( Figs 5 View Figs , 582, 583 View Figs 580–583 , 919 View Figs 915–923 , 1095)

Diagnosis (female). Antennal flagellum short and clavate (Fig. 1095); genal carina present; mesoscutellum ( Fig. 582 View Figs 580–583 ) completely flat, in same plane as dorsellum and propodeum, with very weak reticulation on median part, lateral parts with slightly stronger reticulation, meshes elongate, submedian grooves distinct, straight and diverging towards posterior part; dorsellum with weak median carina; propodeum ( Fig. 582 View Figs 580–583 ) with strong reticulation, callus with 3–4 setae; gaster ( Fig. 582 View Figs 580–583 ) dorsally flattened, medio-basal Gt1 with a blunt edge shaped like an inverted U (as in Fig. 24 View Figs 23–28 ), tergites with engraved and strong reticulation.

Female holotype: length of body 2.3mm (paratypes 1.8–2.6mm).

Scape yellowish-brown with apico-dorsal part pale brown, pedicel brown, flagellum dark brown. Head with frons and vertex golden-green, clypeus dark brown. Thoracic dorsum golden-green. Legs with coxae golden-green; trochanters yellowish-brown; fore and mid femora yellowish-brown, hind femur with basal half dark brown and apical half yellowish-brown; tibiae yellowish-brown; T1–3 yellowish-brown, T4 infuscate. Petiole black. Gaster with Gt1 metallic bluish-green in anterior two-thirds and metallic purple in posterior one-third, remaining tergites metallic purple; gonoplac black.

Antenna with constriction between C1 and C2. Frons with strong reticulation, antennal scrobes with weak reticulation and clypeus smooth; with genal carina. Vertex with strong reticulation outside ocellar triangle, with wrinkled sculpture inside ocellar triangle. Occipital margin with an edge behind ocellar triangle.

Mesoscutum slightly flattened, with strong reticulation, meshes isodiametric on sidelobes, slightly elongate on midlobe; midlobe with a complete median groove, with eight scattered adnotaular setae. Mesoscutellum flat, with very weak reticulation on median part, lateral parts with slightly stronger reticulation, meshes elongate; submedian grooves distinct, straight and diverging towards posterior part; with six setae scattered over lateral parts. Dorsellum flat and in same plane as mesoscutellum, with weak sculpture, median carina weak. Propodeum with a strong median carina that expands both anteriorly and posteriorly; with strong reticulation; callus with 3–4 setae. Fore and mid coxae with weak reticulation, hind coxa with strong reticulation. Fore wing with four setae on dorsal surface of submarginal vein; speculum closed; costal setal row broken.

Petiole very short, just a narrow band. Gaster elongate; medio-basal Gt 1 with a blunt edge shaped like an inverted U; tergites with engraved and strong reticulation.

Male. Unknown.

Hosts. Reared from leaf galls induced by Monitoriella elongata Hedqvist ( Hymenoptera : Braconidae ) on Philodendron radiatum ( Araceae ). ( Fig. 5 View Figs ). Evidence from gall dissections suggests that the larva of G. philodendrae feeds on the braconid gall-inducer, as opposed to one of the other hymenopterans ( Eurytomidae Pirenidae , Pteromalidae ) present in these galls ( Infante et al. 1995).

Distribution. Costa Rica.

Material examined.

Holotype ♀ COSTA RICA, Limón, 4km NE Bataam , x-xi.1999, P. Hanson ( NHMUK) . Paratypes (15♀, CNC, MZLU, MZUCR, NHMUK): 11♀ COSTA RICA, Heredia, OTS La Selva, iii-iv.2002, from leaf gall Philodendron radiatum, P. Hanson ; following from same locality and host as previous but collected 5.iii.1994 (1♀), i.1998 (1♀, this also with information on gallmaker, Monitoriella sp. ) ; 1♀ COSTA RICA, Limón, 13km W, 3km N Guápiles, 9.xii.1990, from Philodendron radiatum leaf gall, Paul Hanson ; 1♀ from same locality as previous but collected 20.xi.1991 .

Etymology. Named after host plant of the gall-inducer from which this species was reared.
