 I just went to check the relevant scene in POA and as soon as Lupin 
bursts into the room and disarms Harry and Hermione,...
"Then Lupin spoke, in a very tense voice.
""Where is he, Sirius?""
"Harry looked quickly at Lupin.  He didn't understand what Lupin 
meant.  Who was Lupin talking about?"

Then Black points at Ron.  It's obvious that Lupin had seen 
Pettigrew's name on the map while he was in rat form.  However in 
checking further, I realized that the shreiking shack is not on the 
Marauders Map.  Lupin sees Peter with Ron, Harry and Hermione 
outside the Whomping Willow and sees Black (in dog form) rushing 
toward them.  When Snape looks at the map, he sees Lupin running 
along the passageway and out of sight.  No one ever "sees" anything 
in the shack while looking at the map, because it's not on Hogwarts 
grounds.  Canon does seem to indicate that everyone's "real" names 
appear on the map (ex. Barty Crouch in GoF).
As for Rita, no one saw her on the map in beetle form because on the 
3 occasions the book mentions her being on the grounds in that form, 
no one happens to be looking at the map.
