It is the second time the 32-year-old has been suspended for the same offence having sat out nine weeks in 2013 for biting South Africa lock Eben Etzebeth in a Rugby Championship fixture.
Senatore was playing for the Buenos Aires-based Jaguares when he sunk his teeth into the arm of Sharks flank Keegan Daniel as the pair tussled in a ruck near the end of a tense 25-22 victory for the South African side in Velez Sarsfield.
Despite being a repeat offender, his most recent ban was reduced from the prescribed minimum of 12 weeks for what the SANZAAR judicial committee called his "good character, his playing record and his disciplinary record".
"The Judicial Committee deemed the act of foul play merited a low-end entry point of 12 weeks.
The Judicial Committee then added two weeks for aggravation as this was the player's second offence for biting," SANZAAR said in a statement on Monday.
