Clypeus basally evenly convex, apically gradually flattened, centrally straight; CHW 2.38; CWW 1.55; apical area medially straight, laterally slightly projected, its margin regular, not raised. Antenna with 28 flagellomeres; flagellum uniform; apex of apical flagellomere much narrower than base, distinctly tapered. Supra-antennal area shiny, with moderately dense punctation, distinctly striate near antennal sockets, ventrally and around ocelli slightly concave, median line distingishable only as a weakly smoother area. Occipital carina uniformly curved, fading out at distance shorter than basal width of mandible from the hypostomal carina, meeting hypostomal carina very far from mandible base. Temple and gena moderately wide, gena somewhat swollen and projected (as in Fig. 261 ).

THORAX: Pronotum sparsely pilose, shiny, densely punctate, 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 convex, flattened posteriorly, ovoid, 1.25 × as long as wide, densely covered with short hairs, shiny, densely punctate; notaulus reaching about 0.78 of mesoscutum length, moderately impressed, surface over notaulus with weak and short transverse wrinkles; scuto-scutellar groove moderately deep, with distinct longitudinal wrinkles. Subalar ridge moderately projected; epicnemial carina complete, reaching subalar ridge, distinctly sinuous; sternaulus moderately strong, wider on posterior apex, weakly sinuous, with weak vertical wrinkles; scrobe moderately deep; 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, arched backwards. Transverse sulcus at base of propodeum very wide, about 0.74 × as long as anterior area of propodeum, posteriorly with longitudinal wrinkles; metapleuron punctate-rugulose, without transverse wrinkles, densely pilose; juxtacoxal carina represented by very short ridges. Fore tibia weakly swollen. Mesal lobe of t4 with 3–4 bristles. Hind coxa laterally foveolate-areolate, dorsally rugulose.

PROPODEUM: 1.07 × as long as wide, shiny, sparsely pilose; anterior area moderately punctate; spiracle elliptic, SWL 2.5; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles moderately strong, very closely spaced, anteriorly complete, posteriorly mostly incomplete and overlapped, anteriorly strongly curved, posteriorly somewhat irregular; posterior transverse carina distinct as very weak sublateral crests.

WINGS: Fore wing vein 1-Rs+M distinctly sinuous, with bulla placed on basal 0.25; crossvein 1m-cu more or less uniformly curved, limit between 1m-cu and 1-Rs+M more or less traceable; vein 1M+Rs anteriorly straight, posteriorly curved; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.28 of its own length; vein 2Cua 0.74 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed mostly on posterior half; cell 1+2Rs small, APH 0.67, pentagonal, about as high as wide, AWH 1.09; crossvein 3r-m fully spectral, 2r-m and 3r-m distinctly convergent, about same length; vein 3-M about as long as 2-M; 4-Rs distinctly sinuous; 4-M tubular, straight. Hind wing vein 1-M forming distinctly obtuse angle with vein Cua; vein 2-Rs tubular, apically spectral, reaching wing margin; HW1C 1.39; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.9 of distance to posterior wing margin.

METASOMA: First tergite very long, about 0.53 × as long as T2–8, approximately cylindrical, ventrolaterally rounded, dorsally glabrate, laterally moderately pilose; T1LW 4.55; T1WW 1.56; spiracle on 0.52 of its length, slightly prominent; median depression absent; lateral and median posterior depressions absent; ventrolateral carina absent, but traceable as limit between lateral and ventral portions. T2LW 1.43; T2WW 2.23; thyridium longer than wide, without small circular depression just behind it; T2–8 covered with small, shallow foveae, densely and uniformly pilose. OST 0.71; ovipositor slender, straight, basally cylindric, apically slightly depressed; dorsal valve without ridges; ventral valve apex with 11 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth not rugulose.

Color. Head, mesosoma and metasoma black with whitish marks. Heas: black; clypeus, mandible except apex, mouthparts, malar space, supra-clypeal area, scape ventrally and complete orbital band, whitish (240,226,181); f9–14 entirely white. Mesosoma: black; collar and dorsal margin of pronotum connected, subcircular spot on mesoscutum, scutellar carina, scutellum, tegula, subalar ridge, central mark on mesopleuron, small spot at hypoepimeron, mesosternum except median posterior mark, dorsal division of metapleuron, metapleuron except borders and arc-shaped mark on propodeum, whitish; fore and mid coxae whitish with apical dark brown spots; first trochanters whitish with dorsal dark brown stripe; femora ventrally whitish; fore and mid second trochanters and femur dorsally, pale orange, femora with dorsal brown stripe; fore and mid tibiae pale orange, fore one with dorsal brown mark on basal 0.8; fore and mid tarsi brownish, t5 blackish; hind tibia whitish with three longitudinal stripes, anterior, median and posterior ones reaching respectively 0.6, 1.0 and 0.8 of coxa length, anterior and median stripes basally connected; area between end of posterior stripe and apical margin bright orange; first hind trochanter basally blackish, apically pale orange; second trochanter and basal mark at hind femur, pale orange; hind femur bright orange, with apical blackish mark at dorsal face; hind tibia light yellow, gradually turning to orange, then blackish on apical 0.25; basal 0.3 of t1 and t5 blackish; apical 0.7 of t1 and t2–4, whitish. Metasoma: black; T1 with anterior 0.25 dorsally and posterior 0.2 whitish; T2–8 with posterior whitish stripes (very narrow at T8); S1-6 whitish, S2–6 with lateral brownish marks.

Male. Fore wing 4.2–7.00 mm long. Very similar to female, except for the following: antenna with 24–28 flagellomeres; supra-antennal area more distinctly concave around ocelli; whitish areas on pronotum more extensive, covering about 0.4 of its surface; blackish marks at anterior sternaulus weaker; propodeal crests and posterior transverse carina more distinct; fore coxa and first trochanter entirely whitish; brownish marks at mid leg less extensive in all articles.

Variation. Fore wing 5.00– 8.57 mm long. Antenna with 25–28 flagellomeres; central mark on mesopleuron sometimes connected to small spot at hypoepimeron; vertical wrinkles at sternaulus sometimes very weak; fore femur sometimes without brownish brown mark; hind femur sometimes dark orange, sometimes dorsally mostly blackish; males with epicnemium often whitish at ventral 0.7, except small black spot; whitish tones sometimes pale yellow (220,199,131).

Comments. Very similar to the only known female of Messatoporus antennator , which was not examined. According to Kasparyan and Ruíz (2008), M. tibiator can be differentiated from the former species by having hind second trochanter orange, sometimes with dorsoposterior blackish mark (vs. black), posterior margin of mesopleuron with distinct yellowish spot dorsally to hypoepimeron (vs. black), and by having sublateral crests on propodeum absent or very weak (vs. distinct).

Biology. Unknown.
