(Figs 234, 235, 730, 961)
Diagnosis (female). Antennal clava with distinct constriction between C1 and C2, C2 and C3 yellowish-brown (Fig. 730); lower frons yellowish-brown to pale brown, non-metallic; frons with transverse carinae; with a short genal carina; midlobe of mesoscutum (Fig. 234) with strong longitudinal carinae; mesoscutellum (Fig. 234) with very weak reticulation, meshes elongate, submedian grooves distinct, slightly curved and diverging towards posterior part; dorsellum with a weak median carina; fore wing with a large fuscuous spot medially (Fig. 235); propodeum (Fig. 234) with a very strong but narrow median carina, and with strong reticulation, callus with two setae; petiole transverse with longitudinal carinae; gaster (Fig. 234) elongate; Gt 1 smooth and shiny, remaining tergites with weak reticulation. Similar to G. admirabilis, differs in having antennal flagellum shorter, head not so long (frontal view), and in having frenal groove on mesoscutellum narrower. Male flagellum with dorso-basal whorls of long setae present on F1–F4 and with ventro-basal whorls of long setae on C1–C2 (Fig. 961). Female holotype: length of body 2.4mm (paratypes 2.1–2.2mm).
Scape yellowish-white with dorsal edge dark brown, pedicel, funiculars and C1 dark brown, C2–3 yellowish-brown. Face below level of toruli yellowish-brown to pale brown, above level metallic bluish-green, antennal scrobes yellowish-brown; vertex metallic purple. Mesoscutum with sidelobes black with metallic tinges, midlobe metallic bluish-green; mesoscutellum metallic bluish-green with anterior two-thirds of median part golden-purple; propodeum dark brown. Legs with fore and hind coxae white (fore coxa predominantly dark brown in one paratype), mid coxa dark brown; trochanters, femora and tibiae dark brown with apex of tibiae yellowish-brown; T1–3 yellowish-brown, T4 dark yellowish-brown. Fore wing with a large fuscous spot medially, wings otherwise hyaline. Petiole yellowish-brown. Gastral tergites metallic purple; gonoplac black.
Antenna with distinct constriction between C1 and C2. Face below level of toruli with weak reticulation and shiny, clypeus smooth, frons with transverse carinae, antennal scrobes with weak reticulation; with a short genal carina close to mouth opening. Vertex with very weak reticulation. Occipital margin carinate.
Pronotum very large with sides parallel, with strong reticulation, meshes isodiametric, with posterior margin smooth. Mesoscutum with strong reticulation on sidelobes, meshes isodiametric, midlobe with elongate carinae, with four adnotaular setae in a single row. Mesoscutellum with very weak reticulation, meshes elongate; submedian grooves distinct, slightly curved and diverging towards posterior part; with two pairs of setae on lateral parts, one pair close to posterior margin of mesoscutellum and one pair placed medially; frenal groove narrow and subdivided by longitudinal carinae. Dorsellum with weak reticulation and shiny, with a weak median carina. Propodeum with a narrow strong median carina; with strong reticulation; callus with two setae. Coxae with weak reticulation and shiny. Fore wing with 3&5 setae on dorsal surface of submarginal vein; speculum closed; costal setal row unbroken.
Petiole transverse with strong longitudinal carinae, otherwise smooth. Gaster elongate; Gt
1 smooth and shiny, remaining tergites with weak reticulation.

Hosts. Reared from galls induced by Zalepidota (Diptera: Cecidomyiidae) on Piper crassinervium (Piperaceae). The galls consist of swellings of the leaf veins, petioles and stems.
Distribution. Costa Rica.
