(Figs 28, 82–87)
Comparison. Diaparsis zealandica differs from the Australian species by characters given in the key below.
1. Propodeum with basal part almost as long as apical area (Fig. 86); apical area anteriorly broadly rounded (Fig. 86). Flagellum very slender, with flagellomeres 2–4 more than 3.0× as long as broad (Fig. 82). Ovipositor with apex strongly upcurved (Fig. 87), its sheath about 3.0× as long as first tergite. New Zealand ................................ D. zealandica sp. nov.
- Propodeum with strong basal keel which is about 0.35× as long as apical area; apical area anteriorly roundly pointed. Flagellum less slender, flagellomeres 2–4 about twice as long as broad. Ovipositor weakly and gradually upcurved its entire length, with sheath 2.2× as long as first tergite. Australia ....................................... D. proterva Khalaim, 2008
Description. Female. Body length 4.3 mm. Fore wing length about 3.1 mm.
Head densely granulate, impunctate, strongly and roundly narrowed behind eyes in dorsal view, gena short (Fig. 83). Flagellum very slender, with 18–20 flagellomeres (Fig. 82); flagellomeres 2–3 more than 3.0×, subapical flagellomere about 1.5× as long as broad. Upper tooth of mandible longer than the lower. Malar space very long, about 1.3× as long as basal mandibular width. Clypeus smooth in lower part; very finely granulate and sparsely punctate in upper part. Face with weak prominence centrally.
Mesosoma densely granulate, impunctate or sometimes with very indistinct punctures on mesoscutum and mesopleuron (Figs 83, 85). Notaulus as sharp and strong wrinkle (Fig. 85). Foveate groove of mesopleuron situated in centre of mesopleuron, strongly oblique, rather shallow, with fine transverse wrinkles. Propodeum (Fig. 86) with basal part about as long as apical area; basal keel often partly or entirely indistinct and propodeum dorsally is more or less irregularly wrinkled; transverse carina strong; apical longitudinal carinae weak to well developed; apical area very broad, flat, widely rounded anteriorly. Propodeal spiracle separated from pleural carina by about 3.0× diameter of spiracle.
Fore wing with vein R1 not reaching apex of the wing. Vein 2m-cu weakly postfurcal. Vein 2rs-m thick, longer than abscissa of M between 2rs-m and 2m-cu. Postnervulus intercepted distinctly below its middle. Hind wing with vein cu1&cu-a somewhat reclivous. Legs very slender. Hind femur 5.2× as long as broad and 0.8× as long as tibia (Fig. 84). Hind leg with second trochanter fused with femur. Tarsal claws weakly curved, not pectinate.
First tergite of metasoma slender, 4.2× as long as posteriorly broad, round in cross-section centrally, smooth and shining, petiole weakly separated from postpetiole in dorsal view. Glymma absent. Second tergite 2.2× as long as broad anteriorly. Thyridial depression 2.0–3.0× as long as broad. Ovipositor with apex strongly upcurved, with very shallow dorsal subapical depression (Fig. 87); sheath about 3.0× as long as first tergite.
Body black. Clypeus yellow in its lower part and blackish in upper part. Mandible (except reddish teeth), palpi and tegula yellow. Antenna mostly black, yellow-brown basally. Pterostigma brown. Legs brownish yellow, hind and sometimes also mid coxa basally blackish, all tarsi infuscate. Metasoma behind first tergite yellow ventrally to dark brown dorsally, tergites mostly yellowish banded posteriorly.
