(Figs 602, 603, 868, 994)
Diagnosis (female). Antenna with distinct constriction between C1 and C2 (Fig. 868); genal carina present; mesoscutellum (Fig. 602) with median part with very weak reticulation, lateral parts rugose, outer margin of submedian grooves absent; dorsellum with median carina; propodeum (Fig. 602) with strong reticulation, propodeal callus with three setae; petiole transverse with some longitudinal carinae; gaster (Fig. 602) 2.5× as long as wide, relatively narrow, 0.82× as wide as width of mesoscutum, medio-basal Gt 1 with a carina shaped like an inverted U (as in Fig. 26), tergites with very strong large-meshed reticulation and with dorsal part ±flattened.
Female holotype: length of body 2.1mm (paratypes 2.2–2.6mm).
Scape dark yellowish-brown with dorsal edge brown, pedicel and flagellum dark brown. Head with frons, including scrobes, and vertex metallic bluish-green, clypeus dark brown. Mesoscutum and mesoscutellum golden-green, propodeum black with golden-green tinges. Legs with fore and hind coxae golden-green, mid coxa dark brown; trochanters, femora and tibiae yellowish-brown; T1–3 yellowish-brown, T4 dark brown. Petiole black. Gaster black with golden-green tinges; gonoplac black.
Antenna with a strong constriction between C1 and C2. Frons with strong reticulation, clypeus smooth, antennal scrobes with weak reticulation; with genal carina. Vertex with strong reticulation outside ocellar triangle, with wrinkled sculpture inside ocellar triangle; with a carina between posterior ocelli in posterior part.
Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe, midlobe rugose close to notauli; with a weak but complete median groove; with 11 scattered setae on rugose parts. Mesoscutellum with median part with very weak reticulation, lateral parts rugose; outer margin of submedian grooves absent; lateral parts with 14 scattered setae. Dorsellum with weak sculpture and shiny, with median carina. Propodeum with a strong median carina that expands posteriorly; with strong reticulation; callus with three setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with five setae on dorsal surface of submarginal vein; speculum closed; costal setal row unbroken.
Petiole transverse with some longitudinal carinae, otherwise smooth and shiny. Gaster elongate; medio-basal Gt 1 with a carina shaped like an inverted U; tergites with very strong reticulation with large meshes and dorsal surface ±flattened.

Hosts. Reared from a leaf gall induced by an unidentified Cecidomyiidae on Schefflera rodriguesiana (Araliaceae). The gall is spherical, up to 10 mm in diameter, detachable and usually found on the underside of the leaf.
Distribution. Costa Rica.
Material examined.
Holotype ♀ COSTA RICA, Heredia, 6km ENE Vara Blanca, 10°11’N, 84°07’W, 2000m, 10.iii.2002, INBio, OET, ALAS (NHMUK). Paratypes (4♀ 2♂, MZLU, NHMUK): COSTA RICA, Cartago, Rio Macho, v.1998, Schefflera rodrigueziana spherical leaf gall.
Etymology. Named after the host plant of the gall from which this species was reared.
Remarks. The female paratypes are bleached by light.
