(Figs 1, 7, 18–21, 59)
Comparison. The new species is similar to K. gauldi as both have robust antennal flagellum with subapical flagellomeres more or less quadrate (Figs 18, 28) and granulate gena, but differs from this species by longer malar space (Fig. 18), shape and length of the ovipositor (Fig. 21) and darker colouration of mesosoma (Fig. 19).
Description. Female. Body length 3.5 mm. Fore wing length 2.25 mm.
Head in dorsal view roundly tapered behind eyes, with gena almost 0.9× as long as eye width. Head granulate, dull, without distinct punctures; clypeus impunctate or with rare punctures in upper and/or lower parts, entirely shallowly granulate or smooth in lower part; granulation on gena usually shallower. Clypeus lenticular, weakly convex, with lower margin sometimes slightly truncated. Flagellum robust, slightly widened at apex, with 15–19 flagellomeres (18 in holotype); basal and mid flagellomeres weakly elongate and subapical flagellomeres transverse (Fig. 18). Mandible slender, with upper tooth somewhat longer than the lower. Malar space 1.1–1.2× as long as basal mandibular width (Fig. 18).
Mesosoma granulate, almost impunctate, dull; mesopleuron centrally (above foveate groove) and ventrally with granulation usually very shallow and sometimes with fine sparse punctures. Notaulus with a strong longitudinal wrinkle on anterolateral side of mesoscutum. Foveate groove moderately broad, weakly oblique, extending in front 2/3 of mesopleuron and usually reaching epicnemial carina anteriorly, with distinct transverse wrinkles (Fig. 19). Propodeal spiracle separated from pleural carina by 0.5–1.5× diameter of spiracle. Propodeum (Fig. 20) mediodorsally usually with one or several weak longitudinal wrinkles; basal part 0.8–1.0× as long as apical area; transverse carina well developed, usually with short adjacent wrinkles; apical area widely rounded anteriorly; apical longitudinal carinae complete. Fore wing with vein 2m-cu interstitial or slightly antefurcal, anteriorly unpigmented, distinct posteriorly. Vein R1 short, not reaching apex of the wing.
First tergite robust, 2.4–2.8× as long as posteriorly broad, trapeziform in cross-section in basal half (with strong dorsolateral longitudinal carinae), with dorsal side flat, in lateral view weakly arcuate or straight in basal 0.5–0.6 and arcuate in apical 0.4–0.5 (Fig. 19); petiole longitudinally striate laterally and shallowly sculptured dorsally; postpetiole weakly granulate. Glymma small, situated in centre or slightly before centre of tergite, furrow between glymma and ventral part of postpetiole distinct or sometimes obliterated. Second tergite slightly transverse, about 0.9× as long as anteriorly broad. Thyridial depression 1.0–1.5× as long as broad. Ovipositor weakly and evenly upcurved, with weak dorsal subapical depression and more or less developed rounded teeth before and behind this depression (Fig. 21); sheath 1.5–1.9× (1.9× in holotype) as long as hind tibia Head and mesosoma black, sometimes with slight brownish tinge; clypeus brownish yellow or reddish brown in lower 0.6–0.8. Mandible brownish yellow with teeth dark red or reddish black. Mouthparts yellow, maxillary and labial palps brownish. Antenna dark brown or black. Tegula brownish yellow. Pterostigma brown to dark brown. Legs brownish yellow to yellow-brown, hind coxa blackish, sometimes hind femur and tibia also darkened; tarsi fuscous. First metasomal segment brownish black to black. Metasoma posterior to first tergite yellow-brown ventrally to dark brown dorsally.
.
Male. Flagellum slenderer, with 18–19 flagellomeres; malar space 0.9× as long as basal mandibular width; metasomal tergites slenderer; otherwise similar to female.
Variation. Two females from Coronet Pk (OL) and Pouakai Ra (TK) are paler than other specimens, with mesosoma reddish brown rather than black (Fig. 18). One male from Old Man Range (CO, deposited in ZISP) possesses clypeus entirely black (probably abnormally) and second tergite depressed, similar to that in the genus Aotearoazeus Khalaim & Ward.
Etymology. The species is named after Barbara Barratt for her contribution to New Zealand entomology.
