A new species of oak gallwasp, Andricus rosieae (Hymenoptera: Cynipidae: Cynipini) is described from Iran. This species is known only from asexual females and induce galls on the acorns of Quercus infectoria. Data on the diagnosis, distribution and biology of the new species are given. Keywords: Cynipini, Andricus, taxonomy, Iran, distribution, new species. Introduction Only 36 species of oak gallwasps (Hymenoptera, Cynipidae, Cynipini) were recorded in the first work on cynipid fauna of Iran (Chodjai 1980). Since then, a number of works have been pub- lished on the oak gallwasp fauna of Iran with de- scriptions of new species (Melika & Stone 2001, Melika et al. 2004, Azizkhani et al. 2006, Tavakoli et al. 2008, Pénzes et al. 2009). In the recent mono- graph on cynipid fauna of Iran, 77 species of oak gallwasps were listed (Sadeghi et al. 2010). Iran lies at the eastern limit of the Western Palaearctic, and recent surveys confirm that its cynipid fauna includes widespread Western Palaearctic species such as Andricus kollari (Hartig) and Cynips quercusfolii (Linnaeus); species limited to the eastern part of this region such as the insana form of Andricus quercustozae (Bosc), Andricus megalucidus Melika, Stone, Sadeghi & Pujade- Villar and Aphelonyx persica Melika, Stone, Sadeghi & Pujade-Villar (Melika et al. 2004); and taxa cur- rently unknown from Turkey that may represent Iranian endemics, including Andricus stonei Me- lika, Tavakoli & Sadeghi, Dryocosmus tavakolii Me- lika, Stone & Azizkhani and Dryocosmus mikoi Me- lika, Tavakoli, Stone & Azizkhani (Azizkhani et al. 2006) and 14 other recently described species (Ta- vakoli et al. 2008). Here we describe another endemic from Iran, Andricus rosieae n. sp., known to induce galls on acorns of Quercus infectoria Olivier (Fagaceae). Materials and Methods We follow the current terminology of morphological structures (Liljeblad & Ronquist 1998, Melika 2006). Ab- breviations for fore wing venation follow Ronquist & Nordlander (1989), and cuticular surface terminology fol- lows that of Harris (1979). Measurements and abbrevia- tions used here include: F1–F12: 1st and subsequent flag- ellomeres; POL: post-ocellar distance, the distance be- tween the inner margins of the posterior ocelli; OOL: ocel- lar-ocular distance, the distance from the outer edge of a posterior ocellus to the inner margin of the compound eye; and LOL: the distance between lateral and frontal ocelli. The width of the forewing radial cell is measured from the margin of the wing to the Rs vein. Images of wasp anatomy were produced with a digi- tal Nikon Coolpix 4500 camera attached to a Leica DMLB compound microscope, followed by processing using CombineZP (Alan Hadley) and Adobe Photoshop 6.0. Gall images were taken by M. Tavakoli. Results Andricus rosieae Melika & Stone n. sp. (Figs 1–3) Type material: HOLOTYPE female: IRAN, Lorestan, Ghelaei, ex. Q. infectoria, Lor385, coll. M.
