Finwitch here:

I agree - it won't appear. Because even if the Marauders HAD figured 
out there was one - (like Tom did, reading Hogwarts:a History, Myrtle, 
Hagrid, Aragog...) and then they WOULD have tried to find it -- they 
had to find, and possibly even enter - all those places appearing on 
the map... I think it was required to enter a place to put it onto the 
map. They may have figured out the basilisk etc. but NOT enter. (None 
of them is/was a parselmouth, after all)

Aside from the Chamber, there's also the Room of Requirement that 
doesn't appear on the map -- as the Marauders never found it. (Or 
Sirius would definately had told Harry about it instead of that 
corridor...). Of course, as Harry has found them, he might ADD those 
places onto the map. (Lupin can tell him how).
