The family Torymidae (Hymenoptera, Chalcidoidea) is distributed worldwide and contains two subfamilies with 67 genera and about 1100 extant species (Noyes, 2015). Torymidae have a large number of niches and feeding habits.
Most species of Megastigminae are phytophagous (seed-feeders) with a few entomophagous species, whereas species of Toryminae are primarily entomophagous. Some Toryminae are known as ectoparasitoid of gall-forming insects, parasitoids of mantid egg-cases, larvae of solitary bees and hyperparasitoid of butterflies' pupae (Askew, 1965, 1966, 2006b; Grissell, 1995, 2005; Janšta et al., 2013; Noyes, 2015).
The Iranian fauna of the Torymidae has been poorly studied. The first catalog of the Torymid wasp fauna of Iran was published by Peck (1963).
Later, a few more species records of this family from Iran were added (e.g. Ebrahimi and Ahmadian, 2002; Lotfalizadeh and Gharali, 2005; Fallahzadeh et al., 2008; Stojanova and Ghahari, 2009) and a few new species described (e.g.
Askew et al., 2006a; Zerova and Seryogina, 2008; Zerova et al., 2008). Fallahzadeh et al. (2009) provided a comprehensive check-list of the Iranian Torymidae consisting of 15 genera and 41 species of Torymidae.
More recently, Madjdzadeh et al. (2013) and Lotfalizadeh (2014) added some new records from Iran. Here, we provide further data on Torymidae in South-West Iran, add one genus and three species to the published records.
