Another OT question: singular of "epagomenae"

Someday I'll get back to conlanging instead of just exploiting y'all for
your linguistic expertise for other purposes.  Honest!

Several calendars, starting with the ancient Egyptian, are solar with a
basic structure of 12 30-day months followed by 5 extra days called the
"epagomenae" (or "epagomenal days" in the boring English version).  Later
revisions introduced the concept of leap years, in which there was a 6th
epagomenal day.  My question is simple: what's the singular form of
"epagomenae"?   Is it "epgaomena"?  It looks Greek in origin rather than
Latin (although the -ae makes me suspicious; maybe it's a Latinization of a
Greek borrowing), and my Greek knowledge is pretty much limited to the
alphabet.
