Aulacidae are parasitoids of wood-boring larvae of Hymenoptera and Coleoptera, known in all zoogeographic regions of the World, except Antarctic. Two aulacids, Pristaulacus compressus (Spinola, 1808) and the rare Pristaulacus mourguesi Maneval, 1935, have been recently collected from Iran, the latter being a new record. Based on available data, the Iranian aulacid fauna includes five species within a single genus, Pristaulacus
Pristaulacus , Western Iran, wood-boring, parasitoid, illustrated key
The aulacid wasps, Aulacidae Shuckard, 1842 are endoparasitoids of wood-boring larvae Coleoptera (Cerambycidae and Buprestidae) and Hymenoptera (Xiphydriidae). The family Aulacidae is small distinct family in the superfamily Evanioidea. This family includes 262 extant species grouped within only two genera, Aulacus Jurine, 1807 with 83 species and Pristaulacus Kieffer, 1900 (including the former Panaulix Benoit, 1984), with 177 species (
Some evidence support strongly a close relationship between Aulacidae and Gasteruptiidae and each group are currently considered as distinct families (

The specimens examined in the present paper have been recently collected using a modified Malaise-trap (Funnel-Townes Style, B. Motamedinia, unpublished: BM-MTF-TS) placed in various localities of Kermanshah province (Western part of Iran), as well as in Eastern provinces (Fig.
Specimens were examined under a Nikon® SMZ645 stereomicroscope (Nikon® Inc., Japan). Illustrations of taxonomically important body parts were taken using a Canon® EOS 700D (Canon® Inc., Japan), a simple light source with halogen lamp (manual) and 2× lenses mounted on Hund® Stereomicroscope (Wetzlar Inc., Germany). Multiple images were subsequently processed in Zerene StackerTM version 1.04 software and post processed in Adobe Photoshop® CS6. The images in the illustrated key were prepared by the second author using voucher specimens already deposited in his private collection. Morphological terminology follows
Measurements were done with a micro-ruler. Morphometric ratios were measured in tpsDig ver. 2.05 (

P. galitae is a medium-sized species with a body length of 8.0–11.2 mm (excluding ovipositor), fore wing length 4.5–7.8 mm. It is distinguished by the combination of the following features: shape of the head, with rounded profile of temple, occipital carina moderately wide (0.5× OD), one anterior tooth-like process on each side of latero-ventral margin of pronotum, ovipositor length 1.0–1.2× fore wing length.

P. gloriator is a medium to moderately large-sized species with a body length of 10.2–15.0 mm (excluding ovipositor), fore wing length 8.2–11.8 mm. It can be easily identified by the shape of the head with a narrow cerciniform occipital carina (width 0.2× OD), a rugulose-carinulate frons, latero-ventral margin of pronotum rounded without tooth-like processes, four tooth-like processes on the inner margin of tarsal claw, and light yellow tarsi.
This species was reared from Paraclytus reitteri (Ganglbauer, 1881) (Coleoptera, Cerambycidae) feeding on alder, Alnus sp. The reared beetle is polyphagous in deciduous trees i.e. Acer, Alnus, Carpinus and Quercus (

Unknown (
This species was previously recorded only from Europe (
The number of Iranian Aulacidae is raised to five, all within a single genus (Pristaulacus). All these species have been collected in Northern and Northwestern (forest habitat) regions, except P. compressus, which is recorded from Southern (subdesertic habitat) region.
The new specimens have been collected in Zagros forests, which have an area of about 6 million hectares (3.5 percent of Iran), located in the west of Iran with a semi-arid to temperate climate. This wide territory is also referred to as western oak forests (oak-woodland), due to the dominancy of oak species (Quercus spp.). The species composition of the woodland vegetation depends on the climatic conditions (
The five species reported in this paper are distributed only in the Western part of the Palearctic region. The results of the present study clearly show the improved efficiency of modern collecting methods for Hymenoptera that are rarely collected with most conventional methods. In addition, the best collecting period seems to be June and this is consistent with those reported in
Although the research suggests a higher number of species in the Western territories of Iran we predict that the Eastern and Southern parts should also be quite species-rich. Further investigation, especially in poorly collected regions will probably increase the number of known species (
