What is the largest terrestrial isopod species?

I believe that the largest length wise is Porcellio magnificus.

There seems to be some disagreement as to whether it's Porcellio magnificus or P. hoffmannseggi.

I think Porcellio expansus is bigger than both if you're looking at overall size but many Ligia are bigger than the very biggest Porcello.

I am trying some isopods that I think are smaller, don't recall the name at the moment.

Helleria brevicornis may be the bulkiest/heaviest terrestrial species, though rearing full grown adults takes a while compared to the others mentioned here.

Have you seen an adult Helleria? I've not even seen little ones.

I've seen pictures of adults, they're really large! And I have a breeding group myself, though they're far from full grown yet.

P mag for sure. P ornatus Nord is an equal in body mass to any P mag or hoff.
