POL 0.7 × OD; OOL 2.5 × OD. Face 1.6 × as wide as high, with very sparse setae laterally, almost entirely smooth; inner margins of eyes subparallel. Clypeus 2.0 × as wide as high, slightly concave ventrally. Paraclypeal fovea small, not reaching half distance between clypeus and inner border of eye. Mandible almost parallel-sided, 1.1 × as long as its maximum width; its middle tooth wide and rather short, partly directed below, lower tooth evenly curved on outside margin. Antenna with 19 antennomeres, 1.1 × as long as body. Scape 1.5 × as long as pedicel. First flagellomere 3.2 × as long as its maximum width, 1.3 × as long as second flagellomere. Second to 10th flagellomeres 2.3–2.4 ×, 11th to 16th flagellomeres 2.0 ×, and 17th (apical) flagellomere 3.0 × as long as their maximum width. Mesosoma. In lateral view 1.1 × as long as high. Mesoscutum (dorsal view) about as long as its maximum width, smooth, sparsely setose. Notauli present only on vertical anterior surface of mesoscutum. Prescutellar depression (scutellar sulcus) smooth, only with median carina, 0.7 × as long as its maximum width. Precoxal sulcus wide, oblique, almost smooth, not reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow smooth. Propodeum smooth, with complete median longitudinal carina, with short emerging carinae and not reaching propodeal edges. Propodeal spiracles very small, its diameter 0.2 × distance from spiracle to anterior margin of propodeum. Wings. Length of fore wing 2.6 × its maximum width.

Hind tibia distinctly widened to apex, 7.7 × as long as its maximum subapical width, 1.1 × as long as hind tarsus. First tarsomere of hind tarsus 1.5 × as long as second tarsomere. Metasoma. First tergite weakly evenly widened towards apex, 2.0 × as long as its apical width, striate. Ovipositor 1.3 × as long as first tergite, 0.4 × as long as metasoma, as long as hind femur. Colour. Body, head, antennal segments and pterostigma dark brown. Mandible and legs light brown. First metasomal tergite similar colour to second and third tergites. Wings almost hyaline. Variation. Body length 1.5–1.7 mm, fore wing 1.6–1.9 mm, hind wing 1.1–1.3 mm. Antenna with 16–19 antennomeres. First flagellomere 3.0–3.2 × as long as its maximum width. Mandible 1.1–1.2 × as long as its maximum width. Hind femur 4.0–4.4 × as long as its maximum width. Legs light brown to brown. Otherwise similar to holotype. Male. Unknown. Etymology. The name is referring to the inhabitants of Papua New Guinea, “Papú”. Comparative diagnosis. This new species is similar to Australian Orthostigma (Papuastigma) gallowagi Wharton; differences between both species are described under the latter species and in the key below. Distribution. Papua New Guinea.
