(Fig. 7)
Diagnosis. Head in dorsal view (Fig. 7D) about 2.5× as broad as long, completely smooth, medially convex, with distinct frontal and scrobal sutures (Fig. 7F), lower face slightly narrowed: malar space about 0.5× as long as eye height, mouth opening about 0.7× as long as malar space; upper margins of antennal toruli situated slightly above level of lower eye margins (Fig. 7F); mandible with two teeth; occipital margin sharp and distinctly curved (Fig. 7D); antennal scape pale yellow; mesoscutum and mesoscutellum mostly with light sculpture and smooth median strip on mesoscutellum, notauli marked anteriorly by fine sutures and inconspicuous posteriorly (Fig. 7C, D); entire dorsum with setae, which longer than flagellar setae (this may be correlated with smaller body size); mesoscutellum with one pair of setae; propodeum with indistinct nucha bearing inconspicuous foveae, submedian areas of propodeum about 1.4× as broad as long, submedian carinae diverging posteriorly, with short median carina between them (Fig. 7D); propodeal callus with 3 setae; metatibial spur 0.8× as long as metabasitarsus, slightly less than 2.0× as long as breadth of metatibia; subcosta of submarginal vein with two setae (of same length as the setae of dorsum); forewing speculum open, but with cubital setal line consisting of 5 setae at underside of wing; fore wing transparent; WIP with wide violet field apically (Fig. 7E); metasomal petiole very slightly shorter than propodeum; gaster elongate ovate, about 2.7× as long as broad; Gt7 elongate, about 3.0× as long as broad basally (Fig. 7C).
Type material. Holotype ♀, Gabon, Ogoove-Maritime, Reserve de la Moukalaba-Dougoua, 12.2 km 305° NW Doussala; 02°17'00"S, 10°29'83" E, 110 m, 2. III. 2000, sweep, Coastal Lowland Rainforest, elephant path (S. van Noort) GA00-S41, SAM-HYM-P00 23554 (Fig. 7, deposited in: SAMC).
Description. Female. Body length about 1.7 mm. Body dark with bluish tint on smooth dorsal areas and with bright green metallic luster in face and mesosterna; mandible with two small teeth; antennal scape pale yellow, pedicel dark dorsally, but pale ventrally, rest of antenna dark brown, legs pale, wings transparent, first three tarsomeres pale, terminal tarsomere dark (Fig. 7A–D).Head smooth throughout (Fig. 7D, F), about 1.3× as broad as mesosoma, 2.5× as broad as long in dorsal view, with sparse bristles on vertex. Occipital margin with sharp carina (Fig. 7D). POL about 1.7× OOL. Head in frontal view about slightly broader than high (Fig. 7F). Eye almost bare; its height about 2.0× longer than long malar space. Mouth opening about 0.75× as long as malar space; mandible with two teeth. Upper margins of antennal toruli situated slightly above level of lower eye margins. Combined length of pedicel and flagellum 0.8–0.9× maximum head breadth. Scape nearly 4.0× as long as broad, and about 0.4× as long as head height; pedicel nearly 1.3× as long as broad. Funicle with F1–F3 slightly longer than broad; clava about 2.5–2.7× as long as broad.
Mesosoma about 1.5× as long as broad (Fig. 7D). Pronotum narrow, its collar situated slightly lower than level of convex mesoscutum, visible as a narrow strip in dorsal view, bearing rather weak transverse carina and small lateral shoulders. Mesoscutum weakly convex in lateral view, lightly reticulated with wide meshes, notaular depressions marked anteriorly as fine sutures, indistinct posteriorly. Anterior margin of mesoscutellum slightly advanced medially. Mesoscutellum nearly flat, lightly reticulated laterally, but smooth medially. Axilla with notably lighter sculpture than mesoscutum and mesoscutellum, and with 1 short seta. Dorsellum very narrow, nearly reduced. Propodeum smooth and shiny, with anterior groove, its submedian areas 1.4× as broad as long; submedian carinae straight, diverging posteriorly with a straight short median carina between them. Posterior part of propodeum with somewhat elongate, but not margined nucha; propodeal callus with three setae.
Fore wing 2.3× as long as broad, with speculum partially closed below (with long basal but short cubital setal line of 5 setae at underside of wing); marginal vein nearly 6.0× longer than narrow costal cell; subcosta of submarginal vein with two setae, which of same length as the setae of dorsum; stigmal vein knob-like, slightly shorter than postmarginal vein, 2.0× longer than marginal vein in its broadest part, with moderate-sized stigma and short uncus. WIP with wide violet area apically, followed by narrow blue and red curved stripes, and a subtriangular green area under marginal vein (Fig. 7E).
Metatibial spur 1.3× as long as breadth of metatibia, about 0.8× as long as metabasitarsus. Metatibia about 1.2× as long as its tarsus, which slightly less than 2.0× as long as breadth of its tibia.
Metasoma about 1.25× longer than head plus mesosoma (Fig. 7A, C). Metasomal petiole very short and robust, coriaceous, distinctly shorter than propodeum. Gaster elongate ovate, about 2.7× as long as broad; Gt1 smooth, polished, but laterally with short patch of reticulation bearing short setae, occupying about 1/4 of length of gaster, Gt7 elongate, about 3.0× as long as broad basally.
Male. Unknown.
Etymology. The specific epithet is the name of kingdom which preceded what is Gabon now.
Distribution. Gabon.
Host. Unknown.
Comparative notes. The holotype habitually looks like a small specimen of P. rohombaya, but differs from this species as discussed above.
