You can look at the map of observations, they seem to have been observed across the country: https://www.inaturalist.org/observations?place_id=6818&preferred_place_id=6883&subview=map&taxon_id=136361
They do seem to be a bit more in the forests and around Tehran but that’s also where the most people are so hard to say if that’s a result of habitat or not. Oryctes elegans and agamemnon are apparently pests on date palms so theoretically they could occur wherever the palms are cultivated.
