From dēfēnsō (“to defend”) + -trīx.
dēfēnsātrīx f (genitive dēfēnsātrīcis, masculine dēfēnsātor or dēfēnsor); third declension
In terms of form, this is the feminine counterpart of dēfēnsātor, while dēfēnstrīx is the feminine counterpart of dēfēnsor. However, it appears that dēfēnsātrīx has conventionally been used as the specifically feminine counterpart to dēfēnsor (when one is used) in the title Fidei Defensor/Defensatrix or Defensor/Defensatrix Fidei "Defender of the Faith".
