Description. Female. Body length about 2.2–2.4 mm. Body dark, with bright metallic luster in following areas: face golden green ( Figs 12C View Figure , 17A View Figure ), propodeum, lateral and ventral mesosoma, coxae and Gt1 dark blue ( Fig. 12A, D, E View Figure ); entire antenna and legs dark, fore wing with broad dark spot medially, first two tarsomeres pale brown, third one darker and terminal tarsomere much darker ( Fig. 12A View Figure ).

Head about 1.3× as broad as mesosoma ( Figs 12A, D View Figure , 17E View Figure ), 3.0× as broad as long in dorsal view, lightly reticulated throughout ( Figs 12C View Figure , 17A View Figure ), apart from lower face; with sparse bristles on vertex and along eye orbits. Border between upper and lower face marked by weak elevation, but without ridge or carina ( Fig. 13F View Figure ). Occipital margin deeply concave and marked by sharp carina ( Fig. 12F View Figure ). POL about 1.4× OOL. Head in frontal view about 1.4× as broad as high. Eye bare; its height 1.2× as long as malar space. Breadth of mouth opening about 0.6× malar space (malar space about 1.7× mouth opening), anterior margin of clypeus slightly produced; mandible wide, rounded, with two teeth ( Fig. 13D View Figure ). Upper margins of antennal toruli situated below level of lower eye margins at a distance equal to major diameter of torulus ( Figs 12C View Figure , 13A, C View Figure ). Combined length of pedicel and flagellum slightly longer than maximum  head breadth (measured between outer eye margins). Scape 6.7–6.8× as long as broad, and about 0.5× as long as head height; pedicel nearly 2.3× as long as broad. Funicle with F1 about 6.0×, F2 3.8×, F3 about 3.0× as long as broad; clava about 2.5× as long as broad.

Mesosoma ( Figs 12D, E View Figure , 13A, B View Figure ) about 1.4–1.5× as long as broad. Pronotum narrow, its collar situated somewhat lower than level of moderately convex mesoscutum, visible in dorsal view as a narrow strip, bearing sharp transverse carina and small lateral shoulders ( Figs 12D View Figure , 13B, F View Figure ). Mesoscutum convex anteriorly, relatively flat posteriorly, as well as mesoscutellum, finely reticuled; notauli marked as fine sutures anteriorly, and as very shallow depressions posteriorly ( Figs 12D View Figure , 13B View Figure ). Transscutal line straight ( Fig. 12D View Figure ). Axilla lightly but distinctly reticulated, with 1 short seta ( Fig. 13B View Figure ). Scutellum nearly flat, reticulated with wide elongate meshes in 2/3 and rounded meshes in about posterior 1/3 ( Fig. 13B View Figure ). Dorsellum narrow ( Fig. 13E View Figure ), subrectangular, without outlined foveae but with distinct lateral margins (this condition may be resultant from fused foveae). Propodeum ( Fig. 18A View Figure ) nearly smooth, but coriaceous along supracoxal flange, with short anterior groove under dorsellum and small pits on sides of anterior grooves; median coriaceous strip delimited by submedian carinae notably diverging posteriorly and ending up with distinct coriaceous nucha bearing two large indistinctly margined pits; propodeal callus with 3 setae.

Fore wing 2.6× as long as broad, with speculum partly closed below, with basal setal line present as two short setae and cubital setal line of 6 setae at underside of wing; subcosta of submarginal vein with two strong bristles, parastigma with one bristle; marginal vein 1.4× longer than relatively narrow costal cell, stigmal vein short, 1.5× as long as width of marginal vein in its broadest part, with rounded stigma and short uncus; postmarginal vein slightly longer than stigmal vein. WIP with altering narrow bands of violet (apical), blue, green, violet, and fuzzy greenviolet (near the dark cloud, Fig. 12B View Figure ). Metatibial spur slightly more than 2.0× as long as breadth of metatibia, 0.5× as long as metabasitarsus. Metatibia about 0.9× as long as metatarsus, metabasitarsus about 3.5× as long as breadth of metatibia.

Metasoma about 1.4× as long as combined length of head plus mesosoma in dorsal view ( Fig. 12A, B View Figure ). Metasomal petiole short, robust, rugose, with sharply margined collar; about 1.6× as long as propodeum. Gaster long ovate, about 2.6× as long as broad ( Fig. 12A View Figure ); Gt1 smooth dorsally, light alutaceous laterally, occupying slightly more than 1/3 length of gaster, Gt7 elongate, about 2.0× as long as its basal width.

Male. Unknown.

Etymology. The specific epithet means “soldier” in Swahili, a lingua franca in East Africa, and refers to the helmet-like head of this species.

Distribution. South Africa, Zimbabwe, Kenya, Tanzania, DRC, Ivory Coast.

Host. Unknown. Collected in very diverse biotopes in across Africa.

Comparative remarks. The species is easily distinguishable from all other representatives of Pediobius  by the remarkable habitus with the helmet-like, convex, coarsely sculptured head and darkened medially fore wings ( Figs 12 View Figure , 13 View Figure ). The only species it may be confused with is P. maleficus  , from which it differs as described below.
