Figs 67–71

Etymology: From the Latin voluptuosus (delightful).

Description:

Female.

Body length 5.2 mm.

Head very strongly and roundly narrowed behind eyes in dorsal view; temple 0.56× as long as eye width. Antenna short, about 0.7× as long as fore wing; flagellum filiform, with 22 segments in paratype and 23 segments in holotype; flagellomeres 3 and 4 about 1.4×, mid flagellomeres 1.2–1.3× as long as broad, subapical flagellomeres slightly elongate. Mandible with upper tooth much longer than lower tooth. Malar space half as long as basal width of mandible. Clypeus lenticular, wide, about 3.0× as broad as long, smooth, punctate in upper 0.6. Face and frons distinctly and densely punctate on granulate background. Vertex and temple finely granulate (temple almost smooth), with fine and sparse punctures. Occipital carina complete.

Mesosoma with mesoscutum distinctly and densely punctate on granulate background. Notaulus substituted by a strong wrinkle. Mesopleuron with coarse and dense punctu-res (distance between punctures mostly shorter than one diameter of puncture), more or less smooth between punctures centrally and finely granulate peripherally. Foveate groove in anterior 0.6 of mesopleuron, not reaching anterior margin of mesopleuron, strongly oblique, deep, with strong transverse wrinkles. Propodeal spiracle rather big, separated from pleural carina by 1.5–2.0 diameters of spiracle. Propodeum with basal keel (indistinct in holotype and weak in paratype) half as long as apical area, with short longitudinal wrinkles extending anteriorly from transverse carina; dorsolateral area granulate, distinctly and densely punctate; apical area widely rounded anteriorly, flat, uneven, partly granulate, impunctate, with fine transverse wrinkles; apical longitudinal carinae strong, reaching transverse carina anteriorly.

Fore wing length 3.8 mm. First abscissa of radius straight, longer than width of pterostigma. Metacarp not reaching apex of fore wing. Second recurrent vein postfurcal. Intercubitus distinctly longer than abscissa of cubitus between intercubitus and second recurrent vein. Hind wing with nervellus slightly reclivous.

Legs slender. Hind femur 4.5× as long as broad and 0.8× as long as tibia. Spurs of hind tibia slightly curved at apex. Tarsal claws not pectinate.

Tergite 1 of metasoma smooth, 3.5× as long as broad posteriorly, with small, isolated glymma and short, shallow groove before glymma, with petiole round or slightly trapeziform in cross-section. Second tergite 1.37–1.39× as long as broad anteriorly; thyridial depression 1.5× as long as broad. Ovipositor long, upcurved, with very shallow dorsal subapical depression; sheath 2.6× as long as hind tibia and 2.8× as long as first tergite.

Head and mesosoma black.Antenna with scape and pedicel yellow, flagellum brownish yellow basally to yellow apically, with apical 4 or 5 flagellomeres black. Clypeus brownish yellow in lower 0.3 and brownish in upper 0.3. Palpi, mandible (except for blackish teeth), tegula and legs yellowish. Pterostigma brown. Metasoma behind tergite 1 yellow to brownish yellow, dorsal sides of tergites 3+ brown anteriorly.

Male. Unknown.
