description: Messatoporus bennetti Santos, sp. nov.   
(Figs 96, 150, 221, 286, 306)  
 Female. Fore wing 11.43 mm. HEAD: Mandible densely covered with long hairs; MLW 1.98; MWW 0.41; dorsal tooth in front view projected upwards, much longer than ventral tooth; ventral tooth triangular. MSM 0.26. Clypeus basally convex, apically abruptly flattened, centrally concave; CHW 2.22; CWW 1.79; apical area medially concave, laterally with distinct triangular lobes, its margin very sharp, raised. Supra-antennal area shiny, with moderately dense punctation, not striate near antennal sockets, ventrally and around ocelli slightly concave, medially with a distinct depression but without a distinct line. Occipital carina uniformly curved, fading out at distance about as long as basal width of mandible from the hypostomal carina. Temple and gena moderately wide, gena regular (as in Fig. 260).   
THORAX: Pronotum moderately pilose, mat, densely punctate, with moderate striation along posterior margin and collar; 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, 1.21 × as long as wide, densely covered with short hairs, shiny, densely punctate; notaulus reaching about 0.65 of mesoscutum length, moderately impressed, surface over notaulus with weak and short transverse wrinkles; scuto-scutellar groove moderately deep, without wrinkles. Subalar ridge weakly projected; epicnemial carina reaching only 0.2 of distance to subalar ridge, after that represented by a wrinkled sulcus; sternaulus moderately strong, wider on posterior apex, strongly sinuous, smooth; scrobe very shallow; 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 moderately wide, about 0.63 × as long as anterior area of propodeum, impunctate; metapleuron densely punctate, 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 with moderately strong punctures separated by about their own diameter.  
PROPODEUM: 1.13 × as long as wide, shiny, densely pilose; anterior area moderately punctate; spiracle elongate, SWL 5.27; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles moderately strong, closely spaced, anteriorly faint at median portion, posteriorly partly complete and partly incomplete, distinctly curved 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 clearly traceable; vein 1M+Rs anteriorly straight, posteriorly weakly curved; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.563 of its own length; vein 2Cua 0.73 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed on midlength; cell 1+2Rs of moderate size, APH 0.85, pentagonal, distinctly wider than high, AWH 1.21; crossvein 3r-m fully spectral, 2r-m and 3r-m subparallel, about same length; vein 3-M distinctly shorter than 2-M; 4-Rs distinctly sinuous (and strong); 4-M tubular, straight. Hind wing vein 1-M forming distinctly obtuse angle with vein Cua; vein 2-Rs entirely tubular, apically weaker, reaching wing margin; HW1C 2.15; vein Cub distinctly convex on posterior half, forming straight angle with Cua; vein 2- 1A reaching 0.96 of distance to posterior wing margin.  
METASOMA: First tergite short, about 0.35 × as long as T2–8, somewhat depressed, ventrolaterally angled, dorsally glabrate, laterally moderately pilose; T1LW 3.2; T1WW 1.89; spiracle on 0.51 of its length, distinctly prominent; median depression elongate, distinct; lateral and median posterior depressions absent; ventrolateral carina absent, but traceable as limit between lateral and ventral portions. T2LW 1.17; T2WW 2.12; thyridium longer than wide, without small circular depression just behind it; T2–8 minutely and very weakly coriarious, densely and uniformly pilose. OST 1.68; ovipositor moderately stout, straight, 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, mesosoma and metasoma black with pale yellow marks. Head: black; clypeus except margins and apical central mark, mouthparts and orbital band shortly interrupted at malar space and dorsal margin of eye, pale yellow (233,212,123); white band at flagellum starting at f7, partially white. Mesosoma: black; collar, short dash at dorsal margin of pronotum, subcircular spot on mesoscutum, scutellar carina, scutellum except apical margin, tegula two separate marks on mesopleuron, dorsal division of metapleuron, transverse sulcus centrally, central mark covering 0.6 of metapleuron and lateral marks on propodeum, pale yellow; fore leg pale yellow except most of fore coxa posteriorly, dorsal stripe on basal 0.6 of femur and t5, black; second fore trochanter and femur dorsally light orange; mid leg pale yellow except posterior face of coxa and dorsal stripe at trochanters and femur, black; hind tibia anteriorly black, posteriorly yellow with a black mark which is connected to the anterior black portion; hind trochanters, femur and apical 0.5 of tibia black; basal 0.5 of tibia and hind tarsus, pale yellow. Metasoma: black; anterior 0.4 of T1 pale yellow; T1–7 with posterior pale yellow stripes, progressively wider at posterior tergites; S1 black; S2–7 pale yellow except anterior stripe at T2–3.   
 Male. Unknown.   
 Comments. Similar in color pattern to M. bimaculatus sp. nov. and M. unimaculatus sp. nov., from which it can be differentiated mainly by its generally larger size, fore wing 11.43 mm (vs. 5.94–8.25 mm long); orbital band widely interrupted at dorsal margin of eye (vs. complete); ovipositor much longer, OST 1.68 (vs. 0.66–0.84), moderately stout, dorsal valve with five moderately strong ridges (vs. slender, dorsal valve without ridges); T7–8 distinctly longer than T5–8 (vs. about as long as T5–6); and hind femur entirely black (vs. mostly orange).   
 Biology. Unknown.   
 Etymology. Named after the hymenopterist Andrew Bennett (CNCI); in acknowledgement of his valuable help in many steps of this work.   
 Material examined. Holotype ♀ from COSTA RICA, Puntarenas, Monteverde, 23.VIII–5.IX.1996, CCondy (CNCI). Mounted on triangle point. Right antenna, apical two thirds of left antenna and right mid tarsus missing; otherwise in good shape.   
 Distribution. Recorded only from the type locality, in Costa Rica (Fig. 306).
