( Figs 6View FIGURES 1–6, 17, 50–52View FIGURES 46–51View FIGURES 52–57, 66)

Comparison. The new species is very similar to Z. abdominosus  but differs from this species by darker colouration of head ( Figs 50–52View FIGURES 46–51View FIGURES 52–57), more slender antennal flagellum ( Fig. 50View FIGURES 46–51), longer distance between propodeal spiracle and pleural carina ( Fig. 52View FIGURES 52–57) and strongly upcurved ovipositor apex.

Description. Female. Body length 2.9 mm. Fore wing length 2.45 mm. Flagellum weakly clavate, with 15–16 flagellomeres (15 in holotype); subbasal flagellomeres 2.0–2.5× and subapical flagellomere 1.2–1.3× as long as broad. Foveate groove distinct, with short transverse wrinkles, long and usually reaching front margin of mesopleuron anteriorly ( Fig. 52View FIGURES 52–57). Propodeal spiracle separated from pleural carina by 1.0–2.0× diameter of spiracle. Fore wing with vein 2m-cu interstitial or slightly postfurcal ( Fig. 6View FIGURES 1–6). Ovipositor strongly upcurved apically ( Fig. 17View FIGURES 15–17); sheath 1.5–2.0× (2.0× in holotype) as long as hind tibia.

Head dark brown or brownish black; clypeus and lower part of gena next to mandible yellow; face usually yellowish or pale reddish brown ( Figs 50–52View FIGURES 46–51View FIGURES 52–57). Mandible yellow, teeth reddish black. Scape and pedicel of antenna yellow; flagellum entirely black, at most slightly paler basally ( Fig. 50View FIGURES 46–51). Mesosoma orange or reddish orange, propodeum and metapleuron usually slightly darker ( Fig. 55View FIGURES 52–57). Pterostigma brown. Legs yellow, hind coxa usually orangish, hind tibia and tarsus sometimes infuscate. Metasoma posterior to second tergite brownish or blackish dorsally.

Male. Flagellum very slender, filiform, with 16–18 flagellomeres; metasoma uniformly brown or dark brown. Otherwise similar to female.

Etymology. The new species is named after Stephen Thorpe, a New Zealand entomologist, and collector of a number of tersilochine specimens included in this study.
