Messatoporus badius Santos , sp. nov.

( Figs 90 , 164 , 305 )

Female. Fore wing 9.5 mm. HEAD: Mandible densely covered with long hairs; MLW 2.03; MWW 0.37; dorsal tooth in front view projected upwards, much longer than ventral tooth; ventral tooth somewhat rhomboid. MSM 0.3. Clypeus basally convex, apically abruptly flattened, centrally concave; CHW 2.43; CWW 2.5; apical area medially concave, laterally with distinct triangular lobes, its margin very sharp, raised. Antenna with 29 flagellomeres; flagellum uniform; apex of apical flagellomere much narrower than base, distinctly tapered. Supraantennal area mat, with moderately dense punctation, distinctly striate near antennal sockets, ventrally and around ocelli slightly concave, without median line. Occipital carina uniformly curved, fading out at distance shorter than basal width of mandible from the hypostomal carina. Temple and gena narrow, gena regular (as in Fig. 260 ).

THORAX: Pronotum moderately pilose, mat, minutely punctulate or punctate-rugulose, with moderate striation along posterior margin and collar; epomia almost indistinct, distinct only after diverging from pronotal collar, short, ending far from dorsal margin of pronotum, after diverging from pronotal collar distinctly curved. Mesoscutum moderately and uniformly convex, ovoid, 1.27 × as long as wide, densely covered with short hairs, mat, densely punctulate; notaulus reaching about 0.77 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 reaching about 0.85 of distance to subalar ridge, more or less uniformly curved; sternaulus complete and strong, wider on posterior apex, strongly sinuous, with weak vertical wrinkles; 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, distinctly arched forwards. Transverse sulcus at base of propodeum very wide, about 0.82 × as long as anterior area of propodeum, with strong longitudinal wrinkles; metapleuron punctate-rugulose, without transverse wrinkles, dorsally moderately pilose, ventrally densely pilose; juxtacoxal carina represented by very short ridges. Fore tibia weakly swollen. Mesal lobe of t4 with a distinct cluster of stout bristles. Hind coxa punctate-coriarious.

PROPODEUM: 1.07 × as long as wide, mat, densely pilose; anterior area shallowly foveolate; spiracle elongate, SWL 4.00; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles moderately strong, closely spaced, ramificated and irregular, rugulose anteriorly at lateral portions and posteriorly at median portion; posterior transverse carina faintly suggested as a stronger wrinkle, sublaterally forming weak sublateral crests.

WINGS: Fore wing vein 1-Rs+M distinctly sinuous, with bulla placed on basal 0.4; crossvein 1m-cu more or less uniformly curved, limit between 1m-cu and 1-Rs+M clearly traceable; vein 1M+Rs uniformly curved; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.44 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 small, APH 0.75, pentagonal, about as high as wide, AWH 0.91; crossvein 3r-m fully spectral, 2r-m and 3r-m distinctly convergent, 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 1.38; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.91 of distance to posterior wing margin.

METASOMA: First tergite moderately long, about 0.38 × as long as T2–8, approximately cylindrical, ventrolaterally angled, uniformly, densely pilose; T1LW 4.8; T1WW 1.46; spiracle on 0.48 of its length, slightly prominent; median depression absent; median posterior depression absent; lateral depressions elongate, very shallow; ventrolateral carina very weak. T2LW 1.69; T2WW 2.83; thyridium much longer than wide, without small circular depression just behind it; T2–8 densely punctate and minutely and weakly coriarious, densely and uniformly pilose. OST 1.04; ovipositor slender, slightly sinuous, basally cylindric, apically slightly depressed; dorsal valve without ridges; ventral valve apex with 10 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth not rugulose.

Color. Head, meso- and metasoma reddish brown. Head: reddish brown (151,069,049); dorsal spot at supraclypeal area and orbital band widely interrupted at malar space and dorsal margin of eye, yellow (217,140,060); apical 0.5 of mandible and flagellum blackish; f5–13 whitish yellow, f4 and f14 with yellowish spots. Mesosoma: reddish brown; fore coxa, fore and mid trochanters and femur light orange, fore and mid tibia deep yellow; fore and mid t1–2 basally orange, apically dark fuscous, t3–4 dark fuscous, t5 blackish; hind tibia basally deep yellow, gradually turning to blackish on apical 0.25; basal 0.25 of t1 and t5 blackish; apical 0.75 of t1 and t2–4 whitish yellow. Metasoma: reddish brown; anterior 0.4 of T2–8 dark brown; S2–6 dark brown, with narrow posterior whitish stripe.

Male. Unknown.

Comments. Similar to M. paradoxus sp. nov., from which it can be differentiated by having mesosoma and legs uniformly reddish brown (vs. mesosoma mostly mid brown, with mesosternum and coxae dark brown); T4–7 anteriorly dark brown, posteriorly brownish orange (vs. entirely bright orange); propodeal wrinkles distinct and moderately strong (vs. vestigial, most of posterior area areolate-rugulose); ovipositor dorsal valve without ridges (vs. with three very weak ridges); surface anterior to first tooth of ventral valve not rugulose (vs. rugulose) and epomia after diverging from collar distinctly curved (vs. approximately straight).

Biology. Unknown.

Etymology. From the latin badius , meaning “reddish-brown”; in reference to its body color.

Material examined. Holotype ♀ from GUATEMALA, Zacapa, San Lorenzo , 2200 m, XI.1986, M. Sharkey ( AEIC). Pinned. Apical half of left antenna broken and re-glued to specimen; otherwise in good shape.

Distribution. Recorded only from the type locality, in highlands of Guatemala ( Fig. 305 ).
