Fig. 4
Diagnosis
Both sexes
Gena not hollowed at mouth corner (Fig. 4C). Clypeus striate, not well delimited. Clypeal margin with small lobes separated by shallow emargination (Fig. 4C). Mandibles not unusually large (Fig. 4C). Pronotal collar with anterior margin slightly raised but not carinate. Scutellum shorter than mesoscutum. Toruli above centre of face, although not very high (Fig. 4C). Fore wing (Fig. 4F) densely setose, speculum smaller, not reaching stigmal vein thus admarginal setae on ventral side of wing not easily visible. Stigma very large, its height at least equal to minimum distance from stigma to PMV. Fore and mid coxae not metallic (Fig. 4A–B). Hind femur yellowish-brown.
Female Claval apex without spicula (Fig. 4G). Metasoma with all gastral tergites normally developed, each with its posterior margin entire (Fig. 4E). Head in frontal view with contrasting colours, bright green below toruli and blackish above (Fig. 4C). Metasoma mainly brown (Fig. 4E). Body setation light brown to whitish, not conspicuous except on the head (Fig. 4C).
Male
Flagellar setae erect. Clava without spike-like terminal process (Fig. 4H). Metasoma brown, with a dorsal pale spot.

Etymology

Description
Female holotype
BODY LENGTH. 2.1 mm.
COLOUR. Head (Fig. 4C) bright green except bluish-black genae, scrobes, vertex and occiput. Eyes dark brown, ocelli reddish-brown. Scape and pedicel reddish-yellow, flagellum reddish-brown (Fig. 4G). Mandibles reddish-yellow, teeth reddish-brown. Mesosoma dark blue except blue green lateral corners of mesoscutum, axillae, lateral sides of scutellum, and anterior margin of mesopleuron (Fig. 4A, D). Fore and mid coxae reddish-yellow, hind coxa dorsally brown, with weak metallic reflections. Trochanters, tibiae and tarsi except distal segment reddish-yellow. Femora and last tarsal segment yellowish-brown (Fig. 4A). Wings hyaline (Fig. 4F). Tegula reddish-yellow, venation yellowish-brown. Metasoma brown, with some weak bluish reflections (Fig. 4E). Body setation light brown to whitish, not conspicuous except on lower face (Fig. 4C).
HEAD. Reticulate except clypeal region. Gena not hollowed at mouth corner (Fig. 4C). Clypeus not well delimited, striate. Clypeal margin with short lobes separated by broad emargination (Fig. 4C). Mandibles not unusually large (Fig. 4C). Toruli higher than centre of face (Fig. 4C). Scrobes shallow. Scape reaching above level of vertex (Fig. 4C). Anelli transverse, all five funicular segments longer than wide, with moderately long setae. Claval apex without spicula (Fig. 4G). Relative measurements: head L: 25, W: 62, H: 47; eye H: 25, L: 20; POL: 13; OOL: 10; malar space: 16; scape L: 26, W: 4.5; pedicel L: 7.5, W: 3.5; pedicel plus flagellum L: 61; fu1 L: 7, W: 4.5; fu5 L: 7, W: 4.5; clava L: 16, W: 5.
MESOSOMA. Pronotal collar with reticulation becoming shallower posteriorly, anterior margin slightly raised but not carinate. Mesoscutum reticulate. Notauli barely visible among reticulation, occupying almost half the length of mesoscutum. Scutellum as coarsely reticulate as mesoscutum, frenal area not delimited (Fig. 4D). Dorsellum very short, as a smooth band (Fig. 4D). Propodeal median area more coarsely reticulate than scutellum, laterally delimited by sinuate plicae reaching nucha. Posterior part of nucha striate reticulate (Fig. 4D). Central part of prepectus finely reticulate. Mesopleuron reticulate except for smooth triangular area under hind wing base (Fig. 4A). Mesepisternum with small depression before mid coxa. Metapleuron finely reticulate, with small depression in lower part, separated from propodeal callus by deep groove. Fore wing (Fig. 4F) with basal cell bare, basal vein with a few setae. Costal cell with two irregular lines of setae in distal half. Disc densely setose. Speculum moderate, reaching to proximal end of marginal vein. Admarginal setae on ventral side of wing in two irregular rows under marginal vein. Stigmal height slightly longer than distance from stigma to PMV (Fig. 4F). Relative measurements: mesosoma L: 66, W: 51, H: 49; mesoscutum L: 28, W: 51; scutellum L: 25, W: 29; propodeum L: 12; fore wing L: 145, W: 64; MV: 33; SV: 17; PMV: 25; stigma H: 8; distance from stigma to PMV: 7.
METASOMA (Fig. 4E). With sides almost parallel for about 3/4 of its length, strongly collapsing dorsally. Gt1 slightly produced posteriorly, none of the other gastral tergites enlarged or medially incised. Relative measurements: metasoma L: 133, W: 32; gt1 L: 23, W: 24; gt2 L: 3, W: 25; gt3 L: 20, W: 28; gt4 L: 20, W: 32; gt5 L: 20, W: 32; gt6 L: 20, W: 30; syntergum L: 12, W: 18.
Male allotype
Differs from the female holotype mainly in the following. Body length: 1.9 mm. Metasoma with pale spot in basal half.Antenna 11263. Flagellar setae as in female, i.e., erect, but somewhat denser (Fig. 4H). Petiole more visible. Metasoma about equal to head plus mesosoma, posterior end more blunt, distal tergites partly retracted. Metasoma L: 95, W: 38.
Variation
Females
Body length: 2.00–2.25. mm. Greenish areas of mesosoma more or less extended. Stigmal height from equal to slightly longer than maximum distance between stigma and PMV. POL 1.3–1.5 × OOL. MV 1.8–2.0 × SV. Metasoma length 4.0–4.2 × width.
Males
Body length: 1.5–2.0 mm. Greenish areas of mesosoma more or less extended. Shape and size of metasoma whitish spot variable. Shape and length of metasoma variable according to degree of collapsation of gastral tergites.
Distribution
D.R. Congo.
Hosts
