(Figs 1, 12–14)
Material examined. Holotype. ♀, " Papua: Fly River, Kiunga, 35 m, August, 1969 " " J & M Sedlacek " (BPBM).
Paratype. Papua New Guinea: 1♀, same data as holotype (BPBM).
FEMALE. Length. 13.0 (12.0–14.0) mm, excluding ovipositor.
Colour. Body and head black; antenna brown except scape light brown, fore and mid legs brown, hind leg darker brown except tarsus pale, ovipositor and sheath brown; metasoma black except T2 and T3 brown dorsally and T1–T5 brown laterally and ventrally; wings hyaline, fuscous spot on apical half of first submarginal cell, second submarginal cell and most of marginal cell of fore wing, this joined on holotype to form a continuous fuscous patch.
Head. 1.45 x wider than long in dorsal view (Fig. 12); face smooth with a few shallow punctures medially, pubescence long; weak subantennal groove; frons without lateral medial carina above toruli, smooth with a few shallow punctures medially, with long pubescence; vertex smooth, rugulose medially near occipital carina, with scattered long setae; gena weakly rugulose, with scattered long setae; posterior margin of head concave in dorsal view; occipital carina narrow; malar space 0.26 x eye height; clypeus 5.0 x as wide as high, margin sinuate, small medial process; distance from lateral ocellus to eye margin 1.08 (1.00–1.15) x distance between lateral ocelli (Fig. 12); scape 1.2 (1.0–1.4) x length pedicel; first flagellomere 1.42 (1.17–1.67) x as long as scape, 0.53 (0.47–0.58) x as long as second flagellomere.
Mesosoma. Propleuron smooth, pubescence long, ventro-lateral carina pronounced (Fig. 13); pronotum with angular process (Fig. 13), rugose punctate; mesoscutum in lateral view acute antero-dorsally, medial and lateral lobes coarsely strigate, with scattered long setae, admedial lines present; scutellum and axilla coarsely strigate; metapostnotum scrobiculate, posterior margin sinuate; mesepisternum rugose, with long pubescence; mesepimeron broad, carinate; metapleuron rugose, with long pubescence; propodeum coarsely rugose, posterior margin smooth; hind coxa smooth dorsally, pubescence long laterally, ovipositor guide on inner surface, somewhat distal, sloping slightly posteriorly (Fig. 14); hind trochanter imbricate, with scattered short setae; hind prefemur on hind leg present; hind femur imbricate, with short setae; hind tibia imbricate, pubescence short; hind femur 0.67 (0.66–0.68) x length hind tibia; hind tibia with ventro-apical pecten of short robust spines; hind tarsal segments 1–4 with ventro-apical pecten of short robust spines, segment 1, 3.75 (3.3–4.2) x length segment 2; segment 2, 1.75 (1.5–2.0) x length segment 3; segment 3, 0.64 (0.57–0.71) x length segment 4; segment 4, 0.57 x length segment 5; hind tarsal claw with 3 median teeth, 0.57 x length segment 5; fore wing vein 2-Rs+M short, second discal cell more or less quadrate, vein 2r-m absent, vein 3r-m complete, spectral medially; hind wing venation incomplete, veins R+Rs, M+Cu, Cu, absent, r-m and 2-M spectral, with 2 hamuli.
Metasoma. 1.3 (1.2–1.4) x length of mesosoma; T1 and T2 narrow when viewed dorsally, glabrous; ovipositor 9.7 (9.6–9.8) mm.
MALE. Unknown
Remarks. Pristaulacus kiunga is readily distinguished from the other New Guinean species, P. l a l o k i, by the angular process on the pronotum (Fig. 13) and the entirely black head lacking the broad cream-coloured stripe on the inner eye margin on the malar space, face, and frons.
This species is named after the holotype locality, Kiunga, Fly River, Papua New Guinea (Fig. 1). Nothing is known of its host biology.
