Books that are in the Septuagint but not in the Tanakh are called Anagignostkomena in the Eastern Orthodox Churches, Apocrypha (Biblical) by Protestants, and Deuterocanon by Catholics. What is the parallel term for books of the Old Testament that are included in Bibles (primarily Oriental Orthodox) that are in neither the Septuagint nor the Tanakh? The best I can invent is Pseudepigrapha (Biblical) which I don't really like.
