One of my friends has seen this insect-like species in water in the mountainous area in Iran (near Qom).
Looks like some species of tadpole shrimp. I couldn't tell you what species. There's really no other basis for identification other than these are extremely unique. As you can imagine, they're endemic to a variety of wetland environments. The take home point, however, is it's a crustacean rather than an insect.
