Key to Taiwanese species of Aulacidae

1. Occipital margin with a very wide and deep median emargination, most obvious in dorsal or dorso-ventral view, thus occipital carina interrupted or weakened medially ( Figs 1C , 3C )....................................................... 2

– Occipital margin without a median emargination, occipital carina not interrupted or weakened medially ( Figs 2D , 4C )..... 3

2. 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 ).................................................................. Pristaulacus karinulus Smith

– Head, from above, with gena moderately developed, 0.6–0.7 × eye length ( Fig. 4B ); fore wing with basal half hyaline ( Fig. 4A ); ovipositor 1.8 × longer than fore wing; setae of head and mesosoma golden ( Figs 4A, 4B, 4C, 4D )................................................................................................ Pristaulacus rufipes Enderlein
