Genus Pristaulacus Kieffer 1900

Synonymies. See Turrisi et al. (2009: 53).

The genus Pristaulacus has been redefined by Turrisi et al. (2009) within a cladistic framework and is represented in all zoogeographic regions excepting Antarctica. It can be distinguished from Aulacus by the following combination of characters: occipital carina present ( Figs. 6, 7 , 23 ) (absent in Aulacus ); frons not sculptured above antennal sockets ( Figs. 5, 7 ) (sculptured in Aulacus ); tarsal claws with three or four tooth-like processes along inner margin ( Fig. 15 ) (with only one weak basal process in Aulacus ); petiole slender, at least 2.5 times as long as wide ( Figs. 1 , 2 , 22 ) (at most 1.0 times as long as wide in Aulacus ) (Turrisi 2007; Turrisi et al. 2009).

The Japanese species of Pristaulacus can be distinguished by the following key, updated after Turrisi & Konishi (2011) and Turrisi & Watanabe (2011).
