Description. Female. Body length about 1.8 mm. Body dark, with bright metallic luster in places ( Figs 8View FIGURE 8, 9AView FIGURE 9): face coppery ( Fig. 9B –DView FIGURE 9), propodeum and Gt1 bright metallic green ( Fig. 8DView FIGURE 8); antennal scape pale, rest of antenna dark, legs pale brown but with green metallic luster in reflected light, fore wing with weak dark cloud under stigmal vein, first three tarsomeres pale brown, terminal tarsomere much darker ( Fig. 8A –CView FIGURE 8).

Head about 1.3× as broad as mesosoma ( Fig. 9AView FIGURE 9), 3.4× as broad as long in dorsal view, totally smooth, only with scrobes traced as very shallow grooves, and covered by sparse very short setae. Occipital margin with a strong carina ( Fig. 9AView FIGURE 9). POL about 2.0× OOL. Head in frontal view ( Fig. 9B –DView FIGURE 9) about 1.4× broader than high. Eye nearly bare; its height 1.3× longer than malar space. Mouth opening slightly concealed under swollen lower face ( Figs 9C –DView FIGURE 9, 10A, DView FIGURE 10), its breadth about 0.5× malar space; mandible without cutting edge. Upper margins of antennal toruli situated just slightly above level of lower eye margins. Combined length of pedicel and flagellum slightly longer than maximum  head breadth (measured between outer eye margins). Scape 6.5–7.5× as long as broad, and about 0.7× as long as head height; pedicel nearly 2.0× as long as broad. Funicle with F1 about 3.5×, F2 and F3 about 3.0× as long as broad; clava about 3.5× as long as broad.

Mesosoma about 1.4× as long as broad ( Fig. 8DView FIGURE 8). Pronotum relatively narrow, its collar situated notably lower than level of convex mesoscutum, so it is hardly visible in dorsal view, bearing a weakly developed transverse carina and somewhat bulged lateral shoulders ( Fig. 8D, EView FIGURE 8). Mesoscutum notably convex in lateral view, with light reticulation, notaular depressions marked only anteriorly as light thin sutures, indistinct posteriorly ( Fig. 8DView FIGURE 8, 9AView FIGURE 9). Transscutal line nearly straight ( Fig. 8DView FIGURE 8). Mesoscutellum moderately convex, with light reticulation throughout. Axilla with lighter sculpture than mesoscutum and mesoscutellum, and with 1 short seta. Dorsellum short, subrectangular, with two shallow foveae anterolaterally. Propodeum smooth and shiny ( Fig. 8D, EView FIGURE 8), with weak anterior groove; submedian carinae subparallel or weakly diverging posteriorly and ending with a short flange (not a distinct nucha); propodeal callus bare. Submedian areas of propodeum 1.3× as broad (measured between lateral plicae) as long (measured from anterior margin of propodeum to its posterior margin). Fore wing 2.4× as long as broad ( Fig. 8B, CView FIGURE 8), with speculum open below (cubital fold with one short seta at underside of wing); subcosta of submarginal vein with two very short setae (as long as breadth of parastigma basally, hardly visible in dry specimens); admarginal setal line stretches along costal margin from stigmal vein nearly to submarginal break; marginal vein slightly longer than narrow costal cell, stigmal vein somewhat elongate, at least 2.0× longer than marginal vein in its broadest part, with uncus larger than stigma; postmarginal vein rather short, reduced in size. WIP with wide blue-green area apically and altering red and green bands behind it ( Fig. 8CView FIGURE 8). Metatibial spur as long as breadth of metatibia, about 0.6× as long as metabasitarsus. Metatibia about 1.4× as long as metatarsus, metabasitarsus as long as breadth of hind tibia. Metasoma slightly longer than head plus mesosoma in dorsal view ( Fig. 8AView FIGURE 8). Metasomal petiole about 0.4× as long as propodeum, robust, somewhat convex, its upper side coriaceous rugose, but underside reticulated. Gaster elongate ovate, about 2.0–2.5× as long as broad; Gt1 smooth, polished, occupying approximately 1/3 length of gaster, Gt7 elongate, slightly more than 2.0× longer than wide ( Figs 8A –CView FIGURE 8, 9EView FIGURE 9, 10BView FIGURE 10).

Male ( Fig. 9FView FIGURE 9, 10D, EView FIGURE 10). Very similar to female except for: antennal scape about 5.0× as long as broad; pedicel about 1.6–1.7× as long as broad, F1 about 3.2–3.3×, F2 1.7–1.8×, F3 about 1.5× as long as broad; clava about 3.0× as long as broad. Metasoma about 0.8× as long as head plus mesosoma. Metasomal petiole slightly longer than propodeum. Gaster subpentagonal, about 1.3× as long as broad.

Etymology. The specific epithet consists of afro – (reflecting distribution of the species in Africa) and – teres (Latin for “smooth, polished”) reflecting the unusual face of the species with neither frontal sutures, no sculpture.

Distribution. South Africa, Zimbabwe, Malawi, Kenya, Uganda, DRC, Cameroon.

Host. Unknown. Some considerations on possible hosts of this species are mentioned below in Discussion.

Comparative notes. The species is very recognizable as a representative of its species group in having the convex polished head and light dorsal sculpture. It could be confused with P. kafroteres  ( Fig. 11View FIGURE 11), from which it differs by the shorter metasomal petiole and less convex mesoscutellum.
