Head, in dorsal view, with gena regularly rounded and moderately convergent behind eye (Fig. 1C); ovipositor length 1.1–1.3 × fore wing length....................................................... Pristaulacus comptipennis Enderlein – Head, in dorsal view, with gena almost straight and strongly convergent behind eye (Fig. 3C); ovipositor length slightly less fore wing length............................................................. Pristaulacus lanyuensis sp. nov. 3. Head, from above, with gena well developed, 0.8–0.9 × eye length (Fig. 2D); fore wing in basal half largely spotted with irregular dark marks (Fig. 2A); ovipositor shorter than fore wing length (Figs 2A); setae of head and mesosoma whitish (Figs 2C, 2D, 2E)..................................................................
