Diaparsis (Diaparsis) vulgaris sp. n.

Figs 72–76 View Figs 72–76

Etymology: From the Latin vulgaris (usual, common), because it is the most abundant species of Diaparsis in the Afrotropical region.

Diagnosis: Differs from Afrotropical congeners in having the following combination of features: long ovipositor, finely and sparsely punctate mesopleuron and dorsolateral area of propodeum, broad clypeus and clavate flagellum of female with 20–23 segments.



Body length 4.8 mm.

Head rounded behind eyes in dorsal view; temple 0.7× as long as eye width. Flagellum of antenna slightly clavate at apex, with 20–23 segments (21 in holotype); sub-basal flagellomeres about 1.8 and subapical flagellomeres 1.0–1.2× as long as broad. Mandible slender, with upper tooth distinctly longer than lower tooth. Malar space 0.7–0.8× as long as basal width of mandible. Clypeus 2.9× as broad as long, slightly convex or flat in lateral view, smooth, sparsely punctate in upper half. 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 punctures. Occipital carina complete.

Mesosoma with mesoscutum finely and densely punctate on granulate background. Notaulus with short wrinkle. Mesopleuron finely punctate, granulate peripherally and almost smooth centrally. Foveate groove in anterior half of mesopleuron, moderately deep, strongly oblique, with transverse wrinkles. Propodeal spiracle separated from pleural carina by 1.5–2.5 diameters of spiracle. Propodeum with basal keel 0.36× 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 weak, usually not reaching transverse carina anteriorly.

Fore wing length 3.55 mm. First abscissa of radius straight, longer than width of pterostigma. Metacarp almost reaching apex of fore wing. Second recurrent vein postfurcal. Intercubitus usually about as long as abscissa of cubitus between intercubitus and second recurrent vein. Hind wing with nervellus slightly reclivous, slanted at 10–15°.

Legs slender. Hind femur 4.45× as long as broad and 0.82× as long as tibia. Spurs of hind tibia almost straight. Tarsal claws not pectinate, strongly curved.

Tergite 1 of metasoma very slender, 4.4× as long as broad posteriorly, smooth, with small glymma and petiole round in cross-section. Second tergite 1.65× as long as broad anteriorly; thyridial depression distinct, 1.5–2.5× as long as broad. Ovipositor upcurved, with shallow dorsal subapical depression; sheath about 2.8× as long as hind tibia and 3.0× as long as first tergite.

Head, mesosoma and tergite 1 of metasoma black; pronotum anteriorly and upper part of mesopleuron sometimes reddish brown. Scape and pedicel of antenna, palpi, mandible (except for blackish teeth), lower half of clypeus and tegula brownish yellow. Flagellum brownish basally to fuscous apically, or more or less entirely black. Pterostigma brown. Legs yellow-brown to brown. Metasoma behind tergite 1 predominantly brown, ventrally yellowish; tergites 2+ with hind margin more or less yellowish.

Male. Similar to female but flagellum distinctly tapered towards apex, with 25–27 segments, malar space shorter, tergite 2 and thyridial depression longer.
