Iran. ABSTRACT. Iranian species of the genus Erigorgus Forster, 1869 are taxonomically reviewed. The sampling was done using Malaise traps in Eastern provinces of Iran. Two species, Erigorgus cerinops (Gravenhorst, 1829) Received: 12 March, 2019 and Erigorgus fibulator (Gravenhorst, 1829) are reviewed, of which the second species represents occurrence of this genus in East of Iran. A brief diagnosis Accepted: based on the reliable morphological characters, as well as an illustrated key to 05 May, 2019 Iranian species are provided. The geographical distribution of the recorded Published: species in the Palaearctic regions is also discussed. 15 May, 2019 Subject Editor: Ali Asghar Talebi Key words: Erigorgus, Gravenhorstiini, Palaearctic, Parasitoid, South Khorasan Citation: Zardouei Heydari, M., Rakhshani, E. & Mokhtari, A.

Introduction Ichneumonidae, as one of the largest Anomaloninae of Iran have recently been families of Hymenoptera, include 44 investigated by various authors (Mojeni & recognized subfamilies, 1 601 genera and Sedivy, 2001; Masnadi-Yazdinejad & Jussila, 25 292 described species (Townes, 1969; Yu 2009; Zarepour et al., 2009; Klopfstein & et al., 2016). The subfamily Anomaloninae Baur, 2011; Nikdel & Diller, 2011; Hooshyar with 46 genera and 742 described species et al., 2012). Barahoei et al. (2012a) worldwide, and 210 species in the published a checklist of Ichneumonidae Palaearctic region (Yu et al., 2016) is known (Hymenoptera: Ichneumonoidea) of Iran, as one of the relatively diverse taxa within in which they listed four genera and 11 Ichneumonidae (Townes, 1971; Gauld, species of Anomaloninae, categorized 1976; Dasch, 1984). Adults of Anomaloninae within two tribes. Record of the fifth genus are usually can be easily recognized by the represented by Agrypon canaliculatum combination of distinctive morphological (Ratzeburg, 1844) (Nikdel & Diller, 2011) features as follows: loss of fore wing vein r-m, was not mentioned in the above mentioned a narrow pterostigma, propodeum coarsely checklist. The genus Erigorgus has recently reticulate sculptured, metasoma slender and been recorded from north of Iran laterally compressed (Gauld, 1978). (Hooshyar & Vafaei-Shoushtari, 2013).
