Lusitania, historically refers to a territory which comprises all the Portuguese territory south of Douro river, and parts of Spain, of which a great part belonged once to Portugal as well. Nowadays, "Lusitanian" is essentially used to refer to any matter of Portuguese origin, instead of Iberian, as it seems to be the case in the target paper. The same applies to the term "Spanic" for matters of Spanish origin. Without undervaluing in any way or aspect the analyses of the authors and the merit and interest of this paper, the reference Lusitanian is clearly improper to refer to a question which revolves around the Perinea.
