Key to species of Aotearoazeus

1. Mesopleuron smooth and shining. Foveate groove deep and long, extending from anterior end to lower hind corner of mesopleuron ( Fig. 54 ). Clypeus about twice as broad as long ( Fig. 53 ). Basal keel and transverse carina of propodeum with short adjacent wrinkles ( Fig. 55 ). Ovipositor very robust, short, and strongly upcurved, its sheath 0.2–0.3× as long as hind tibia ( Fig. 57 )............................................................................... A. probles sp. nov.

- Mesopleuron granulate, dull. Foveate groove absent or weak and short ( Figs 40 , 48 ). Clypeus wider, at least 2.4× as broad as long ( Figs 39 , 46 ). Basal keel and transverse carina of propodeum without adjacent wrinkles. Ovipositor much longer, weakly upcurved, its sheath 0.9–1.2× as long as hind tibia............................................................ 2

2. Glymma weak, situated near centre of first tergite ( Fig. 40 ). Malar space about 0.7× as long as basal mandibular width ( Fig. 38 ). Flagellum with 25–27 flagellomeres ( Fig. 38 ). Hind leg dark brown with only trochanters pale ( Fig. 42 ). Second tergite almost twice as long as anteriorly broad. Ovipositor with shallow dorsal subapical depression ( Fig. 43 ), its sheath slightly shorter than hind tibia................................................................. A. bullivantus sp. nov.

- Glymma deep, situated in basal 0.3–0.4 of first tergite ( Fig. 49 ). Malar space 1.0–1.2× as long as basal mandibular width ( Fig. 45 ). Flagellum with 21–24 flagellomeres ( Fig. 45 ). Hind leg reddish brown with only coxa darkened ( Fig. 50 ). Second tergite 1.1–1.5× as long as anteriorly broad. Ovipositor with deep and narrow dorsal subapical notch ( Fig. 51 ), its sheath somewhat longer than hind tibia...................................................................
