Kiwi waitakerus Khalaim & Ward  , sp. nov.

( Figs 4View FIGURES 1–6, 14View FIGURES 11–14, 44, 45View FIGURES 43–45, 64)

Comparison. The new species may easily be distinguished from other species of Kiwi  by completely lacking vein 2m-cu in the fore wing ( Fig. 4View FIGURES 1–6). It is similar to K. oreteus  and K. ruzelus  but differs from these two species by granulate gena ( Fig. 44View FIGURES 43–45), less slender antennal flagellum and longer ovipositor. It also differs from K. ruzelus  by shorter gena, weaker foveate groove of mesopleuron ( Fig. 44View FIGURES 43–45), longer tergites 1 and 2, and by shape of the ovipositor ( Fig. 45View FIGURES 43–45).

Description. Female. Body length 2.1 mm. Fore wing length 1.9 mm.

Head in dorsal view strongly rounded and tapered behind eyes, with gena 0.55–0.6× as long as eye width. Head impunctate, granulate, dull; clypeus almost entirely smooth, slightly scabrous near upper margin, usually with a few fine punctures in lower part; gena sometimes very shallowly granulate, weakly shining. Vertex mediodorsally impressed. Clypeus lenticular, weakly convex, with lower margin somewhat truncated. Flagellum filiform or slightly tapered towards apex, moderately slender, usually with 15–16 flagellomeres (15 in holotype), in small specimens sometimes with 13–14 flagellomeres; flagellomeres 2–4 about 1.6–2.0× and subapical flagellomeres 1.2–1.4× as long as broad. Mandible slender, with upper tooth somewhat longer than the lower. Malar space 0.6–0.8× as long as basal mandibular width.

Mesosoma granulate, impunctate, dull; mesopleuron in upper posterior part very shallowly granulate, sometimes almost smooth. Notaulus with a strong longitudinal wrinkle on anterolateral side of mesoscutum. Foveate groove short and thin, oblique, situated in front half of mesopleuron, not reaching epicnemial carina anteriorly, with fine transverse wrinkles ( Fig. 44View FIGURES 43–45). Propodeal spiracle separated from pleural carina by 1.5–2.0× diameter of spiracle. Propodeum mediodorsally granulate or with one or two longitudinal wrinkles; basal part 0.6–0.8× (rarely almost 1.0×) as long as apical area; transverse carina well developed; apical area widely rounded anteriorly; apical longitudinal carinae complete. Fore wing with vein 2m-cu completely absent ( Fig. 4View FIGURES 1–6), in larger specimens the extreme hind end sometimes discernible as a vestige.

First tergite very slender, about 4.6× as long as posteriorly broad, in lateral view straight or weakly arcuate in basal 0.7, strongly arcuate in apical 0.3, usually with a slight concavity in apical 0.6–0.7 ( Fig. 42View FIGURES 38–42); petiole longitudinally striate; postpetiole granulate, often with slight striae over granulation. Glymma small, situated in mid of tergite or slightly behind middle, joining by furrow to ventral part of postpetiole. Second tergite 1.3–1.5× as long as anteriorly broad. Thyridial depression well delimited, about 1.5× as long as broad. Ovipositor with moderately deep dorsal subapical depression ( Fig. 45View FIGURES 43–45); sheath 1.2–1.8× as long as hind tibia (1.8× in holotype).

Head, mesosoma and metasoma brown to dark brown; mouthparts, mandible (teeth red), scape and pedicel of antenna yellow; lower 2/3 of clypeus pale brown. Tegula yellow or brownish. Pterostigma brown. Legs yellow to yellowish brown; hind leg with coxa darkened with brown, tarsus infuscate, and sometimes femur and tibia also brownish.

Male. Similar to female.

Variation. The species is morphologically rather variable (e.g. ovipositor sheath varied from 1.2 to 1.8× length of hind tibia, more than in any other New Zealand tersilochine species), but this taxon is clearly distinguished from its congeners by completely lacking vein 2m-cu (Fig. 4).

Etymology. The species is named after the type locality, the Waitakere Ranges, west of Auckland.
