The Senegalese National Teams are from the African country of Senegal.
Senegal lost in the final match of the 1998 Quidditch World Cup to a side from Malawi. The team had almost refused to play the match after their team mascots, the Yumboes, were arrested (Pm).
Senegal is in West Africa. Although they played in the 1998 Quidditch World Cup final, there is no mention of Quidditch in their Wikipedia entry (Wikipedia).
