutum, scutellar carina, scutellum except posterior 0.1, axillar carinae laterally, tegula, subalar ridge, central mark on mesopleuron almost reaching ventral margin, dorsal division of metapleuron, transverse sulcus medially, dorsal spot covering 0.2 of metapleuron and lateral marks on propodeum, bright yellow; fore and mid legs bright yellow, except posterior face of coxae, apical spot at first fore trochanter, basal spot at second fore and mid trochanter and dorsal stripe at fore and mid femur and first mid trochanter, blackish; fore t5 fuscous; hind coxa anteriorly dark brown, posteriorly bright yellow, with dark brown area extending posteriorly at coxa midlength; hind trochanters and femur bright orange (215,103,052); hind tibia and tarsus bright yellow, darker at tibia apex. Metasoma: bright orange; T1 black with anterior 0.4 dorsally bright yellow and posterior yellow stripe; T2 with posterior bright yellow mark, medially wider.

Variation. Female from Peru with fore wing 12.26 mm long; slightly less pilose; most dark areas somewhat reddish-dark brown; mandible mostly yellow; antenna with 28 flagellomeres; yellow marks at meso- and metapleuron and fore coxa more extensive; anterior transverse carina of propodeum not slightly arched forwards in its very middle; hind second trochanter entirely orange; T2 with narrow posterior yellow stripe.

Comments. Similar to M. euryoikos sp. nov. and M. apiopharkis sp. nov., from which it can be differentiated by the following characters: mesosternum black (vs. mostly yellow, or at least partially yellow); metapleuron mostly black (vs. mostly yellow); propodeum densely pilose (vs. scarcely punctate); anterior transverse carina distinctly arched backwards (vs. straight or arched forwards); posterior area with sublateral short subtriangular marks (vs. with oval or arc-shaped marks); and dorsal valve ovipositor of ovipositor with five ridges (vs. four). It can be additionally isolated from M. euryoikos by having mid and hind coxae yellow and black (vs. mostly orange), and from M. apiopharkis by the black postscutellum (vs. yellow).

Biology. Unknown.

Etymology. From the Greek lordos , meaning “bent backward”; in reference to the anterior transverse carina arched backwards, a rare feature in Messatoporus .

Material examined. 2 ♀. Holotype ♀ from ARGENTINA, Vila Nogues , 1.I.1966, HTownes & MTownes ( AEIC). Pinned. Apical third of right antenna and extreme tip of right antenna missing; otherwise in good shape.

Paratype: 1 ♀ from PERU, Marcapata , Plaudinger ( ZMHB) .

Distribution. Recorded from highland areas in southern Peru and northern Argentina ( Fig. 339 ).
