Aotearoazeus probles Khalaim & Ward , sp. nov.

( Figs 11 , 22 , 52–58 )

Description. Female. Body length 4.0 mm. Fore wing length 3.4 mm.

Head, in dorsal view, with genae almost 0.8× as long as eye width. Clypeus narrow, about twice as broad as long ( Fig. 53 ). Malar space about as long as basal mandibular width. Mandible with upper tooth somewhat longer than lower tooth. Flagellum filiform or slightly tapered towards apex, basally slender, with 23–25 flagellomeres (25 in holotype) ( Fig. 52 ). Head very finely and shallowly granulate (genae almost smooth), weakly shining.

Mesosoma predominantly finely granulate, weakly shining; mesopleuron smooth and shining ( Fig. 54 ); propodeum coriaceous or uneven. Notaulus long, weakly to strongly impressed, with irregular wrinkles anterolaterally. Foveate groove deep and long, upcurved anteriorly, extending from anterior margin to lower hind corner of mesopleuron, with distinct transverse wrinkles ( Fig. 54 ). Propodeum mediodorsally slightly impressed, with more or less distinct basal keel which is about 0.8× as long as apical area ( Fig. 55 ). Transverse carina of propodeum strong medially and weak or evanescent laterally. Basal keel and transverse carina with numerous adjacent fine wrinkles ( Fig. 55 ). Apical area somewhat convex, widely rounded anteriorly. Apical longitudinal carinae weak or absent. Propodeal spiracle separated from pleural carina by 2.0–3.0× diameter of spiracle.

Fore wing ( Fig. 11 ) with vein R1 not reaching apex of the wing. Veins Rs+2 r and Rs meeting at 85–90°. Vein 2mcu strongly antefurcal, vein 2rs-m short and thick. Postnervulus intercepted in its lower 0.3. Hind wing with vein cu1&cu-a somewhat reclivous. Legs slender, hind femur about 5.6× as long as broad and 0.8× as long as tibia ( Fig. 56 ).

Metasoma with first tergite about 3.8× as long as apically broad, petiole coraceous dorsally and striate laterally, postpetiole predominantly smooth, dorsally partly striate. Glymma weak to rather deep, situated in basal 0.45–0.55 of tergite ( Fig. 54 ). Second tergite about 1.8× as long as anteriorly broad. Ovipositor very short, robust and strongly upcurved, with rather deep dorsal subapical depression in its apical 0.3–0.4 ( Fig. 57 ); sheath 0.2–0.3× as long as hind tibia.

Head, mesosoma and first tergite black; lower 0.5–0.7 of clypeus brownish. Mandible (teeth dark red or blackish) and palpi yellow. Antenna dark brown, scapus and pedicel usually yellowish or pale brown. Tegula yellow. Pterostigma brown. Legs reddish brown; hind coxa brownish black; hind tibia and tarsus fuscous (mid tarsus sometimes also fuscous). Metasoma behind first tergite predominantly dark brown, tergite 2 with broad posterior yellowish band, sometimes metasoma extensively yellowish brown behind mid of tergite 3.

Male. Flagellum with 25–28 flagellomeres.

Etymology. Named after its long foveate groove which is very similar to that in the genus Probles Förster.
