Internecivus raptus

I love the piece of art and I especially like that you used the creature's scientific nomenclature, but I also heard an other scientific name for the xenomorph: Linguafoeda acheronsis. Now according to scientific nomenclature rules, the first name coined is considered the official one, while the others are considered synonyms of the first one. Do you know if Internecivus raptus has been the first scientific name given to the Alien?
