Where an ellipsis exists, is there a term for the missing text? [duplicate]

Suppose there is a long sentence like:

This London hit show took America by storm, full of charm, humour and delightful songs that make it a perfect theatrical event for the entire family.

And you want to cut it off after an arbitrary specified amount of characters like so:

This London hit show took America by storm, full of charm, humour and delightful songs that make...

What is the name for the missing text indicated by the three-dot ellipsis?

Solution 1:

an omission or to omit a part of the sentence use an ellipsis

Ellipsis (plural ellipses; from the Ancient Greek: ἔλλειψις, élleipsis, "omission" or "falling short") is a series of dots that usually indicates an intentional omission of a word, sentence, or whole section from a text without altering its original meaning.

Solution 2:

The elided material. I would be tempted to say the elision, but I haven't found evidence that the noun is actually used in that way --maybe we could pioneer that usage.

Solution 3:

Since you're already familiar with orthographic term "ellipses" and (apparently) aren't looking for the editorial acts "elision", "excision", "truncation", "deletion" or @Malachi's perfectly suited "omission", maybe you're looking for a term which describes the elipsis' semantic role?

If so, I'd call ... the typographical analog to the "jump", "fold", or "spill line"; it teases or leads the reader into wanting to know more, so maybe you want to call it a "teaser".
