Yes it does exist is the simple answer. Here are a few thoughts about it and the future perfect.
The pluperfect is relatively uncommon in Greek even in the classical period. It is morphologically about as complex as verbs come. Most people are content to understand the Greek pluperfect as a grammatical equivalent of the English
past perfect (I had done), and in many ways that is not a bad understanding and quite adequate for most purposes.
Here are some examples of the pluperfect in the sense of an action completed before the past tense in a narrative. The first one is taken from
Burton (1900) page 44ff (page 63ff in the pdf);
John 9:22 wrote:ἤδη γὰρ συνετέθειντο οἱ Ἰουδαῖοι,
For the Jew(ish leader)s had already made a decision,
Matthew 7:25 wrote:τεθεμελίωτο γὰρ ἐπὶ τὴν πέτραν.
because it had had its foundations built on the rock
In addition to that equivalence to the English past perfect, the pluperfect also describes a state that used to exist - at a translation level English renders this type of past tense state as a simple past, but the Greek verb system uses a pluperfect with these verbs. Here are two of the examples that Burton gives;
Luke 4:41 wrote:ὅτι ᾔδεισαν τὸν χριστὸν αὐτὸν εἶναι.
because they [the demons] knew that he was the Christ.
John 18:16 wrote:ὁ δὲ Πέτρος εἱστήκει πρὸς τῇ θύρᾳ ἔξω.
Peter stood (a stative) outside beside the door.
As for the name, I originally learnt the name of this tense as
plusquamperfectum - the tense's Latin name - but as you know that the unguided paths of head-strong teenage self-taughts sometimes wander into unusual areas of the subject. Later when I went to on to study Greek with a teacher in a class with a textbook, it became obvious that the common name in English is pluperfect. When I went to University to study Classical Greek, the lecturers were aware of the Latin term, but didn't use it. The Greek name for the tense is ὑπερσυντέλικος.
I have never used the book, but on the assumption that Mounce's textbook is a popular / paperback work, it is unlikely that he would use the Latin or Greek terms. There is no other name that I am aware that it is known by in the English speaking world.
It could be that it has been deemed an intermediate level piece of grammar and has been skipped over. As a test of that, perhaps you could look for the
future perfect in the index. That is an even rarer perfect tense than the pluperfect. The only true example I know of that future perfect tense is Luke 19:40 in the Byzantine text-form (≈ Textus Receptus);
οἱ λίθοι κεκράξονται.
, in this place the modern scholarly texts have the simple future οἱ λίθοι κράξουσιν. The difference in meaning could be "If you were to keep yourselves silent, the rocks will have already cried out." vs. "If you keep yourselves silent, then the rocks will cry out." Usually, however, the future perfect is made up of two words (periphrasis), examples of which are found at Hebrews 2:13 and Matthew 18:18.
