Abstract
In this survey, the genus Orthocentrus Gravenhorst, 1829 (Hymenoptera: Ichneumonidae, Orthocentrinae) was studied in Tehran and Gilan provinces of Iran. A total of 154 specimens of the genus were collected using Malaise traps during 2010. The genus Orthocentrus and its seven species and one subspecies are new records for the fauna of Iran: O. asper (Gravenhorst, 1829),
O. castellanus Ceballos, 1963, O. hirsutor Aubert, 1969, O. protervus Holmgren, 1858, O. sannio Holmgren, 1858,
O. strigatus Holmgren, 1858, O. winnertzii Forster, 1850 and O. winnertzii planator Aubert, 1978. Seasonal abundance, emergence period, distribution and altitudinal changes in Orthocentrus fauna on two slopes of the Alborz Mountains are provided. Keys for identification of Orthocentrus species found in Gilan and Tehran provinces are presented based on males and females.
