Abstract
The subfamily Cremastinae (Hym.: Ichneumonidae) comprises 756 described species into 35 genera (5). These wasps distributed all over the world but their high species diversity mostly occurs in the tropic regions. Members of this subfamily are biologically koinobiont endoparasitoids of mainly Lepidoptera and in some cases of Coleoptera (4). Up to now, there have been reported 27 species of this subfamily from Iran (1; 3). Eight Malaise traps were installed in different regions of Amol County during 2016. Alcohol 75° was the killing and preservation medium of the collecting pots of these malaise traps. A total of 15 specimens of the subfamily Cremastinae were collected and then were identified as Dimophora evanialis using available descriptions and keys to the species of this genus (2). The genus and species of this parasitoid wasp are newly reported for the fauna of Iran (1). The specimens of this species are deposited in the insects collection of College of Agriculture and Natural Resources of Darab, Shiraz University.
The Genus Dimophora Förster, 1869: The adults of this genus can be distinguished from the other genera of this subfamily by the combination of the following characters: fore wing with a large diamond shaped areolet; hind femur with no tooth on ventral surface; ventral edges of the first tergite parallel and separated completely by the first sternite for their entire length; second tergite with no thyridiae and its epipleuron curved down (2). Two species of this genus are distributed in the Palaearctic realm (5).
