T2LW 1.33; T2WW 1.91; thyridium longer than wide, with small circular depression just behind it; T2–8 minutely and very weakly coriarious, laterally moderately pilose, dorsally T2–3 and 8 glabrate, T4–7 sparsely to moderately pilose. OST 1.72; ovipositor moderately stout, straight, basally cylindric, apically slightly depressed; dorsal valve with four moderately strong ridges; ventral valve apex with 6 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth rugulose.

Color. Head black, mesosoma black and yellow, metasoma orange. Head: black; clypeus, small mark at mandible midlength, mouthparts, supra-clypeal area and complete orbital band, whitish (241, 228, 184); f8–9 entirely white, f7 and f10 almost entirely white, f11 dorsally white. Mesosoma: black; narrow stripes at collar and dorsal margin of pronotum, propleuron, large subcircular spot on mesoscutum, scutellar carina, scutellum, axillar carina, tegula, subalar ridge, central mark on mesopleuron, spots at lateral mesosternum, dorsal division of metapleuron, metapleuron except anterior and ventral mergins and ovoid lateral marks on propodeum, whitish; anterior face of fore coxa, anterior mark at mid coxa, posterior mark at hind coxa, ventral face of fore first trochanter, ventral face of fore and mid femur, fore and mid tibia and tarsi except blackish t5, whitish; most of mid tibia and trochanters except sparse black marks, hind coxa, trochanters and femur, orange (222, 118, 046); hind tibia basally light yellow, slightly darker apically; hind tarsus whitish. Metasoma: orange; T1 black with posterior whitish stripe; anterior margin of T2 blackish; metasomal sternites with posterior whitish stripe, weaker towards apical sternites.

Male. Fore wing 6.22–9.42 mm long. Differs from female by the following characters: mandible whitish (except apex); scape ventrally always with whitish spot; pronotum smaller, its dorsal margin anteriorly slightly concave; mesoscutum more distinctly convex; scrobe less distinctly concave; central portion of mesopleuron slightly more projected, somewhat swollen; central mark reaching posterior margin of mesopleuron and connected with whitish area of mesosternum; mesosternum almost entirely whitish; fore coxa entirely whitish; dark areas on femora pale brown, sometimes almost fading; mid coxa and trochanters whitish; hind coxa with large longitudinal stripe anteriorly to stripe pale orange, posteriorly whitish; T1–7 anteriorly blackish to brownish, with posterior whitish stripe which is progressively wider toward posterior tergites.

Considerably different from female in color, particularly because of the striped metasoma and mid and hind coxae not orange, but recognizable by the propodeum pattern and other similarities.

Variation. Fore wing 8.39–12.07 mm long. Whitish spots covering 0–60% of mandible surface; scape sometimes with whitish ventral spot; antenna sometimes with 22–23 flagellomeres; pronotal wrinkles sometimes weak; central mark on mesopleuron sometimes connected with subalar ridge whitish spot, sometimes connected with mesosternum marks (surface over sternaulus whitish); sternaulus with vestigial to distinct vertical wrinkles; white marks at fore coxa covering 0–80% of its surface; mid and hind coxa either with or without black marks; second hind trochanter ventrally sometimes blackish; T1 sometimes fuscous, sometimes with anterior 0.1-0.3 whitish; in specimen from Caxiuanã medially orange instead of black; anterior margin of T2 sometimes not blackish; one specimen from Rio Claro and one from Morro Redondo with T2 laterally blackish, centrally brownish, with posterior yellow stripe; ovipositor sometimes slightly upcurved; one male from Ipiaú with hind second trochanter almost entirely blackish, hind femur bright orange apically marked with blackish, apical 0.2 of hind tibia and basal 0.5 of t1 blackish. Specimen from Morro Redondo with pronotum smaller and anteriorly concave, similar to male specimens, and propodeal wrinkles more curved backwards. One male specimen from Caruaru with hind coxa yellow, with wide black lateral stripe, ventrally orangish, and T1 basally dark brown. Orange tones varying from bright to deep (197,096,041); whitish tones varying from sometimes yellow (236,215,119) or buff (217,191,115).

Comments. Very close to M. apiopharkis sp. nov., from which it can be differentiated by having mid and hind coxae mostly orange (vs. yellow and black); posterior area of propodeum with two ovoid longitudinal yellow marks (vs. with one arc-shaped mark); postscutellum black (vs. yellow); flagellum with uniform width (vs. flattened and widened at subapical 0.3); apical area of clypeus medially concave (vs. straight); epomia and wrinkles on pronotum weak (vs. strong); propodeal wrinkles closely spaced (vs. moderately widely spaced); and ovipositor ventral valve with six teeth (vs. nine). It is also similar to M. lordos sp. nov., which differs from M. euryoikos in the yellow and black coxae; posterior marks on propodeum short and sub-triangular ( Fig. 184 ); mesosternum black (vs. at least partially yellow); and propodeum densely punctate (vs. scarcely punctate), with anterior transverse carina medially distinctly arched forwards (vs. straight).

Male specimens of M. amplithorax sp. nov. can be mistaken as males of M. euryoikos , because the mid and hind leg color pattern are much more similar to the female of M. euryoikos , with mid and hind coxae and trochanters and hind femur bright orange. To correctly identify the males of M. euryoikos , the description provided above must be considered; they can also be readily recognized as such by the posterior marks on propodeum, very similar to those of females (vs. much wider on midlength in M. amplithorax ); and postscutellum pale yellow to whitish (vs. black).

Biology. Unknown.

Etymology. From the Greek words eury, meaning “broad”, and oikos, meaning “house”; in reference to its wide geographic record.

Distribution. Messatoporus euryoikos is a very widespread species, occurring from Panama to southern Brazil ( Fig. 325 ). The collection sites encompass many different environments and climates, from subtropical (southern Brazil) to equatorial (Amazon Basin and Panama), from semi-arid (northeastern Brazil) to very humid (Amazon Basin). That indicates a large environmental flexibility, and suggests that M. euryoikos may occur throughout all South America.
