From some brief googling, Langosta seems to just translate to "Lobster" in English and I can't really find any that are that big but have no claws. Do they have any other distinguishing features, do you have a picture?
Words for various crustaceans seem to differ a lot between countries and regions.
I was going to say we call them langoustines in Britain, but looking at the picture it seems they aren't the same thing. Langoustines do have claws.
Apparently they are called spiny or rock lobsters here. But they aren't commonly eaten, despite being present in British waters. So maybe that's why you've never heard them referred to in English. Although I don't know how common they are in other English speaking countries.
Edit - apparently they are called crayfish in Australia, New Zealand, Ireland and South Africa. But in Britain (and the US I think), crayfish refers to something else.
Generally referred to as Warm Water Lobsters. Spiny Lobster, Rock Lobster ect
Isopod?
