What's the name of the Laureline eaters?

As I previously said, I saw Valerian and the City of a Thousand Planets some time ago, but the DVD hasn't been released yet, and, on the Internet, I can't find the name of the tribal extraterrestrial species (which is organized as an empire, and wich's Emperor is named "[beginning of the species' name] III") that "fishes" Laureline and offers her to the Emperor as a meal. I'm a Wikipedian, and the name of the species isn't on Wikipedia, so I want to write it, but I don't remember what it is! I thought it was "Doughan-Doughòns" or something like this (and my friend who saw the film with me thought it, too), as when Flitt knows his agent are in their territory he says the first word an then says something about the agents, and I remembered it was "Doughan". But, then, I discovered the "Doghan Daguis" name of the trio of informers and it made me think it was another name. So, do you know what it is? I'm reading a text at which contains the list of the Alpha species, but I don't know if I'll read the name. Goodbye, readers!
