Female. Length. 10.5 mm, excluding ovipositor.
Colour. Head black, antennae dark-brown, mandibles orange-brown, apical tooth dark brown; lateral clypeus orange-brown; metasoma black dorsally, pronotum orange-brown, mesopleuron and metepimeron black, metapleuron black, except anterior lower third metepisternum orange; propodeum orange; legs generally dark brown; fore legs pale orange on apex of coxa, apex and base of trochanter, femur and tibia, dorsal surface of fore tibia pale orange; posterior surface of mid coxa orange-brown, basal third and dorsal surface mid tibia cream; inner basal surface hind coxa with orange spot, hind tibia cream basally inner surface, basal half basitarsus cream; wings hyaline; wing veins and pterostigma dark brown; ovipositor brown, sheaths dark brown, tip cream.
Head. Head elongate, 1.48 x longer than wide when viewed dorsally; face punctulate, pubescent; frons without frontal carina, punctate near antennal scrobes, with punctulate microsculpture, pubescence denser near scrobes; vertex with punctulate microsculpture; occipital carina narrow; gena with scattered punctures, punctulate microsculpture, and short pubescence; malar space 0.04 x height eye; clypeus 3.04 x as wide as high, margin sinuate, with scattered long setae; mandibles broad, with one large medial tooth; distance from lateral ocellus to eye margin 1.00 x distance between lateral ocelli; scape 2.00 x length pedicel; first flagellomere 0.49 x as long as scape, 0.57 x length second flagellomere.
Mesosoma. Propleuron 1.64 x length pronotum (Figs 10, 16); propleuron and pronotum with three distinct lobes, punctulate microsculpturing, and dense, short pubescence; mesoscutum (Figs 10–11) in lateral view rounded antero-dorsally, medial and lateral lobes with punctulate microsculpture, and very short setae; parapsidial lines distinct; notauli U-shaped, scrobiculate, indistinct (Fig. 11); mesoscutellum and axillae with punctulate microsculpture; mesopleuron and metapleuron areolate-rugose, except mesepimeron punctulate, dense, short pubescence; mesopleural groove broad, rugose (Fig. 10); propodeum areolate-rugose, flattened medial carina, posterior margin weakly scrobiculate medially; hind coxa punctate-rugulose; trochanter rugulose, groove present; hind femur imbricate with a few scattered punctures, pubescence short; prefemur small, about one-third length of trochanter; hind tibia imbricate with a few scattered punctures, pubescence short; hind femur 0.76 x length hind tibia; hind tibia without ventro-apical pecten of short robust spines; hind tarsomeres 1–5 with ventro-apical pecten of short robust spines, ts1, 3.46 x length ts2; ts2, 1.41 x length ts3; ts3, 1.70 x length ts4; ts4 0.48 x length ts5; hind tarsal claw 0.62 x length ts5; fore wing with first discal cell subtrapezoidal formed by veins 1-Rs+M, 1-Cu, 2-Cu and 1m-cu; fore wing vein 2-M tubular in basal third, not ending with small node, remaining two-thirds nebulous (Fig. 4); hind wing with only vein R+Rs, three equidistant hamuli.
Metasoma. 2.64 x length of mesosoma; T1 punctate-rugulose; T2 with imbricate microsculpture with a few small punctures dorso-posteriorally, remaining tergites with imbricate microsculpture, scattered punctures dorsally, pubescence short; subgenital sternite with Y-shaped notch; exserted part of ovipositor 1.57 mm.
Male. Unknown.
Etymology. This species is named after the type locality, Sarramea, Grand Terre, New Caledonia.
Comments. Gasteruption sarramea sp. nov. has a distinctive elongate head (Figs 10, 16–17), making it readily distinguishable from both G. l a c o u l ee sp. nov. (Figs 12–13) and G. maquis sp. nov. (Figs 14–15), both of which have a more-or-less quadrate head when viewed dorsally. Also, the propleuron of G. sarramea (Figs 10, 16) is much longer than the propleuron in either G. lacoulee (Figs 6, 12) or G. maquis.
