Messatoporus bicolor Santos , sp. nov.

( Figs 91 , 307 )

Female. Fore wing 5.1 mm. HEAD: Mandible densely covered with long hairs; MLW 2.36; MWW 0.52; dorsal tooth in front view projected upwards, much longer than ventral tooth; ventral tooth triangular. MSM 0.28. Clypeus basally convex, apically abruptly flattened, centrally straight; CHW 2.17; CWW 2.36; apical area medially straight, laterally slightly projected, its margin very sharp, raised. Flagellum uniform; apex of apical flagellomere much narrower than base, distinctly tapered. Supra-antennal area shiny, with moderately dense punctation, not striate near antennal sockets, ventrally very weakly concave, medially with a distinct depression but without a distinct line. Occipital carina uniformly curved, apically very faint, meeting hypostomal carina far from mandible base. Temple and gena moderately wide, gena regular (as in Fig. 260 ).

THORAX: Pronotum sparsely pilose, shiny, mostly impunctate, scarcely punctate at dorsal corner and collar, ventrally moderately striate; epomia weak, distinct only after diverging from pronotal collar, short, ending far from dorsal margin of pronotum, after diverging from pronotal collar approximately straight. Mesoscutum moderately and uniformly convex, ovoid, 1.26 × as long as wide, densely covered with long hairs, shiny, densely punctate; notaulus reaching about 0.67 of mesoscutum length, deeply impressed, surface over notaulus not wrinkled; scutoscutellar groove deep, without wrinkles. Subalar ridge weakly projected; epicnemial carina reaching about 0.6 of distance to subalar ridge, irregular; sternaulus complete and strong, wider on posterior apex, strongly sinuous, with weak vertical wrinkles; scrobe moderately deep; mesopleural suture with weak longitudinal wrinkles along entire length. Transverse sulcus at base of propodeum moderately wide, about 0.67 × as long as anterior area of propodeum, laterally with weak longitudinal wrinkles, medially not wrinkled; metapleuron dorsally punctaterugulose, ventrally foveolate-rugulose, without transverse wrinkles, densely pilose (doubt); juxtacoxal carina represented by very short ridges. Fore tibia weakly swollen. Mesal lobe of t4 with 3–4 bristles. Hind coxa with moderately strong punctures separated by more than their own diameter.

PROPODEUM: 1.21 × as long as wide, shiny, moderately pilose; anterior area moderately punctate; spiracle elliptic, SWL 2.71; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles moderately strong, closely spaced, anteriorly irregular and ramificate, medially faint, posteriorly complete, anteriorly strongly curved, posteriorly somewhat irregular; posterior transverse carina faintly suggested as a stronger wrinkle.

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 weakly curved; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.15 of its own length; vein 2Cua 0.36 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed on midlength; cell 1+2Rs of moderate size, APH 1.45, pentagonal, distinctly higher than wide, AWH 0.79; crossvein 3r-m fully spectral, 2r-m and 3r-m subparallel, about same length; vein 3-M about as long as 2-M; 4-Rs very weakly sinuous; 4-M semi-spectral. Hind wing vein 1-M forming straight angle with vein Cua; vein 2-Rs tubular, apically spectral, reaching wing margin; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved).

METASOMA: First tergite very long, about 0.46 × as long as T2–8, strongly depressed, ventrolaterally angled, dorsally glabrate, laterally moderately pilose; T1LW 2.51; T1WW 1.62; spiracle on 0.49 of its length, distinctly prominent; median depression absent; lateral and median posterior depressions absent; ventrolateral carina absent, but traceable as limit between lateral and ventral portions. T2LW 1.28; T2WW 1.91; thyridium longer than wide, without small circular depression just behind it; T2–8 covered with small, shallow foveae, densely and uniformly pilose. OST 1.07; ovipositor moderately stout, straight, basally cylindric, apically slightly depressed; dorsal valve with five 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 dark brown, metasoma dark orange black. Head: black; mouthparts light brown; clypeus, mandible, malar space and flagellum dark brown; f9–11 entirely white; f12 dorsally, f13 with small white spot. Mesosoma: blackish; apex of metapleuron orange; legs dark brown (087,068,055); apical 0.3 of fore femur, fore and mid tibia and fore tarsus, light fuscous; mid tarsus dark fuscous; basal 0.2 of hind tibia, apical 0.5 of hind t1 and basal 0.5 of t2, whitish. Metasoma: dark orange (184,090,046), T2–8 anteriorly and laterally with sparse blackish marks.

Male. Unknown.

Comments. Differs from the other mostly blackish species of the genus by the orange metasoma and by having ovipositor moderately stout, its dorsal valve with five moderately strong ridges (vs. ovipositor slender, dorsal valve without ridges). Structurally similar to M. teutonicus , from which it can be readily distinguished by the head and mesosoma entirely blackish (vs. with many yellow marks – see Fig. 59 ); hind tibia whitish on basal 0.2 (vs. deep yellow); areolet distinctly larger, APH 1.45 (vs. 0.93), distinctly higher than wide, AWH 0.79 (vs. 1.00); and ovipositor shorter, OST 1.07, dorsal valve with five moderately strong ridges (vs. OST 1.41, dorsal valve with four weak ridges).

Biology. Unknown.

Etymology. From the latin color, added to the prefix bi-, meaning “two”; in reference to the two main body colors, black at head and mesosoma and orange at metasoma.

Material examined. Holotype ♀ from BRAZIL, Santa Catarina, Nova Teutônia , 300–500 m, 16.II.1960, FPlaumann ( CNCI). Originally glued to the pin, re-mounted on triangle point. Badly broken; right hind tarsus and left hind wing missing; and metasoma broken and re-glued to the specimen; both antenna and right hind femur and tibia broken and glued to the triangle; right hind wing folded; left mesopleuron with a perforation.

Distribution. Recorded only from the type locality, in southern Brazil ( Fig. 307 ).
