There are a few notable Female Yautja (that are actually named characters) in the books and graphic novels:

 - Big Mama - From the comic AvP: Deadliest of the Species. A big
   Predator with no female features (breasts) and no special
   armor/costume. She is actually quite badass and survives the hunt.
 
 - Sister Midnight - from the Witchblade/Aliens/Darkness/Predator:
   Mindhunter crossover comic. Looks feminine, has breasts and has a
   dress like costume. Has a special relationship with Witchblade,
   fights some Aliens, detonates her self-destruct and dies.
   
 - Vagouti - From the Predator: If It Bleeds novel story Rematch (the
   story is a sequel to the book Predator: Turnabout). There is not much
   physical description on her but she is hunting together with her
   mate. They are both killed by humans.

There is also Machiko Noguchi, who is a human female who joined the Predators (she is often mistaken for a female Predator). There is more information and pictures about them here: [Female Yautja][1]
