Key to species of Gauldiana

1. Clypeus subtriangular, with lower lateral margin conspicuously concave ( Fig. 105 View FIGURES 104–109 ). Mandible distinctly twisted. Female with first tergite rather strongly depressed, transversely oval in cross-section. Antenna entirely orange; flagellum weakly clavate, with about 19–21 flagellomeres, and the subapical flagellomere transverse ( Fig. 104 View FIGURES 104–109 ). Head black with yellowish clypeus and orange marks near base of mandible ( Figs 105, 106 View FIGURES 104–109 ); mesosoma orange with three black marks on mesoscutum ( Figs 37 View FIGURES 32–37 , 106 View FIGURES 104–109 ); metasoma behind first tergite brownish yellow ( Figs 37 View FIGURES 32–37 , 109 View FIGURES 104–109 ). Relatively large with body length about 5.0 mm and fore wing length 3.8–4.1 mm .................................................................... G. triangulata sp. nov.

- Clypeus lenticular ( Figs 89 View FIGURES 88–92 , 94 View FIGURES 93–97 ). Mandible not twisted. First tergite more or less round in cross-section. Antenna entirely black, or pale basally and gradually darkening towards apex; flagellum filiform or clavate, usually with lesser number of flagellomeres ( Figs 88 View FIGURES 88–92 , 95 View FIGURES 93–97 , 99–101 View FIGURES 98–103 ). Mesoscutum either orange or black, without clearly defined black anteromedian and lateral marks. Head orange to black. Small to medium-sized with body length 2.3–3.5 mm and fore wing length 2.1–3.0 mm............ 2

2. Mesosoma more or less entirely orange, sometimes with a weak reddish brown marking ( Figs 29 View FIGURES 27–31 , 34 View FIGURES 32–37 ). Fore wing with vein 2mcu interstitial or slightly postfurcal ( Fig. 19 View FIGURES 16–20 ). Ovipositor weakly upcurved in basal 0.8 and strongly upcurved apically ( Figs 29 View FIGURES 27–31 , 34 View FIGURES 32–37 )................................................................................................. 3

- Mesosoma dark reddish brown to black, sometimes with reddish orange markings on pronotum, mesoscutum and mesopleuron ( Figs 30–33, 35, 36 View FIGURES 27–31 View FIGURES 32–37 ). Fore wing with vein 2m-cu interstitial to distinctly postfurcal. Ovipositor evenly upcurved over its entire length or strongly upcurved apically....................................................................... 4

- Head with at least lower face and genae orange or orange-brown, usually entire eye orbits orange ( Fig. 29 View FIGURES 27–31 ). Mesosoma orange with reddish brown markings ( Fig. 29 View FIGURES 27–31 ). Legs yellow but hind coxa usually darkened. Flagellum slightly clavate apically, with 16–17 flagellomeres ( Fig. 88 View FIGURES 88–92 ). Ovipositor sheath about twice as long as hind tibia.................... G. arantia sp. nov.

4. Antenna dark brown or black, flagellum short, distinctly clavate, with 13–14 flagellomeres ( Fig. 101 View FIGURES 98–103 ). Ovipositor strongly and evenly upcurved in apical half, its sheath about as long as hind tibia ( Fig. 103 View FIGURES 98–103 ). Malar space short, 0.4–0.5× basal mandibular width ( Fig. 101 View FIGURES 98–103 )......................................................................... G. minuta sp. nov.

- Antenna sometimes pale basally, flagellum longer, filiform or clavate, with 15–19 flagellomeres ( Figs 95 View FIGURES 93–97 , 99, 100 View FIGURES 98–103 ). Ovipositor weakly upcurved, sometimes with apex strongly upcurved, its sheath usually much longer than hind tibia. Malar space usually>0.5× basal mandibular width............................................................................ 5

5. Metasoma behind first tergite brown ( Fig. 32 View FIGURES 32–37 ). Fore wing with pterostigma pale brown ( Fig. 32 View FIGURES 32–37 ). Antenna uniformly brown or black ( Fig. 100 View FIGURES 98–103 ). Ovipositor sheath 1.7–1.85× as long as hind tibia................................ G. kaweka sp. nov.
