Have you considered that Snape is anti-Lupin because he was one of 
the gang that tormented him? That he sees Lupin being appointed DADA 
as rubbing salt in his wounds? That he may (would, most likely) have 
heard about the map from Filch, who confiscated it? Why else would he 
summon Lupin? He knows where and who it originated from.

vmonte responds:
Snape recognizes that the map belongs to Lupin's gang because he 
known their nicknames since they were all in high school. In the 
Snape pensieve chapter: James Potter and his gang are all calling 
themselves by their nicknames...
