چکیده
This study was conducted on Cynipinae gall wasps in northern and central Zagros forests of Iran during 2015-17. The gall samples were collected from Acer monospessulanum (Aceraceae) at Qalayi rural district located at Lorestan province, western Iran in early May 2016. Then, they were reared in laboratory conditions and sexual forms of adult wasps emerged in late May of same year. The identified gall wasps specimens and their associated galls are retained in the collection of plant galls of Natural Recourses Research Center, Lorestan, Iran. This species were identified according to taxonomical keys as Pediaspis aceris and verified by George Melika (3rd author) based on the following characters; Female: body length 2.2-3 mm, the body and its appendages regularly colored in brown chestnut, wing vein distinct in dark brown, head with smoothly cobbled pattern, with uniformly scattered white hairs, antenna with 14 segments more or less half the body length. Male: body length 2.3-2.8 mm, similar to female in appearance as usually the whole body is brighter, antenna with 15 segments more longer and thinner than the females, the galls are seen as oval, spherical and / or the irregular forms with sponged solid tissue in various diameter (6-10 mm), usually growing on underneath of leaves, asexual generations of this wasp have not yet been recorded from Iran since it is very difficult to rear the gall and associated wasps in laboratory conditions. Often, wasps emerged from the galls are only the parasite wasps. This is the first report of Pediaspis aceris from Iran
