Messatoporus longicaudis Santos , sp. nov.
( Figs 38 View FIGURES 36–40 , 166 View FIGURES 162–170 , 260, 269 View FIGURES 260–271. 260–261 , 337 View FIGURES 337–344 )
Female. Fore wing 9.09 mm. HEAD: Mandible densely covered with long hairs; MLW 2.18; MWW 0.37; dorsal tooth in front view projected upwards, much longer than ventral tooth; ventral tooth triangular. MSM 0.21. Clypeus almost entirely flattened, centrally straight; CHW 2.55; CWW 1.88; apical area medially concave, laterally slightly projected, its margin very sharp, raised. Antenna with 27 flagellomeres; flagellum uniform; apex of apical flagellomere much narrower than base, distinctly tapered. Supra-antennal area shiny, scarcely punctate, not striate near antennal sockets, ventrally distinctly concave, dorsally with very weak median line, ventrally fading. Occipital carina uniformly curved, fading out at distance about as long as basal width of mandible from the hypostomal carina, meeting hypostomal carina far from mandible base. Temple and gena narrow, gena regular (as in Fig. 260 View FIGURES 260–271. 260–261 ).
THORAX: Pronotum glabrous, shiny, impunctate, not distinctly wrinkled; epomia very weak, distinct only after diverging from pronotal collar, short, ending far from dorsal margin of pronotum, after diverging from pronotal collar approximately straight. Mesoscutum strongly and uniformly convex, subcircular, 1.22 × as long as wide, sparsely pilose, shiny, impunctate; notaulus reaching about 0.68 of mesoscutum length, moderately impressed, surface over notaulus not wrinkled; scuto-scutellar groove moderately deep, without wrinkles. Subalar ridge weakly projected; epicnemial carina reaching about 0.85 of distance to subalar ridge, distinctly sinuous; sternaulus complete but weak, strongly sinuous, smooth; scrobe very shallow; mesopleural suture without wrinkles. Mesosternum medially without transverse wrinkles or depressions; median portion of posterior transverse carina of the mesothoracic venter short and almost indistinct, arched backwards. Transverse sulcus at base of propodeum moderately wide, about 0.63 × as long as anterior area of propodeum, very weakly rugulose; metapleuron moderately punctate, with vestigial wrinkles, dorsally sparsely pilose, ventrally moderately pilose; juxtacoxal carina absent. Fore tibia not 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 (, posteriorly weakly rugulose).
PROPODEUM: 1.24 × as long as wide, shiny, sparsely pilose; anterior area scarcely punctate, medially strigulate; spiracle elliptic, SWL 2.5; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles anteriorly very close and moderately strong, posteriorly stronger and more widely spaced, very closely spaced, mostly incomplete and overlapped, with some disperse complete wrinkles, mostly slightly curved or somewhat sinuous; 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 clearly traceable; vein 1M+Rs anteriorly straight, posteriorly curved; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.51 of its own length; vein 2Cua 0.32 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed on midlength; cell 1+2Rs of moderate size, APH 0.84, pentagonal, distinctly wider than high, AWH 1.02; crossvein 3r-m fully spectral, 2r-m and 3r-m parallel, about same length; vein 3-M distinctly longer than 2-M; 4-Rs distinctly sinuous; 4-M tubular, irregular. Hind wing vein 1-M forming distinctly obtuse angle with vein Cua; vein 2-Rs entirely tubular, apically weaker, reaching wing margin; HW1C 0.96; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.86 of distance to posterior wing margin.
METASOMA: First tergite moderately long, about 0.37 × as long as T2–8, somewhat depressed, ventrolaterally rounded, dorsally glabrate, laterally moderately pilose; T1LW 3.69; T1WW 1.97; spiracle on 0.47 of its length, distinctly prominent; median depression elongate, very shallow; lateral and median posterior depressions absent; ventrolateral carina absent. T2LW 1.61; T2WW 2.16; thyridium longer than wide, without small circular depression just behind it; T2–8 minutely and very weakly coriarious, densely and uniformly pilose. OST 2.5; ovipositor moderately stout, strongly upcurved, basally cylindric, apically distinctly depressed; dorsal valve with four weak ridges; ventral valve apex with 9 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth rugulose.
Color. Head black; meso and metasoma orange (210,119,052). Head: black; f8–13 entirely white, 7 and 14 partially white; scape ventrally, clypeus, mandible except apex, palpi, supra-clypeal area, orbital band broadly interrupted at temple, whitish. Mesosoma: orange; mesoscutum centrally with weak blackish mark; fore and mid legs lighter than thorax, apical tarsomere dark fuscous; hind tibia yellow; hind tarsus whitish. Mesosoma: orange; T3-8 anteriorly dark fuscous.
Male. Fore wing 6.75–6.96 mm long. Very similar to female, except for the following: antenna with 26 flagellomeres; pronotum, central lobe of mesoscutum and anterior area of propodeum with brownish marks; apical 0.25 of hind tibia and basal 0.7 of t1, dark brown; T1–8 dark fuscous, T1–2 anteriorly dark brown.
Variation. Fore wing 8.80–9.53 mm long. Paratype females with mesosoma bright orange, without blackish marks at mesoscutum; scrobe less distinctly concave; propodeum slightly less elongate; fore and mid tibiae and tarsi yellow except apical tarsomere; metasoma entirely dark fuscous except posterior 0.2, orange.
Comments. Readily differentiated from all other species of Messatoporus by the very long ovipositor, 2.50 × as long as hind tibia, mesoscutum very strongly convex, ventral portion of epicnemium strongly concave and fore tibia not distinctly swollen. It can be additionally isolated from the similar M. aurantius sp. nov., by the propodeum in lateral view somewhat flattened (vs. rounded, subspherical), with moderately closely spaced transverse wrinkles (vs. very closely spaced), fore wing crossveins 2r-m and 3r-m distinctly convergent (vs subparallel) and vein 3-M distinctly longer than 2-M (vs. two veins about the same size).
Biology. Unknown.
Etymology. From the Latin words longus, meaning “long”, and cauda, meaning “tail”; in reference to its very long ovipositor.
