description: Messatoporus lunatus Santos, sp. nov.   
(Figs 64, 147, 340)  
 Female. Fore wing 8.25 mm. HEAD: Mandible densely covered with moderately long hairs; MLW 1.72; MWW 0.42; dorsal tooth in front view projected upwards, much longer than ventral tooth; ventral tooth triangular. MSM 0.36. Clypeus basally convex, apically abruptly flattened, centrally concave; CHW 2.66; CWW 3.21; apical area medially concave, laterally slightly projected, its margin very sharp, raised. Supra-antennal area shiny, scarcely punctate, not striate near antennal sockets, ventrally and around ocelli slightly concave, without median line. Occipital carina dorsally distinctly bell-shaped, fading out at distance shorter than basal width of mandible from the hypostomal carina. Temple and gena moderately wide, gena somewhat swollen and projected (as in Fig. 261).   
THORAX: Pronotum glabrous, shiny, impunctate, ventrally with strong wrinkles; epomia moderately strong, complete, short, ending far from dorsal margin of pronotum, after diverging from pronotal collar distinctly curved. Mesoscutum moderately convex, flattened posteriorly, subcircular, 1.13 × as long as wide, sparsely pilose, shiny, impunctate; notaulus reaching about 0.81 of mesoscutum length, moderately impressed, surface over notaulus not wrinkled; scuto-scutellar groove moderately deep, without wrinkles. Subalar ridge moderately projected; epicnemial carina reaching about 0.7 of distance to subalar ridge, irregular; sternaulus complete but weak, 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 and almost indistinct, arched backwards. Transverse sulcus at base of propodeum very wide, about 0.74 × as long as anterior area of propodeum, impunctate; metapleuron scarcely punctate, without transverse wrinkles, dorsally glabrate, ventrally sparsely 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 more than their own diameter.  
PROPODEUM: 1.13 × as long as wide, shiny, glabrate; anterior area medially almost impunctate, laterally moderately punctate; spiracle elongate, SWL 3.5; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles anteriorly faint, posteriorly strong, closely spaced, anteriorly faint at median portion, posteriorly partly complete and partly incomplete, mostly slightly curved or somewhat sinuous; posterior transverse carina entirely absent.  
WINGS: Fore wing vein 1-Rs+M distinctly sinuous, with bulla placed on basal 0.4; crossvein 1m-cu irregular, 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 0.46 of its own length; vein 2Cua 0.36 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed mostly on posterior half; cell 1+2Rs small, APH 0.77, pentagonal, about as high as wide, AWH 0.93; crossvein 3r-m fully spectral, 2r-m and 3r-m parallel, about same length; vein 3- M distinctly shorter than 2-M; 4-Rs distinctly sinuous; 4-M semi-spectral, straight. Hind wing vein 1-M forming straight angle with vein Cua; vein 2-Rs tubular, apically spectral, reaching wing margin; HW1C 1.94; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.77 of distance to posterior wing margin.  
METASOMA: First tergite short, 0.35 × as long as T2–8, strongly depressed, ventrolaterally rounded, dorsally glabrate, laterally sparsely pilose; T1LW 2.52; T1WW 2.04; spiracle on 0.52 of its length, distinctly prominent; median depression elongate, very shallow; lateral and median posterior depressions absent; ventrolateral carina absent, but traceable as limit between lateral and ventral portions. T2LW 1.12; T2WW 1.69; thyridium longer than wide, without small circular depression just behind it; T2–8 densely and finely punctate, moderately and uniformly pilose. OST 1.21; ovipositor moderately stout, straight, basally cylindric, apically slightly depressed; dorsal valve with four very weak ridges; ventral valve apex with 7 teeth, 1st, 2nd and 3th widely spaced; surface anterior to first tooth rugulose.  
 Color. Head, mesosoma and metasoma black and whitish. Head: clypeus, mandible except apex, mouthparts, malar space, supra-clypeal area except central oval spot and complete orbital band, whitish (236,225,186); white band at flagellum starting at f8. Mesosoma: black; collar and dorsal margin of pronotum connected, propleuron except dorsal marks, subcircular spot on mesoscutum, scutellar carina, scutellum, axillar carinae, postscutellum, tegula, subalar ridge, narrow and somewhat C-shaped central mark on mesopleuron, mesosternum and dorsal division of metapleuron, whitish; median 0.7 of metapleuron and arc-shaped mark on propodeum, light yellow (227,195,092); fore coxa and trochanter whitish, coxa with lateral longitudinal dark brown mark, first trochanter with dorsal dark brown mark; fore second trochanter, femur, tibia and t1–4 bright orange (217,134,062), lighter apically; fore t5 blackish; mid leg bright orange, tarsus gradually darker apically, t5 blackish; hind leg bright orange, tarsus dorsally blackish. Metasoma: black; basal 0.3 dorsally and apical 0.2 of T1, whitish; T2–8 with posterior whitish stripes; S1–6 whitish, S2–6 with progressively smaller lateral black marks.   
 Male. Fore wing 7.71–8.78 mm long. Very similar to female, except for the following: white band at flagellum restricted to dorsal face; fore tibia and tarsus ventrally whitish; mid and hind tarsus entirely blackish; hind t3–4 whitish; S2–6 black with apical whitish stripe.   
 Variation. Fore wing 8.25–9.10 mm long. Black mark at supra-clypeal area sometimes reduced or absent; mid coxa sometimes with small basal whitish mark; hind femur dark orange; apical 0.2 of hind tibia and t1–2 and t5, blackish; t3–4 sometimes whitish; all light areas either whitish or light yellow.   
 Comments. Very similar to M. dominicanus sp. nov., from which it can be differentiated by having postscutellum yellow (vs. black); yellow spot on mesopleuron distinctly C-shaped (vs. elongate, somewhat sinuous); mandible mostly whitish (vs. mostly blackish, with dorsal yellow spot); mesopleuron without wrinkles along epicnemial carina (vs. with weak longitudinal wrinkles along epicnemial carina, stronger on basal 0.3); posterior transverse carina of propodeum entirely absent (vs. distinct as very weak sublateral crests); supra-clypeal area with blackish spot at females, males usually with blackish spot (vs. without blackish spot); scape ventrally without whitish spot at females, males with weak ventral spot (vs. always with whitish spot).   
 Biology. Two specimens from Rio Piedras, Puerto Rico, were collected “on mango” (presumably at mango tree or plantation).   
 Etymology. From the Latin lunatus, meaning “shaped like a crescent moon”; in reference to the C-shaped mark at the mesopleuron.   
 Material examined. 2 ♀, 12 ♂♂. Holotype ♀ from DOMINICAN REPUBLIC, La Altagracia, Nisibon, near cacao plantation, 5–7.V.1978, flight trap, GBFairchild (FSCA). Pinned. Apical half of both antennae and right ovipositor valve missing; wings very dirty; otherwise in good shape.   
Paratypes: 2 ♂♂ from DOMINICAN REPUBLIC, La Altagracia, Nisibon, 8–10.VI.1976, Malaise trap, REWoodruff & EEGrissell; 1 ♀ from DOMINICAN REPUBLIC, Santiago, La Cumbres, 915 m, 5–17.VI.1976, Malaise trap, REWoodruff & EEGrissel. 3 ♂♂ from DOMINICAN REPUBLIC, Pedernales, 21 km N Cabo Rojo, 19–20.VI.1976, Malaise trap, REWoodruff & EEGrissel (FSCA). 3 ♂♂, same data except Baboruso, 730 m, 19–23.VII.1990, LMasner (CNCI). 1 ♀ from HAITI, Bon Repas, 3.II.1930, HLDozler. 1 ♂ from PUERTO RICO, San Juan, Rio Piedras, 30.VII.1934; 1 ♂, same data except Pt. 12, 31.VII.1934; 1 ♂, same data except Trujilo Alto, 6.VI.1934, ASMills (USNM).  
 Distribution. Recorded from the islands of Hipaniola (both Haiti and Dominican Republic) and Puerto Rico (Fig. 340). Messatoporus lunatus occurs in simpatry with the very close species M. dominicanus.
