Abstract
Pteromalidae family with more than 3500 described species and 390 genera is one of the large parasitic wasps in the order Hymenoptera and superfamily Chalcidoidea (1). Also this family has 31 subfamilies. The members of this family are parasitoids of different insects' orders such as Coleoptera, Diptera, Hymenoptera and Homoptera. During study of Pteromalidae fauna of alfalfa fields of Maragheh region, East-Azarbaijan, in spring and summer of 2011, two female specimens of Arthrolytus (Hym.: Pteromalidae, Pteromalinae) were collected. The samples were collected using different methods such as Malaise trap, sweeping net and aspirator. The specimen that was identified by the second author as Arthrolytus glandium (Bouček) was collected from alfalfa fields of Agje-Kohol (37° 16' 06.97" - 46° 26' 48.63" and 1726m latitude) in 4th July 2011.
The specimens were deposited in Department of Plant Protection, Agricultural and Natural Resources Research of East-Azarbaijan, Tabriz, Iran.
This is the first record of the species from Iran. Previously, the species Arthrolytus ocellus (Walker) has been recorded from Iran (2). According to Graham (3), some morphological characters of A. glandium that facilitates its identification from other species are as follow: Antennae inserted low on the head. Second anellus in the antenna is twice as long as the first.
Malar space is about one third the length of an eye. Femurae are mainly dark in colour. Stigmal vein forms an acute angle with the postmarginal vein.
