Diaparsis (Diaparsis) kolyadai sp. n.

Figs 28–33

Etymology: Named in honour of the expert on Proctotrupoidea, who has collected a large number of Hymenoptera in South Africa, Viktor Kolyada (Paleontological Institute of the Russian Academy of Sciences, Moscow, Russia).

Diagnosis: The new species is very similar to D. vulgaris sp. n., but differs by having a small clypeus and longer malar space.

Description:

Female.

Body length 4.0 mm.

Head rounded behind eyes in dorsal view; temple 0.72× as long as eye width. Flagellum of antenna slightly clavate at apex, with 19–20 segments; sub­basal flagellomeres about 1.8× and subapical flagellomeres 1.2–1.3× as long as broad. Mandible slender, rather strongly tapered apically, with upper tooth distinctly longer than lower tooth. Malar space 0.9–1.0× as long as basal width of mandible. Clypeus 2.1× as broad as long, slightly convex in lateral view, sparsely punctate and very finely coriaceous in upper 0.6, smooth in lower 0.4. Face and frons finely and densely punctate on granulate background. Vertex finely granulate and very indistinctly punctate. Temple finely granulate, almost smooth centrally, with fine but distinct punctures. Occipital carina complete.

Mesosoma with mesoscutum finely and densely punctate on granulate background. Notaulus with short wrinkle. Mesopleuron granulate (very finely granulate centrally), with rather distinct dense punctures (punctures mostly indistinct peripherally). Foveate groove in anterior half of mesopleuron, moderately deep to rather shallow, strongly ob-lique, with transverse wrinkles. Propodeal spiracle small, separated from pleural carina usually by 1.5–2.0 (3.0 in one paratype) diameters of spiracle. Propodeum with basal keel 0.37× as long as apical area; dorsolateral area granulate, with very fine (sometimes indistinct) punctures. Apical area flat, pointed or roundly pointed anteriorly, granulate, impunctate; apical longitudinal carinae very weak anteriorly, usually not reaching transverse carina.

Fore wing length 3.25 mm. First abscissa of radius straight, longer than width of pterostigma. Metacarp almost reaching apex of fore wing. Second recurrent vein postfurcal. Intercubitus somewhat longer than abscissa of cubitus between intercubitus and second recurrent vein (except one paratype with intercubitus slightly shorter). Hind wing with nervellus slightly reclivous.

Legs slender. Hind femur 4.75× as long as broad and 0.88× as long as tibia. Spurs of hind tibia slightly curved at apex. Tarsal claws not pectinate, strongly curved.

Tergite 1 of metasoma very slender, 4.5× as long as broad posteriorly, smooth, petiole round in cross-section, with small glymma, short and shallow groove before glymma and more or less distinct vestige of groove from glymma to ventral part of postpetiole. Second tergite 1.75× as long as broad anteriorly; thyridial depression distinct, about 1.5× as long as broad. Ovipositor slender, rather strongly upcurved, with shallow, dorsal subapical depression; sheath about 2.3× as long as hind tibia and first tergite.

Head, mesosoma and tergite 1 of metasoma black; pronotum anteriorly yellowish red, upper part of mesopleuron sometimes reddish brown. Scape and pedicel of antenna, palpi, mandible (except for blackish teeth), lower 0.3 of clypeus and tegula brownish yellow. Flagellum brownish basally to fuscous apically. Pterostigma brown. Legs yellow-brown to brown. Metasoma behind tergite 1 predominantly brown, yellowish ventrally.

Male. Unknown.
