Kiwi earlyi Khalaim & Ward , sp. nov.

( Figs 9 , 24–27, 61)

Comparison. The new species is similar to K. canterberus from which it differs by yellow-orange or red-brown markings on mesosoma ( Fig. 9 ), strong foveate groove of mesopleuron with coarse transverse wrinkles ( Fig. 26 ) and slender ovipositor ( Fig. 27 ). Kiwi earlyi is also characterized by very slender flagellum of antenna ( Fig. 24 ).

Description. Female. Body length 2.5 mm. Fore wing length 2.25 mm.

Head in dorsal view roundly tapered behind eyes, with gena 0.8× as long as eye width. Head without distinct punctures; clypeus smooth; face and frons shallowly granulate, weakly shining; vertex very shallowly granulate to smooth; gena smooth and shining. Clypeus lenticular, weakly convex, with lower margin laterally somewhat impressed. Flagellum very slender, filiform, with 15–18 flagellomeres (17 in holotype); sub-basal flagellomeres 2.3–2.6× and subapical flagellomeres 1.4–1.6× as long as broad. Mandible with upper tooth longer than the lower. Malar space about as long as basal mandibular width.

Mesosoma granulate, impunctate, dull; mesopleuron ventrally and in upper part (above foveate groove) very shallowly granulate, sometimes almost smooth. Notaulus with strong longitudinal wrinkle on anterolateral side of mesoscutum. Foveate groove deep and long, weakly oblique, with coarse transverse wrinkles ( Fig. 26 ). Propodeal spiracle separated from pleural carina by about 1.0–1.5× diameter of spiracle. Propodeum mediodorsally with weak longitudinal wrinkles which are sometimes completely obliterated; basal part as long as apical area; transverse carina well developed; apical area widely rounded anteriorly; apical longitudinal carinae distinct posteriorly and usually obliterated anteriorly. Fore wing with vein 2m-cu distinctly postfurcal, unpigmented in front half or more, with posterior end distinct.

First tergite slender, 3.6–3.8× as long as posteriorly broad, in lateral view with upper margin straight or weakly convex in anterior 0.7 and arcuate in posterior 10.3; petiole longitudinally striate, postpetiole granulate or sometimes partly striate over granulation. Glymma weak (sometimes indistinct), situated in centre or slightly behind centre of first tergite; furrow between glymma and ventral part of postpetiole absent. Second tergite 1.2× as long as anteriorly broad. Thyridial depression very shallow, about 1.5× as long as broad. Ovipositor slender, weakly upcurved, with shallow dorsal subapical depression ( Fig. 27 ); sheath 1.1–1.6× (1.1× in holotype) as long as hind tibia.

Head brownish black, clypeus yellow except extreme upper margin. Mandible (teeth dark red), scape and pedicel of antenna, palpi and tegula brownish yellow. Flagellum dark brown to black, usually paler basally. Mesosoma dark reddish brown to black; propleuron, pronotum, mesoscutum, scutellum and upper front part of mesopleuron (sometimes also below foveate groove) orange-brown; mesoscutum with three more or less distinct longitudinal blackish stripes. Pterostigma brown. Legs brownish yellow, hind coxa weakly darkened with brown, all tarsi more or less infuscate. First tergite dark reddish brown. Metasoma posterior to first tergite yellow-brown to dark reddish brown.

Male. Unknown.

Etymology. The species is named after John Early for his contribution to New Zealand entomology.
