What is "cnemophilidae"

The satinbirds or Cnemophilines, Cnemophilidae are a group of passerine birds which consists of three species found in the mountain forests of New Guinea. They were originally thought to be part of the birds-of-paradise family Paradisaeidae until genetic research suggested that the birds are not closely related to birds-of-paradise at all and are perhaps closer to Melanocharitidae. The current evidence suggests that their closest relatives may be the cuckoo-shrikes [Campephagidae].
