Diagnosis
Both sexes
Gena not hollowed at mouth corner (Fig. 3C). Clypeus striate, not well delimited. Clypeal margin with two large lobes separated by deep incision (Fig. 3C). Mandibles not unusually large (Fig. 3C). Pronotal collar with anterior margin rounded, not carinate (Fig. 3A–B). Scutellum longer than mesoscutum. Toruli much higher than centre of face (Fig. 3C). Fore wing (Fig. 3F) sparsely setose, speculum large, reaching stigmal vein thus making admarginal setae on ventral side of wing easily visible. Stigma very large, its height about equal to minimum distance from stigma to PMV. All coxae metallic (Fig. 3A). Hind femur yellowish-brown, without metallic reflections (Fig. 3A–B).
Female
Claval apex without spicula (Fig. 3G). Metasoma (Fig. 3E) with gt1 and gt3 with posterior margin emarginate or incised, respectively; gt4 distinctly enlarged, much larger than gt3. Head in frontal view without contrasting colours, gradually becoming darker above toruli (Fig. 3C). Metasoma mostly blue (Fig. 3E). Body setation white, conspicuous (Fig. 3A, C).
Male
Flagellar setae depressed. Clava with short spike-like terminal process (Fig. 3H). Metasoma dark, without a dorsal pale spot.
Etymology
This species is named after the outstanding chalcidologist John Noyes, the collector of the type specimens.

Description
Female holotype
BODY LENGTH. 2.1 mm.
COLOUR. Head (Fig. 3C) green becoming dark bluish above toruli, including vertex and occiput. Eyes dark brown, ocelli brown. Scape, pedicel and anelli reddish-brown, funicle and clava brown (Fig. 3G). Mandibles reddish-brown, teeth darker. Mesosoma bluish-green (Fig. 3A, D). Coxae as mesosoma. Trochanters, tibiae and tarsi except distal segment reddish-brown. Femora and distal tarsal segment darker (Fig. 3A). Wings hyaline (Fig. 3F). Tegulae and venation reddish-brown. Metasoma steel blue (Fig. 3E). Body setation white, conspicuous (Fig. 3A, C).
HEAD. Reticulate except clypeal region. Gena not hollowed at mouth corner (Fig. 3C). Clypeus not well delimited, striate. Clypeal margin with two large lobes separated by deep incision (Fig. 3C). Mandibles not unusually large (Fig. 3C). Toruli much higher than centre of face. Scrobes fairly deep. Scape reaching above level of vertex (Fig. 3C). Anelli transverse, all five funicular segments longer than wide, with moderately long setae. Claval apex without spicula (Fig. 3G). Relative measurements: head L: 35, W: 68, H: 50; eye H: 32, L: 25; POL: 15; OOL: 11; malar space: 15; scape L: 23, W: 5; pedicel L: 6, W: 4.5; pedicel plus flagellum L: 70; fu1 L: 10, W: 5; fu5 L: 8, W: 5; clava L: 17, W: 7.
MESOSOMA. Pronotal collar uniformly reticulate, anterior margin rounded off into vertical neck (Fig. 3A). Mesoscutum reticulate. Notauli barely visible among reticulation, occupying about half the length of mesoscutum. Scutellum as coarsely reticulate as mesoscutum, frenal area not delimited (Fig. 3D). Dorsellum very short, groove-like (Fig. 3D). Propodeal median area more superficially reticulate than scutellum, laterally delimited by sinuate plicae reaching nucha. Posterior part of nucha finely striate (Fig. 3D). Central part of prepectus finely reticulate. Mesopleuron with two reticulate areas: a large elongate one in anterior part, and an oval, much smaller one, in posterior part; adjacent areas smooth (Fig. 3A). Metapleuron finely reticulate, separated from propodeal callus by deep groove. Fore wing (Fig. 3F) with basal cell, including basal vein, bare except one or two scattered setae. Costal cell with an irregular line of setae in distal half. Disc sparsely setose. Speculum large, gradually narrowing and reaching stigmal vein. Admarginal setae on ventral side of wing in one irregular row. Stigmal height as long as distance from stigma to PMV (Fig. 3F). Relative measurements: mesosoma L: 70, W: 55, H: 47; mesoscutum L: 26, W: 55; scutellum L: 30, W: 30; propodeum L: 16; fore wing L: 130, W: 65; MV: 27; SV: 15; PMV: 20; stigma H: 7; distance from stigma to PMV: 7.
METASOMA (Fig. 3E). Acute at both ends, slightly collapsing dorsally. Gt1 greatly produced posteriorly, its hind margin medially emarginate. Gt3 with posterior margin medially incised. Gt4 not unusually enlarged, not larger than gt3. Relative measurements: metasoma L: 110, W: 39; gt1 L: 22, W: 25; gt2 L: 9, W: 31; gt3 L: 15, W: 39; gt4 L: 15, W: 37; gt5 L: 12, W: 31; gt6 L: 15, W: 21; syntergum L: 14, W: 5.
Male allotype
Differs from the female holotype mainly in the following. Body length: 1.5 mm. Metasoma uniformly dark brown, with some blue-green metallic reflections mainly on gt1. Body setation mostly darker, less conspicuous. Antenna 11263. Flagellar setae slightly denser, but not more erect than those of the female (Fig. 3H). Clava with short spike-like terminal process (Fig. 3H). MV 1.6 × SV. Metasoma much narrower anteriorly than posteriorly, distinctly shorter than head plus mesosoma, distal tergites partly retracted. Posterior margins of all tergites virtually straight. Metasoma L: 73, W: 22.
