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 View FIGURES 6 – 11 , 16 View FIGURES 12 – 17 ); propleuron and pronotum with three distinct lobes, punctulate microsculpturing, and dense, short pubescence; mesoscutum ( Figs 10–11 View FIGURES 6 – 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 View FIGURES 6 – 11 ); mesoscutellum and axillae with punctulate microsculpture; mesopleuron and metapleuron areolate-rugose, except mesepimeron punctulate, dense, short pubescence; mesopleural groove broad, rugose ( Fig. 10 View FIGURES 6 – 11 ); 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 View FIGURES 2 – 5 ); 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 View FIGURES 6 – 11 , 16–17 View FIGURES 12 – 17 ), making it readily distinguishable from both G. l a c o u l ee sp. nov. ( Figs 12–13 View FIGURES 12 – 17 ) and G. maquis sp. nov. ( Figs 14–15 View FIGURES 12 – 17 ), both of which have a more-or-less quadrate head when viewed dorsally. Also, the propleuron of G. sarramea ( Figs 10 View FIGURES 6 – 11 , 16 View FIGURES 12 – 17 ) is much longer than the propleuron in either G. lacoulee ( Figs 6 View FIGURES 6 – 11 , 12 View FIGURES 12 – 17 ) or G. maquis .
