Relying on the OP claim that this roach came from Brazil is why I said Blaberus giganteus. Discoid are native to Cuba. Heck, there are a few new species of Blaberus finding their way into Brazil...it could be any one of them.looks like Blaberus discoidalis to me.
Only the species in which males have two yellow spots were supposedly moved to luci. Most Hormetica are still Hormetica no matter what taxonomic system you follow.The genus Hormetica doen´t exist, now it´s called Lucihormetica.
Your roach is a L. verrucosa or L. seabrai
