Male. Length. 25.7 mm.
Colour. Head, mesosoma and metasoma black; lateral clypeus and mouthparts orange-brown, mandibles slightly darker; fringe of golden brown hairs on margin of clypeus; mesopleural groove brown; fore leg orangebrown; mid leg dark brown, except apical half of femur, tibia and basal half of basitarsus orange-brown; hind leg dark brown, slightly lighter near join of femur and tibia, apical half of basitarsus and remainder of tarsus cream; wings hyaline, with veins and pterostigma dark brown.
Head. More or less quadrate in dorsal view, 0.90 x longer than wide when viewed dorsally; face punctulate, pubescent laterally (Fig. 15); frons with frontal carina, punctulate; vertex punctulate, with short setae; gena punctulate, pubescent; malar space 0.14 x height eye; clypeus 3.22 x as wide as high, margin slightly concave,; mandibles broad, with one large medial tooth; distance from lateral ocellus to eye margin 0.73 x distance between lateral ocelli; scape 1.60 x length pedicel; first flagellomere 1.97 x as long as scape, 0.77 x length second flagellomere.
Mesosoma. Propleuron 0.80 x length pronotum, punctulate, pubescence long at base and near apex; pronotum rugose ventrally, punctulate dorsally, divided by scrobiculate groove; mesoscutum (Figs 8–9) in lateral view rounded antero-dorsally, medial and lateral lobes punctulate, with short setae, divided by crenulated U-shaped groove (Fig. 9); parapsidial lines distinct; notauli indistinct, percurrent; mesoscutellum and axillae punctulate; mesopleuron and metapleuron punctulate-strigate, coarser in meso- and metepisterna; mesopleural groove broad (Fig 8), smooth, weakly strigate dorsally grading to punctulate-rugose antero-ventrally; propodeum areolaterugose, posterior margin weakly scrobiculate; hind coxa imbricate, dorsally finely strigate; hind trochanter imbricate, groove present; femur imbricate, pubescence short; prefemur small, about half length of hind trochanter; hind tibia imbricate, pubescence short, dense; hind femur 0.61 x length hind tibia; hind tarsomeres 1-5 with ventroapical pecten of short robust spines, ts1, 3.34 x length ts2; ts2, 1.37 x length ts3; ts3, 1.90 x length ts4; ts4, 0.47 x length ts5; hind tarsal claw 1.45 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, tubular portion ending with small node, remaining two-thirds nebulous (Fig. 3); hind wing, vein M+Cu mostly nebulous, with short apical portion tubular where it joins 1-Cu, r-m nebulous, 2M+Cu tubular, 1-M tubular and 1-Cu spectral, with three hamuli, not equidistant, basal hamulus separate from other two.
Metasoma. 3.96 x length of mesosoma; tergites punctulate; aedeagus about same length as basiparameres.
Female. Unknown
Etymology. The species is named after the sclerophyllous scrubland (maquis minier) of Grand Terre, New Caledonia in which the type specimen was caught.
Comments. With a body length of 25.7 mm, G. maquis sp. nov. is much larger than the other two New Caledonian species, both of which are less than 12 mm in length. Of the three New Caledonian species, G. maquis is the only species with a more or less complete hind wing venation (Fig. 3). Gasteruption maquis can also be distinguished by the tubular portion of the fore wing vein 2-M ending with a small node, whereas in the other two species (Figs 2, 4), the node is absent.
