F.: A new species of Pristaulacus Kieffer, 1900from Laos (Hymenoptera: Aulacidae). Abstract: A new species, belonging to the recently revised Pristaulacus comptipennis species-group, P. harisi Turrisi, sp. nov. from Laos (Ventiane Province, Ban Van Eue) is described, illustrated and compared with most related species. Keywords: Hymenoptera, Aulacidae, Pristaulacus harisi, new species, Laos. Introduction Aulacidae comprises 242 extant species belonging to two genera (Turrisi et al. 2009 and subsequent additions, e.g., Turrisi 2013; Turrisi and Madl 2013; Watanabe et al. 2013), Aulacus Jurine, 1807, with 76 species and Pristaulacus Kieffer, 1900 (including the former Panaulix Benoit, 1984), with 166 species. The number of described species has been strikingly increased since the publication of the World Aulacidae catalogue (Smith 2001), which listed around 150 species, and has stimulated a number of investigations, especially of poorly known regions (Smith 2005a, 2005b, 2008; He et al. 2002; Jennings et al. 2004a, 2004b, 2004c; Turrisi 2004, 2005, 2006, 2007, 2011; Jennings and Austin 2006; Sun and Sheng 2007a, 2007b; Turrisi et al. 2009; Smith and Vilela de Carvalho 2010; Turrisi and Konishi 2011; Turrisi and Smith 2011; Turrisi and Watanabe 2011; Turrisi 2013; Turrisi and Madl 2013; Watanabe et al. 2013). Both genera are represented in all zoogeographic regions, except Antarctica, and Aulacus is not known from the Afrotropics (Kieffer 1912; Hedicke 1939; Smith 2001; Turrisi 2004; Turrisi et al. 2009). Aulacidae are koinobiont endoparasitoids of wood-boring larvae of Hymenoptera and Coleoptera (Skinner and Thompson 1960; Deyrup 1984; Jennings and Austin 2004). Hosts are larval Xiphydriidae (Hymenoptera), Buprestidae (Coleoptera) and, more frequently, Cerambycidae (Coleoptera) (Barriga 1990; Visitpanich 1994; Turrisi 1999, 2004, 2007; Smith 2001; Jennings and Austin 2004). The Pristaulacus comptipennis species-group is endemic to a number of countries of eastern and south-eastern Asia: Japan, Korea and China, with a limited number of species, and Thailand, Laos and Vietnam, with a significantly greater number of taxa, most of which have been recently described (Turrisi and Smith 2011; Turrisi and Madl 2013). This species-group was shown to be monophyletic in the phylogenetic study by T urrisi et al. (2009) and is characterized by the deep occipital emargination of the head, most obvious in dorsal view, whereas the posterior margin of the head is straight or
