Thirteen species of Pteromalidae are recorded from Southeast Iran in this study. Among the studied materials, one species is described as new (Sphegigaster persiana Mitroiu & Madjdzadeh, sp. nov.) and four species are recorded for the first time from Iran. Available biological data, geographical distribution as well as short taxonomic comments for each species are briefly mentioned.
