アメリカムシクイ科
The genus "Teretistris" was long thought to sit in the New World warbler family Parulidae, until a 2002 study examined 25 genera of New World warbler using mitochondrial and nuclear DNA found that six genera were best placed outside the family, including "Teretistris". Five of the genera had long been suspected to not sit comfortably inside Parulidae, but before this study there had never been a suggestion that "Teretistris" did not belong in the New World warbler family.
