A faunistic survey was conducted in Ardabil province (Northwestern
Iran), during spring 2013 to study the ichneumonids (Hymenoptera:
Ichneumonidae) associated with grasslands in this area. Samplings were carried
out by the sweeping net in natural grasslands, neighboring fields and orchards. A
total of twelve ichneumonid species belonging to nine genera and five subfamilies
were collected and identified. The species were identified as follow: Collyria
coxator (Villers, 1789), Diadromus collaris (Gravenhorst, 1829), Diplazon laetatorius
(Fabricius, 1781), Diplazon pectoratorius (Gravenhorst, 1829), Homotropus crassicornis
(Thomson, 1890), Homotropus elegans (Gravenhorst, 1829), Homotropus signatus
(Gravenhorst, 1829), Lysibia nana (Gravenhorst, 1829), Orthocentrus castellanus
(Ceballos, 1963), Picrostigeus setiger (Brischke, 1871), Promethes sulcator
(Gravenhorst, 1829) and Syrphophilus bizonarius (Gravenhorst, 1829). Homotropus
crassicornis is newly recorded for the fauna of Iran. An identification key to the
known species of the genus Homotropus Foerster, 1869 from Iran is presented.
