Abstract
The subfamily Diplazontinae (Hym.: Ichneumonidae) has 340 described species to date (2, 5). A large scale sampling during 2010-2011 in the north of Iran resulted in reporting of 16 species of this subfamily from Iran (3) which of them two species belonged to the genus Homotropus Forster, 1869. Recently, two other species of the genus were reported from Kerman province (1, 4). Here, the fifth species of the genus, Homotropus longiventris, is reported for the first time from Iran. The second author confirmed the scientific name of this species. Specimen was deposited in the insect collection of College of Agriculture and Natural Resources of Darab, Shiraz University.
